A
A/B test
An A/B test (also called a split test) is an experiment where you compare two versions of a page, ad, or email. Half of your visitors see version A, the other half sees version B. By measuring which variant performs better — for example, generating more clicks or conversions — you make data-driven decisions instead of guessing. Essential for conversion rate optimization.
Above the fold
Above the fold is the portion of a webpage that is immediately visible without scrolling. The term originates from the newspaper industry: the section above the fold. In online marketing, this is the most valuable screen real estate. Your key message, call-to-action, and value proposition should be placed here. On mobile, this area is smaller, so prioritize carefully what you display.
Ad extensions
Ad extensions (now called ad assets) are additions to your Google Ads that display extra information. Think of sitelinks, call extensions, location information, or prices. They make your ad larger and more informative, boosting your CTR without additional cost per click. Google automatically selects which extensions to show based on relevance.
Ad group
An ad group is a collection of ads and keywords within a Google Ads campaign organized around the same theme. Good structure means: a small cluster of closely related keywords per ad group with matching ad copy. This improves your quality score and lowers your cost per click.
Ad rank
Ad rank determines the position of your ad in Google's search results. It is calculated based on your bid, quality score, expected impact of extensions, and the context of the search query. A higher ad rank means a better position. You can appear above a competitor who bids more if your quality score is better.
Ad (advertisement)
An ad is a paid piece of content that promotes your product, service, or brand to a target audience. In online marketing, the most common formats are: search ads (text-based in Google), display ads (visual banners), social ads (on platforms like Meta and LinkedIn), and video ads (YouTube). Each format has its own best practices for setup and optimization.
Affiliate marketing
Affiliate marketing is a model where external partners (affiliates) promote your products and receive a commission for each sale or lead they generate. The affiliate places a tracking link on their website or social media. Well-known affiliate networks include CJ Affiliate, ShareASale, and Rakuten. It is a performance-based model: you only pay for results.
AI marketing
AI marketing is the use of artificial intelligence for marketing tasks. Think of AI-generated content, automated bidding strategies, predictive analytics, chatbots, and personalized recommendations. Research shows that companies using AI achieve an average 30-40% efficiency gain. AI does not replace the strategist but dramatically accelerates execution.
Algorithm
An algorithm is a set of rules and calculations that a computer uses to make decisions. In marketing, the most important algorithms are those of Google (determines search results), Meta (determines what you see in your feed), and YouTube (determines recommendations). Marketers try to understand these algorithms and leverage them to gain more visibility.
Alt text
Alt text (alternative text) is a description you add to images on your website. Search engines cannot "see" images, so they use alt text to understand what is depicted. It is also important for accessibility: screen readers read alt text aloud to visually impaired visitors. Describe concisely what you see, including relevant keywords.
Analytics
Analytics is the collection, measurement, and analysis of website data to gain insights into visitor behavior. Google Analytics 4 (GA4) is the most widely used tool. You measure visitor counts, traffic sources, conversions, bounce rate, and user paths, among other things. Without analytics, you are flying blind — every serious marketing strategy begins with proper measurement.
Anchor text
Anchor text is the clickable text of a hyperlink. For example: in the sentence "learn more about SEO," the word 'SEO' is the anchor text. Search engines use anchor text as a signal to understand what the linked page is about. Use descriptive anchor text instead of 'click here' — that helps both users and your SEO.
API
An API (Application Programming Interface) is a connection that allows two software systems to communicate with each other. In marketing, you use APIs to connect tools: for example, linking your CRM to your email marketing tool, or automatically pulling Google Ads data. APIs make marketing automation possible and eliminate manual copy-paste work between platforms.
Attribution
Attribution is assigning a conversion to the correct marketing channel or touchpoint. A customer may first see a Facebook ad, then search for your brand on Google, and buy through an email link. Which channel gets the credit? Attribution models (first-click, last-click, data-driven) determine this. Proper attribution is crucial for allocating your marketing budget wisely.
Authority (Domain Authority)
Domain Authority (DA) is a score from 1 to 100 that indicates how well a website performs in search engines. The score was created by Moz and is determined by factors such as the number and quality of backlinks. A higher DA means a better chance of strong rankings. News websites often score 80+, while an average SMB website scores between 15-40.
GDPR (General Data Protection Regulation)
The GDPR (General Data Protection Regulation) is the European privacy law that governs how companies may collect and process personal data. For marketers, this means: cookie banners, consent for email marketing, privacy-friendly tracking, and a clear privacy policy. Violations can result in fines of up to 4% of your annual revenue.
B
B2B marketing
B2B marketing (business-to-business) targets companies as customers, not consumers. The buying cycle is longer, multiple decision-makers are involved, and order values are typically higher. Effective B2B channels include LinkedIn, SEO, content marketing, and email campaigns. The focus is on lead generation, thought leadership, and building trust.
B2C marketing
B2C marketing (business-to-consumer) targets individual consumers. The buying cycle is shorter and emotion plays a bigger role than in B2B. Popular channels include Instagram, Google Shopping, TikTok, and e-commerce platforms. The focus is on brand recognition, direct conversions, and tapping into consumer needs and impulses.
Backlink
A backlink is a link from an external website to your website. Backlinks are one of the most important ranking factors for SEO. The more high-quality, relevant websites that link to you, the more Google considers your site authoritative. Not all backlinks are equal: a link from a major news outlet is worth far more than a link from an unknown blog.
Banner
A banner is a visual ad displayed on websites, usually as an image or animation. Banners are part of display advertising and are purchased through networks like the Google Display Network. Common formats include leaderboard (728x90), medium rectangle (300x250), and skyscraper (160x600). The average CTR for banners is low (0.05-0.1%), but they are effective for brand awareness.
Bid strategy
A bid strategy determines how you bid in Google Ads. Manual bidding gives you full control, while smart bidding (such as Target CPA or Maximize Conversions) uses AI to automatically determine the optimal bid per auction. The right choice depends on your campaign goal, budget, and the amount of conversion data available.
Black hat SEO
Black hat SEO includes techniques that violate search engine guidelines to rank higher quickly. Examples: buying backlinks, keyword stuffing, cloaking, and doorway pages. Google penalizes these practices, causing you to disappear entirely from search results. Always use white hat SEO for sustainable results.
Blog
A blog is a section on your website where you regularly publish articles on topics relevant to your target audience. Blogging is a pillar of content marketing and SEO: each article is a new page that can rank in Google. Good blog content attracts organic traffic, builds authority, and aids lead generation by guiding visitors into your funnel.
Bounce rate
The bounce rate indicates what percentage of visitors leave your website without performing a second action. In GA4, this has been replaced by 'engagement rate,' which is the opposite. A high bounce rate may indicate irrelevant content, slow load times, or poor user experience. Average benchmarks vary by industry: 40-60% is normal for blogs, 20-40% for e-commerce.
Brand awareness
Brand awareness is the degree to which your target audience knows and recognizes your brand. It is the first step in the marketing funnel: people need to know you exist before they buy from you. You build brand awareness with display advertising, social media, video marketing, and PR. It is difficult to measure directly, but surveys and branded search volume provide indicators.
Branded keyword
A branded keyword is a search query that contains your brand name, such as 'Searchlab contact' or 'Nike running shoes'. These keywords have a high conversion rate because the searcher already knows you. It is smart to also advertise on your own brand name in Google Ads — otherwise competitors can appear at the top when someone specifically searches for you.
Breadcrumb
A breadcrumb is a navigation element that shows the hierarchical position of a page. For example: Home > Blog > SEO Tips. Breadcrumbs improve user experience (visitors know where they are), help search engines understand site structure, and can appear as a rich result in Google. Always implement them with structured data for maximum SEO benefit.
Budget
Your marketing budget is the amount you allocate for all your marketing activities. In Google Ads, you set a daily budget per campaign; in social ads, a campaign or lifetime budget. A rule of thumb: SMBs spend 5-15% of their revenue on marketing. Allocate your budget based on ROI data — invest more in channels that demonstrably convert.
Buyer persona
A buyer persona is a semi-fictional profile of your ideal customer, based on market research and real customer data. It describes demographics, behavior, goals, pain points, and information needs. For example: 'Marketing Mary, 35, marketing manager at an SMB, looking for ways to generate more leads on a limited budget.' Personas help you create more targeted content and campaigns.
BANT
BANT stands for Budget, Authority, Need, and Timeline — four criteria to determine whether a lead qualifies as a sales opportunity. Does the prospect have budget? Are they the decision-maker? Do they have a genuine need? And is there a concrete timeline? BANT is primarily used in B2B sales to prioritize leads and focus your sales time on the most promising prospects.
C
Cache
A cache is a temporary storage location for web page data. Browser caching stores files locally so repeat visits load faster. Google also has its own cache of web pages (the 'cached version'). For marketers, caching is important because it improves your page speed — a ranking factor — and because changes may only become visible to visitors after the cache refreshes.
Call-to-action (CTA)
A call-to-action is a clear prompt for your visitor to take a specific action. 'Request a quote,' 'Download the whitepaper,' or 'Contact us' are classic examples. A good CTA is action-oriented, creates urgency, and stands out visually. Place CTAs strategically: above the fold, after persuasive content, and in your emails. The CTA is the linchpin of your landing page.
Campaign
A campaign is an organized marketing effort with a specific goal, budget, and time period. In Google Ads, a campaign is the highest organizational level, with ad groups and ads beneath it. A campaign can target brand awareness, lead generation, or direct sales. Each campaign has its own settings for targeting, budget, and bid strategy.
Canonical URL
A canonical URL tells search engines which version of a page is the 'original' when the same content is accessible via multiple URLs. This prevents duplicate content issues. You implement it with a <link rel="canonical"> tag in the HTML. Essential for online stores where products are accessible via multiple category paths, or for pages with URL parameters.
Cart abandonment
Cart abandonment is when a visitor adds products to their shopping cart but does not complete the purchase. On average, 70% of shoppers abandon their cart. With retargeting ads and automated abandoned cart emails, you can recover a portion of these. Common causes: unexpected shipping costs, mandatory account creation, or a checkout process that is too long.
Chatbot
A chatbot is an automated conversation system on your website that answers visitor questions. Simple chatbots work with preset answers, while AI chatbots (such as those based on GPT or Claude) conduct natural conversations. Chatbots improve customer service response time, qualify leads, and are available 24/7. Popular tools: Intercom, Drift, and HubSpot Chat.
Click-through rate (CTR)
The click-through rate is the percentage of people who click on your link or ad after seeing it. Formula: (clicks / impressions) x 100. A Google Ads search ad averages 3-5% CTR, while an organic search result at position 1 averages around 30%. A low CTR indicates insufficiently relevant or attractive titles and descriptions. CTR is a key quality indicator.
CMS
A CMS (Content Management System) is software that lets you manage your website without coding. WordPress (43% of all websites), Shopify, Wix, and Squarespace are well-known examples. A good CMS makes it easy to create pages, update content, and manage SEO settings. Your choice of CMS affects your capabilities for technical SEO and site performance.
Content cluster
A content cluster is an SEO strategy where you link a pillar page (main page) to multiple related cluster articles via internal links. For example: a pillar page about 'online marketing' links to articles about SEO, SEA, content marketing, and social media. This shows Google that you are an expert on the topic and strengthens the rankings of all pages in the cluster.
Content marketing
Content marketing is the strategic creation and distribution of valuable, relevant content to attract and engage your target audience. The goal is not to sell directly but to build trust. Formats include blog articles, videos, podcasts, whitepapers, and infographics. Content marketing works long-term: it generates organic traffic, builds authority, and nurtures leads through the funnel.
Conversion
A conversion is the moment when a visitor completes a desired action: a purchase, form submission, download, or phone call. It is the ultimate goal of every marketing campaign. Track your conversions accurately through Google Ads conversion tracking and GA4 events. Without conversion tracking, it is impossible to determine which channels and campaigns are actually delivering results.
Conversion rate
The conversion rate is the percentage of visitors who convert. Formula: (conversions / visitors) x 100. An average website converts at 2-3%, while top performers achieve 5-10%. Improve your conversion rate with landing page optimization, better UX design, faster load times, and more persuasive copy. Every percentage point improvement directly generates more revenue.
Cookie
A cookie is a small text file that a website places on your computer to remember information. There are functional cookies (remember your language preference), analytical cookies (measure visitor behavior), and tracking cookies (follow your browsing behavior for advertising). Due to GDPR and the disappearance of third-party cookies, marketing is increasingly shifting toward first-party data and cookieless tracking.
Core Web Vitals
Core Web Vitals are three performance metrics that Google uses as a ranking factor: LCP (Largest Contentful Paint — loading speed), INP (Interaction to Next Paint — interactivity), and CLS (Cumulative Layout Shift — visual stability). Check your scores in Google Search Console or PageSpeed Insights. Websites with good Core Web Vitals receive a small ranking advantage in search results.
Cost per acquisition (CPA)
The CPA (cost per acquisition) is the average amount you pay to achieve one conversion. Formula: total ad spend / number of conversions. If you spend $1,000 and generate 20 leads, your CPA is $50. CPA is the most important metric for evaluating campaign profitability. Always compare your CPA with the value of a conversion.
Cost per click (CPC)
The CPC is the amount you pay per click on your ad. In Google Ads, the CPC is determined through an auction: you set a maximum CPC, but often pay less (the actual CPC). Average CPCs vary widely, from $0.50 for simple keywords to $15+ for competitive terms in insurance or legal services.
Cost per mille (CPM)
CPM (cost per thousand impressions) is a pricing model where you pay per 1,000 times your ad is displayed. It is widely used for display and video ads aimed at brand awareness. Typical CPMs on the Google Display Network range from $1-5, on YouTube $5-15, and on LinkedIn $25-60. With CPM, the focus is on reach, not clicks.
Crawl budget
The crawl budget is the number of pages a search engine crawler (like Googlebot) is willing to visit on your site within a given period. Large websites with thousands of pages need to account for this: if Googlebot uses up your crawl budget on unimportant pages, your important pages may not get indexed. Optimize with robots.txt, internal links, and a sitemap.
CRM
A CRM (Customer Relationship Management) is software that helps you manage customer relationships. You store contact details, interactions, deals, and communication history. Popular CRMs include HubSpot, Salesforce, and Pipedrive. A good CRM gives your sales and marketing team a complete view of each customer, makes lead nurturing scalable, and prevents leads from falling through the cracks.
CRO
CRO (Conversion Rate Optimization) is the systematic improvement of your website to convert more visitors. You achieve this with A/B testing, user research, heatmaps, form optimization, and UX improvements. CRO is extremely profitable: you get more results from your existing traffic without additional ad spend. An optimized landing page can double your conversion rate.
Cross-selling
Cross-selling is offering complementary products to a customer who is already buying something. For example: a phone case with a phone, or Google Ads management alongside an SEO package. It is more effective than acquiring new customers because you are selling to someone who already trusts you. Amazon reportedly generates 35% of their revenue through cross-selling with 'customers also bought' recommendations.
Customer journey
The customer journey describes all the steps a person goes through from first encountering your brand to purchase and beyond. The standard phases are: awareness, consideration, decision, and loyalty. By mapping out the customer journey, you identify where your marketing efforts have the most impact.
Customer lifetime value (CLV/LTV)
The customer lifetime value is the total revenue a customer generates throughout their entire relationship with your company. Formula: average order value x purchase frequency x customer lifespan. If a customer spends an average of $100/month and remains a customer for 3 years, the CLV is $3,600. CLV helps you determine how much you can invest in customer acquisition — your CPA should always be lower than your CLV.
D
Dashboard
A dashboard is a visual overview of your most important marketing data and KPIs in one place. Tools like Google Looker Studio, HubSpot, and Databox let you build dashboards with charts, tables, and scorecards. A good dashboard shows at a glance whether you are on track: traffic, conversions, costs, ROI. Build dashboards around decisions, not around data.
Data-driven marketing
Data-driven marketing is basing marketing decisions on data rather than gut feeling. You analyze customer behavior, campaign performance, and market trends to inform your strategy. This requires good tracking, analytics tools, and the ability to interpret data. Companies that work data-driven perform demonstrably better: higher ROI, lower costs, and better customer experience.
Demand generation
Demand generation is creating demand for your product or service among your target audience. It goes beyond lead generation: you build awareness and desire in people who may not yet know they need your solution. Methods include thought leadership content, webinars, podcasts, and social media. Demand gen focuses on the long term and feeds your lead generation pipeline.
Demographics
Demographics encompass the statistical characteristics of your target audience such as age, gender, income, education, and location. Ad platforms like Google Ads and Meta Ads allow you to target based on demographic characteristics. Demographic data helps you tailor your message, but always combine it with behavioral data and intent signals for the most effective targeting.
Direct traffic
Direct traffic consists of visitors who reach your website by typing your URL directly into the browser or using a bookmark. In GA4, traffic also appears as 'direct' when the source is untraceable, for example clicks from email clients or apps. High direct traffic can indicate strong brand awareness, but it is partly a catch-all for unknown sources.
Display advertising
Display advertising is showing visual ads (banners, images, videos) on third-party websites. Through the Google Display Network, you reach more than 90% of all internet users. Display ads are primarily used for brand awareness and remarketing, not for direct conversion. Responsive display ads automatically adapt to the available ad format.
DNS
DNS (Domain Name System) is the system that translates domain names (like searchlab.nl) into IP addresses that computers understand. For marketers, DNS is relevant when setting up a website, configuring email authentication (SPF, DKIM, DMARC), and implementing tracking subdomains. DNS issues can make your website unreachable and disrupt email delivery.
Domain authority
Target audience
Your target audience is the specific group of people you want to reach with your marketing. A target audience is defined based on demographics, interests, behavior, and needs. The more specific your target audience, the more relevant your message and the more efficient your budget. 'Everyone' is not a target audience — segment and prioritize. Make your target audience concrete with buyer personas.
Drip campaign
A drip campaign is a series of automated emails sent at preset intervals after a specific trigger. For example: someone downloads a whitepaper and then receives 6 emails over 4 weeks that progressively dive deeper into the topic. Drip campaigns are ideal for lead nurturing and onboarding. They run on autopilot through your marketing automation platform.
Dynamic content
Dynamic content is website content that automatically changes based on who the visitor is. For example: a returning customer sees different offers than a new visitor, or content adapts to the visitor's location or device. This increases relevance and conversion. Tools like HubSpot and Optimizely enable dynamic content personalization without technical knowledge.
DSP
A DSP (Demand-Side Platform) is software that enables advertisers to automatically purchase ad inventory across multiple ad exchanges. It is the technology behind programmatic advertising. A DSP bids on ad space in real time, often in milliseconds while a web page loads. Well-known DSPs include DV360 (Google), The Trade Desk, and Amazon DSP. DSPs are primarily relevant for larger advertisers with significant media budgets.
E
E-commerce
E-commerce is selling products or services online. This includes online stores, marketplaces (Amazon, eBay), and social commerce. Essential components are product pages, checkout optimization, payment methods, and shipping. The U.S. e-commerce market exceeds $1 trillion annually. Success factors: fast load times, mobile experience, trust signals, and smart remarketing.
E-E-A-T
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — four quality criteria used by Google's manual reviewers. Since 2022, 'Experience' has been added. Google values content written by people with demonstrable expertise and firsthand experience. Demonstrate E-E-A-T through author pages, references, certifications, and real-world practical examples on your website.
Email automation
Email automation is the automatic sending of emails based on triggers, behavior, or time schedules. Examples: a welcome email after signup, a reminder for an abandoned cart, a birthday discount. Automated emails outperform bulk email: 70% higher open rates and 150% higher click rates. Tools like Mailchimp, ActiveCampaign, and HubSpot make this accessible for any business.
Email marketing
Email marketing is using email as a marketing channel for communication, promotion, and customer retention. Formats include newsletters, drip campaigns, transactional emails, and promotional mailings. Email marketing delivers an average ROI of $36 per dollar invested — the most profitable digital channel. Success depends on your list building, segmentation, content, and timing.
Engagement rate
The engagement rate measures how much interaction your content generates, expressed as a percentage. On social media: (likes + comments + shares + saves) / reach x 100. In GA4, the engagement rate replaces bounce rate: the percentage of sessions that lasted longer than 10 seconds, contained a conversion, or viewed 2+ pages. A high engagement rate indicates relevant, compelling content.
Evergreen content
Evergreen content is content that remains relevant over time, regardless of when someone reads it. 'What is SEO?' is evergreen; 'SEO trends 2025' is not. Evergreen content is the backbone of a good content strategy: it attracts organic traffic month after month without constant updates. Invest in comprehensive, high-quality evergreen articles and periodically keep them up to date with minor revisions.
Exit rate
The exit rate is the percentage of visitors who leave your site from a specific page. Unlike bounce rate (only valid for the entry page), exit rate is calculated for every page in a session. A high exit rate on your checkout page is alarming; on your 'thank you' page, it is perfectly logical. Analyze exit rates to discover where visitors drop off in your funnel.
F
Facebook Ads
Facebook Ads (now part of Meta Ads) is Meta's advertising platform for advertising on Facebook, Instagram, Messenger, and the Audience Network. With billions of users worldwide, it offers enormous reach. The power lies in the targeting capabilities: demographics, interests, behavior, and lookalike audiences. Facebook Ads are effective for both e-commerce and B2B lead generation.
Featured snippet
A featured snippet is a highlighted answer that Google displays at the top of search results (position zero). It contains a summary of the answer, sourced from a web page. Formats include paragraph, list, and table snippets. A featured snippet provides enormous visibility but can also cost clicks if the answer is already fully displayed in Google (zero-click search).
Feed
A feed is a structured data file containing product information that you share with advertising platforms. Google Shopping, Facebook Catalog, and comparison sites use feeds to display your products. A product feed contains title, description, price, stock status, images, and more. Feed optimization — enriching titles, improving images, adding attributes — directly impacts your ad performance.
Frequency
Frequency is the average number of times an individual sees your ad. A frequency of 3 means each person in your target audience has seen your ad an average of three times. Too low: your message does not land. Too high: ad fatigue and irritation. The sweet spot is usually between 3-7 for awareness campaigns. Monitor frequency to prevent ad fatigue.
Funnel
A funnel visualizes the path potential customers travel from first contact to conversion. The classic breakdown is TOFU (Top of Funnel — awareness), MOFU (Middle of Funnel — consideration), and BOFU (Bottom of Funnel — decision). Each stage requires different content and channels. The funnel narrows toward the bottom: of 1,000 website visitors, perhaps 20 become customers.
First-party data
First-party data is data you collect directly from your customers and visitors: website behavior, purchase history, email addresses, CRM data. Unlike third-party data (purchased from external parties), first-party data is reliable, privacy-compliant, and exclusively yours. With the disappearance of third-party cookies, first-party data is becoming increasingly valuable for targeting and personalization.
G
GA4 (Google Analytics 4)
GA4 is the current version of Google Analytics, the most widely used web analytics platform in the world. It works event-based instead of session-based like its predecessor Universal Analytics. GA4 measures behavior across websites and apps, works better with privacy restrictions, and offers predictive capabilities through machine learning. Every marketer should be able to read and interpret GA4.
GDN (Google Display Network)
The Google Display Network is a network of more than 2 million websites, apps, and videos where you can show display ads through Google Ads. You reach 90%+ of all internet users this way. GDN is ideal for remarketing and brand awareness but less suited for direct conversion. Targeting options include contextual (based on page content), demographic, and interest-based targeting.
Geo-targeting
Geo-targeting is directing your ads or content at users in a specific geographic location. In Google Ads, you can target by country, region, city, or even a radius around an address. Local businesses use geo-targeting to reach only people in their service area. It prevents waste: why advertise in San Francisco when you only serve New York?
Google Ads
Google Ads is Google's advertising platform for paid advertising in search results, on YouTube, in Gmail, and on the Display Network. It works on an auction model: you bid on keywords and pay per click (CPC) or per 1,000 impressions (CPM). Google Ads is the largest online advertising platform in the world and often the first channel businesses start with.
Google Business Profile
A Google Business Profile (formerly Google My Business) is your free business listing in Google Maps and local search results. You manage your business name, address, hours, photos, and reviews here. It is crucial for local SEO: businesses with a complete and optimized profile appear more often in the local 'map pack.' Actively request reviews — they are an important ranking factor.
Google Search Console
Google Search Console (GSC) is a free tool from Google that shows how your website performs in search results. You see which search queries you rank for, your average position, CTR, and any technical issues. GSC is indispensable for SEO: it reveals indexing problems, mobile usability errors, and Core Web Vitals. Every website should be connected to GSC.
Google Tag Manager (GTM)
Google Tag Manager is a free tag management system that lets you place tracking codes (tags) on your website without editing the source code. Once installed, you can manage Google Analytics, conversion tracking, remarketing pixels, and other scripts from GTM. This saves developer time and reduces errors. GTM works with triggers (when a tag fires) and variables (what data is sent).
Growth hacking
Growth hacking is a marketing approach focused on rapid, experimental growth with a limited budget. Growth hackers combine marketing, data, and technology to find scalable growth methods. Think of viral referral programs (Dropbox), product-led growth (Slack), and creative acquisition tactics. It differs from traditional marketing by emphasizing speed, experiments, and scalability over long-term strategy.
GTM
See Google Tag Manager. In a B2B context, GTM can also stand for Go-To-Market: the strategy for bringing a new product or service to market. A GTM strategy includes your target audience, value proposition, pricing model, distribution channels, and launch plan. A solid GTM strategy significantly increases your chances of a successful market introduction.
H
H1/H2/H3 (headings)
Headings are HTML elements that define the structure of your page. H1 is the main title (use only one per page), H2s are section headings, and H3s are subheadings. A good heading structure helps both readers and search engines understand your content. Include relevant keywords in your headings, but always write them primarily for the reader, not for Google.
Heatmap
A heatmap is a visual representation of where visitors click, scroll, and move their mouse on your website. Warm colors (red/orange) show areas with high activity, cool colors (blue/green) show low activity. Heatmaps reveal whether visitors see your CTAs, how far they scroll, and which non-clickable elements they click on. Tools like Hotjar and Microsoft Clarity offer free heatmap functionality.
Hero section
The hero section is the large, prominent area at the top of a web page — the first thing visitors see. It typically contains a headline, subheadline, visual element (image or video), and call-to-action. Your hero must communicate in 3-5 seconds: what do you do, for whom, and why should I keep reading. It is the most important part of your landing page.
Hreflang
Hreflang is an HTML attribute that tells search engines which language and country a page is intended for. It prevents Google from showing the wrong language version to users. Essential for multilingual websites: if you have an English and a Dutch version, hreflang ensures that English speakers see the English version and Dutch speakers see the Dutch version in search results.
HTML
HTML (HyperText Markup Language) is the foundational language for building web pages. It defines the structure of a page with elements like headings, paragraphs, links, and images. As a marketer, you do not need to be an HTML expert, but basic knowledge helps with SEO (meta tags, heading structure, alt text) and debugging tracking codes or landing pages.
HTTP/HTTPS
HTTPS (HyperText Transfer Protocol Secure) is the encrypted version of HTTP, the protocol browsers and servers use to communicate. The 'S' stands for Secure: data is sent encrypted. Google confirmed HTTPS as a ranking factor in 2014. Websites without HTTPS receive a 'Not Secure' warning in the browser. An SSL certificate is now free through Let's Encrypt.
HubSpot
HubSpot is an all-in-one marketing, sales, and CRM platform popular with SMBs. It offers email marketing, landing pages, forms, chatbots, lead scoring, CRM, reporting, and more. The free version is surprisingly complete. HubSpot's philosophy revolves around inbound marketing: attracting customers with valuable content instead of interrupting them with ads.
I
Impression
An impression counts every time your ad or search result is shown to someone. An ad that receives 10,000 impressions has been displayed 10,000 times — but that says nothing about how many people actually saw or noticed it. Impressions are the basis for calculations like CTR (clicks / impressions) and CPM (cost per 1,000 impressions).
Inbound marketing
Inbound marketing is a strategy where you attract customers by offering valuable content, rather than actively reaching out to them (outbound). You publish blog articles, whitepapers, and videos that your target audience finds through Google and social media. Visitors become leads, leads become customers. The concept was popularized by HubSpot and forms the basis of many B2B marketing strategies.
Indexing
Indexing is the process by which a search engine adds your page to its database (index). If your page is not indexed, it cannot appear in search results. Google indexes pages by crawling them with Googlebot. You can monitor indexing in Google Search Console. Troubleshooting? Check your robots.txt, noindex tags, and sitemap. Technical SEO largely revolves around indexing.
Influencer marketing
Influencer marketing is partnering with influential individuals on social media to promote your brand or product to their followers. This ranges from mega-influencers (100K+ followers) to micro-influencers (1K-10K) who have a niche audience. Micro-influencers often have higher engagement rates and are more affordable. Key: choose influencers who fit your brand, not just based on follower count.
Instagram is a visual social media platform owned by Meta with over 2 billion monthly active users worldwide. Content formats include feed posts, Stories, Reels, and Live. Instagram is strong for B2C brands in lifestyle, food, fashion, and beauty. Advertising runs through Meta Ads Manager. Trends: Reels (short video) dominates reach, while Stories are ideal for engagement and direct interaction.
Search intent
Search intent is the goal behind a search query. Google distinguishes four types: informational ('what is SEO'), navigational ('Searchlab contact'), commercial ('best SEO agency'), and transactional ('hire SEO agency'). Content that does not match the intent will not rank, no matter how good it is. Always analyze the current top-10 to understand the intent behind a keyword.
Internal linking
Internal linking refers to links from one page on your website to another page on the same website. Internal links help visitors navigate, distribute 'link equity' (SEO value) across your pages, and help Google understand the structure and hierarchy of your site. A solid internal linking structure — with descriptive anchor text — is one of the most underrated SEO tactics.
IP address
An IP address is a unique numerical address that identifies every device on the internet. In marketing, IP information is used for geo-targeting, fraud detection, and (in B2B) identifying companies that visit your website. Under the GDPR, you cannot simply store IP addresses without consent. GA4 anonymizes IP addresses by default to remain privacy-compliant.
K
Keyword
A keyword is a word or phrase you want to be found for in search engines. Keywords are the foundation of both SEO and SEA. There are short-tail keywords ('shoes'), long-tail keywords ('red running shoes size 10'), and branded keywords ('Nike Air Max'). Choose keywords based on search volume, competition, and relevance to your business.
Keyword difficulty
Keyword difficulty (KD) is a score indicating how hard it is to rank in Google's top 10 for a specific keyword. Tools like Ahrefs and SEMrush calculate KD on a scale of 0-100, based on the authority of the current top-10 results. A KD of 0-30 is relatively easy, 30-60 moderate, and 60+ difficult. New websites should start with low KD keywords.
Keyword research
Keyword research is systematically investigating which search terms your target audience uses. You map out search volume, competition, intent, and relevance. Tools: Google Keyword Planner (free), Ahrefs, SEMrush. Good keyword research is the foundation of every SEO strategy. Focus not only on volume but especially on intent: 100 searchers with buying intent are better than 10,000 informational searchers.
KPI
A KPI (Key Performance Indicator) is a measurable value that indicates how successful you are in achieving a goal. Marketing KPIs include: leads per month, conversion rate, CPA, ROAS, organic traffic, and email open rate. Choose a maximum of 3-5 KPIs per channel. Too many KPIs lead to confusion — focus on the metrics directly tied to your business goals.
Quality Score
The Quality Score is a rating of 1-10 that Google Ads assigns to your keywords, based on three factors: expected CTR, ad relevance, and landing page experience. A higher score means lower CPCs and better ad positions. A score of 7+ is good. Improve your score by writing highly relevant ad copy and directing visitors to an optimized landing page.
L
Landing page
A landing page is a page specifically designed to convert visitors into leads or customers. Unlike a regular web page, a landing page focuses on a single action, has no navigation menu, and minimal distractions. Every ad campaign deserves its own landing page that matches the ad copy and search intent of the visitor.
Lead
A lead is a potential customer who has shown interest in your product or service, for example by filling out a form, downloading a whitepaper, or reaching out. Leads are the fuel for your sales team. They are categorized as MQL (marketing qualified lead) or SQL (sales qualified lead) based on their qualification level and purchase readiness.
Lead generation
Lead generation is the systematic process of attracting and capturing potential customers. Methods include content marketing, paid ads, social media, events, cold outreach, and partnerships. The goal is to identify anonymous website visitors and collect their contact information so you can follow up. A strong lead generation strategy is the engine behind B2B growth.
Lead magnet
A lead magnet is a valuable piece of content you offer for free in exchange for contact information. Examples: e-book, whitepaper, checklist, template, webinar, or free audit. A good lead magnet solves a concrete problem for your target audience and is immediately usable. The quality of your lead magnet determines how many people are willing to share their email address.
Lead nurturing
Lead nurturing is building a relationship with leads who are not yet ready to buy. Through automated email sequences, personalized content, and targeted retargeting, you guide them through the funnel. The goal: stay top-of-mind until the lead is ready to buy. Research shows that nurtured leads make 47% larger purchases than non-nurtured leads. Patience and relevance are key.
Lead scoring
Lead scoring is assigning points to leads based on their actions and characteristics. For example: website visit (+5), whitepaper download (+10), correct job title (+15), director (+20). Leads with high scores are passed to sales. This ensures your sales team only spends time on the most promising leads. CRMs like HubSpot and Salesforce offer built-in lead scoring.
Link building
Link building is acquiring backlinks from external websites to your site. It is one of the three most important SEO pillars (alongside content and technical SEO). Effective link building methods include guest blogging, digital PR, broken link building, and creating link-worthy content (research, tools, infographics). Quality over quantity: one link from an authoritative site is worth dozens of weak links.
LinkedIn Ads
LinkedIn Ads is LinkedIn's advertising platform, ideal for B2B marketing. Its unique strength: you can target by job title, company size, industry, seniority, and skills — data other platforms do not have. LinkedIn Ads are more expensive than other platforms (CPC $5-15+), but lead quality is higher. Formats include Sponsored Content, Message Ads, and Lead Gen Forms.
Local SEO
Local SEO focuses on improving your visibility for local search queries. Think 'restaurant near me' or 'plumber in Brooklyn.' Core components include your Google Business Profile, local backlinks, NAP consistency (Name, Address, Phone), local content, and reviews. 46% of all Google searches have local intent — for local businesses, this is gold.
Long-tail keyword
A long-tail keyword is a longer, more specific search query with lower search volume but higher conversion potential. 'Shoes' is short-tail, 'red leather women's shoes size 8 buy' is long-tail. Long-tail keywords are less competitive, cheaper in Google Ads, and attract visitors who know exactly what they are looking for. Together, they often account for the majority of your organic traffic.
Lookalike audience
A lookalike audience is a target group that closely resembles your existing customers in terms of characteristics. Meta Ads and LinkedIn Ads create these by analyzing your customer list and finding similar profiles. Upload your customer database, and the platform finds people with the same demographics, interests, and behavior. It is one of the most effective targeting methods for reaching new, relevant prospects.
M
Marketing automation
Marketing automation is automating repetitive marketing tasks with software. Think of email flows, lead scoring, social media scheduling, and personalized content. Tools like HubSpot, ActiveCampaign, and Mailchimp make this possible. It saves time, increases consistency, and scales your marketing. AI further enhances marketing automation with smarter segmentation and predictive models.
Marketing funnel
See Funnel.
Marketing qualified lead (MQL)
An MQL is a lead that the marketing team has assessed as promising based on engagement and profile characteristics. An MQL has, for example, viewed multiple pages, downloaded a whitepaper, and fits the ideal customer profile in terms of company size. The MQL is passed to sales for further qualification to SQL. The MQL-to-SQL conversion rate is an important marketing KPI.
Match type
A match type in Google Ads determines how broadly or narrowly your ad is triggered by search queries. There are three types: broad match (also synonyms and related terms), phrase match (the meaning must match), and exact match (only the specific query and close variants). The right match type strategy limits irrelevant clicks.
Meta Ads
Meta Ads is the overarching advertising platform for Facebook, Instagram, Messenger, and the Audience Network. Campaigns are managed through Meta Ads Manager. You can target by demographics, interests, behavior, custom audiences (your own data), and lookalike audiences. With Advantage+, Meta offers increasingly AI-driven campaign optimization. Meta Ads is the second-largest advertising platform in the world after Google.
Meta description
A meta description is the short description (maximum 155 characters) that appears below your page title in search results. It is not a direct ranking factor, but it does influence your CTR — and thereby indirectly your rankings. Write compelling meta descriptions that answer the search intent, contain a call-to-action, and spark curiosity to click through.
Meta tags
Meta tags are HTML elements in the head of your page that provide information to search engines and social media platforms. The most important are the title tag, meta description, robots meta tag (index/noindex), canonical tag, and Open Graph tags (for social media previews). Correct meta tags are a baseline requirement for good SEO and ensure your pages display correctly in search results and social shares.
Micro-conversion
A micro-conversion is a smaller action that indicates a visitor is on the way to your ultimate conversion goal. Examples: viewing a page for more than 30 seconds, starting a video, adding a product to the cart, or sharing a blog post. Micro-conversions help you understand and optimize the funnel, especially when you have few macro-conversions (purchases, leads) to optimize for.
Mobile-first
Mobile-first means your website is primarily designed for mobile devices and only then for desktop. Google uses 'mobile-first indexing': the mobile version of your site determines your rankings. Over 60% of web traffic occurs on mobile. A mobile-first approach requires: fast load times, readable text without zooming, tappable buttons, and a streamlined mobile experience.
N
Native advertising
Native advertising is paid content that seamlessly blends with the form and feel of the platform where it appears. It looks like editorial content but is sponsored. Examples: sponsored articles on news sites, promoted posts on social media, and 'recommended content' blocks. Native ads outperform traditional banners in engagement because they feel less intrusive.
Negative keyword
A negative keyword is a term you exclude in your Google Ads campaign so your ad does not appear for that search query. Example: if you sell luxury watches, you exclude 'cheap' and 'free'. Negative keywords prevent irrelevant clicks and save budget. Regularly review your search terms report and add new exclusions — it is an ongoing optimization process.
Nofollow
Nofollow is an HTML attribute (rel="nofollow") that tells search engines not to count a link as a ranking signal. It is used for paid links, user-generated content (comments, forums), and links you do not want to endorse. Google has also introduced rel="sponsored" (paid links) and rel="ugc" (user-generated content) as more specific variants.
Noindex
A noindex tag tells search engines not to include a page in their index. Use this for pages you do not want to show in search results: thank-you pages, internal search results pages, test pages, or pages with thin content. Implementation: via a meta tag (<meta name="robots" content="noindex">) or via an X-Robots-Tag HTTP header.
O
Off-page SEO
Off-page SEO encompasses all optimizations outside your own website that influence your rankings. The most important component is link building: acquiring high-quality backlinks. Additionally, brand mentions, social signals, reviews, and your Google Business Profile count. Off-page SEO builds authority and trust — it tells Google that other websites value you.
Omnichannel
Omnichannel marketing is a strategy where you provide a seamless, consistent experience across all channels — online and offline. The customer experiences no difference between website, social media, email, physical store, and customer service. It differs from multichannel (multiple channels operating independently) in that all channels are integrated and customer data is shared. Requires a good CRM as the foundation.
On-page SEO
On-page SEO encompasses all optimizations on your own website that improve your rankings. Core components: title tags, meta descriptions, heading structure, content quality, internal links, URL structure, image optimization, and page speed. On-page SEO is the foundation of your SEO strategy — it is entirely within your control and often delivers the fastest results.
Open rate
The open rate is the percentage of recipients who open your email. Formula: (opened emails / delivered emails) x 100. Average open rates vary by industry from 15-30%. Since Apple's Mail Privacy Protection (2021), the open rate has become less reliable because Apple automatically loads pixels. Therefore, also focus on click rate as a more reliable metric for email engagement.
Organic traffic
Organic traffic consists of visitors who reach your website through unpaid search results in Google, Bing, or other search engines. It is the result of your SEO efforts. Organic traffic is valuable because it is 'free' (after the initial SEO investment) and sustainable: a well-ranking page can deliver traffic for years. 53% of all website traffic is organic.
Outbound marketing
Outbound marketing is actively reaching out to potential customers through push methods. Think cold calling, cold emailing, direct mail, TV commercials, and display ads. It is the opposite of inbound marketing (attracting customers to you). Outbound can be effective in B2B prospecting when you reach the right person with a relevant message at the right time.
P
Page speed
Page speed is how fast your web page loads. It is both a ranking factor for SEO and a crucial factor for user experience. 53% of mobile visitors leave a site that takes longer than 3 seconds to load. Measure your speed with Google PageSpeed Insights or GTmetrix. Improve it with image compression, lazy loading, browser caching, and minimizing JavaScript.
Paid search
Paid search is advertising in search engine results. In practice, this almost always means Google Ads, which holds 90%+ of the search market in the U.S. Paid search results appear at the top and bottom of the search results page with a 'Sponsored' label. The advantage: you appear immediately on relevant search queries without waiting months for SEO results.
Pay per click (PPC)
PPC is an advertising model where you pay per click on your ad. Google Ads and Microsoft Ads are the best-known PPC platforms. The advantage: you only pay when someone actually shows interest by clicking. The CPC varies by industry, keyword, and competition. A good PPC strategy combines keyword research, compelling ad copy, and optimized landing pages.
Performance Max
Performance Max is a Google Ads campaign type that uses AI to automatically show ads across all Google networks: Search, Display, YouTube, Gmail, Maps, and Discover. You supply assets (text, images, videos) and Google's machine learning determines the optimal combination and placement. Performance Max often delivers good results but provides less control and insight than traditional campaign types.
Persona
See Buyer persona.
Pillar page
A pillar page is a comprehensive, overarching page about a broad topic that links to detailed cluster articles on subtopics. This glossary is an example. Pillar pages are a proven SEO strategy: they demonstrate topical authority, strengthen internal links, and often rank for competitive head terms. Combine a pillar page with 10-20 cluster articles for maximum effect.
Pixel
A pixel (or tracking pixel) is a small piece of code you place on your website to track visitor behavior. The Meta Pixel (formerly Facebook Pixel) tracks actions on your site and links them to Facebook users for conversion tracking and remarketing. Google has similar tracking through the Google Tag. Pixels are essential for conversion optimization but require GDPR-compliant consent management.
Podcast marketing
Podcast marketing involves using podcasts as a marketing channel: starting your own podcast, advertising in existing podcasts, or appearing as a guest. Podcasts build thought leadership and a personal connection with your audience. Over 40% of the U.S. population listens to podcasts. It is a growing channel, especially effective for B2B brands that want to demonstrate in-depth expertise.
Position zero
Position zero is the position above the first organic search result in Google, reserved for featured snippets. You 'win' position zero by writing content that answers a question concisely and clearly, preferably in a paragraph, list, or table. It provides enormous visibility but can also cost clicks if the answer is fully contained in the snippet (zero-click search).
PPC
See Pay per click.
Programmatic advertising
Programmatic advertising is the automated buying of ad inventory through software and algorithms, in real time. Instead of manually negotiating with publishers, a DSP purchases ad space in milliseconds across millions of websites. It enables advanced targeting, personalization, and scale. Programmatic now accounts for 80%+ of all display ad spending in the U.S.
Q
Quality Score
See Quality Score (under K).
Query
A query (search query) is the text a user types into a search engine. The difference from a keyword: a keyword is the term you target, a query is what the user actually searches. Google Ads' search terms report shows which queries triggered your ads. Analyze these queries regularly to discover new keyword opportunities and exclude irrelevant searches.
R
RankBrain
RankBrain is Google's AI system that helps rank search results. It was introduced in 2015 as one of the first machine learning components in Google's algorithm. RankBrain interprets search intent — especially for new or ambiguous queries — and learns from user behavior which results are most relevant. It makes Google better at understanding the intent behind search queries.
Ranking
A ranking is the position of your web page in Google's organic search results for a specific keyword. Position 1 receives an average of 30% of all clicks, position 10 only 2-3%. Rankings are influenced by hundreds of factors, with content quality, backlinks, and technical SEO being the most important. Monitor your rankings with tools like Google Search Console, Ahrefs, or SEMrush.
Reach
Reach is the unique number of people who have seen your content or ad. It differs from impressions: if one person sees your ad three times, that is 3 impressions but 1 reach. Reach is a core metric for awareness campaigns. On social media, you measure organic reach (unpaid) and paid reach. Organic reach has been declining for years — paid reach is often necessary.
Remarketing
Remarketing (also called retargeting) is re-engaging people who have previously visited your website or interacted with your brand. Through cookies or pixels, you track visitors and show them targeted ads on other websites, social media, or in search results. Remarketing is extremely effective: these visitors already know you. On average, 3-5x higher conversion rate than cold traffic.
Responsive design
Responsive design is a web design approach where your website automatically adjusts to the screen size of the device — desktop, tablet, or smartphone. This is achieved with flexible grids, scalable images, and CSS media queries. Responsive design is essential: Google uses mobile-first indexing and 60%+ of web traffic is mobile. A non-responsive site loses visitors and rankings.
Retargeting
See Remarketing.
Return on ad spend (ROAS)
ROAS measures how much revenue you generate per dollar of ad spend. Formula: ad revenue / ad costs. A ROAS of 5 means $5 revenue per $1 spent. ROAS is the go-to metric for e-commerce advertisers. Note: ROAS measures revenue, not profit. Factor in your margins to determine whether a campaign is actually profitable. Minimum ROAS depends on your margins.
Return on investment (ROI)
ROI measures the return on your investment. Formula: (revenue - investment) / investment x 100%. An ROI of 200% means you make two dollars of profit for every dollar invested. ROI is the ultimate metric to determine whether your marketing is profitable. The difference from ROAS: ROI accounts for all costs (including labor, tools, overhead), while ROAS only considers ad spend.
Rich snippet
A rich snippet is an enhanced search result in Google that displays additional information beyond the standard title and description. Examples: star ratings, prices, FAQ accordions, recipe information, or event data. Rich snippets are generated based on structured data (schema markup) on your page. They significantly increase your CTR because your result stands out more and provides more information.
Robots.txt
Robots.txt is a file in the root of your website that tells search engine crawlers which pages or sections they may or may not crawl. It is not a security measure (the content is still accessible) but directs crawl budget. Commonly used to exclude admin pages, duplicates, and unimportant pages from crawling. An error in your robots.txt can de-index your entire site.
S
Sales qualified lead (SQL)
An SQL is a lead that the sales team has approved as a genuine sales opportunity. An SQL has the right profile characteristics, has shown sufficient interest, and is ready for a sales conversation. The step from MQL to SQL is critical: marketing qualifies on engagement, sales on purchase readiness and budget. A smooth handoff between marketing and sales is essential for conversion to customer.
Schema markup
Schema markup is code you add to your website to give search engines extra context about your content. It is based on the schema.org vocabulary. Types include: Organization, Product, Article, FAQ, Review, Event, LocalBusiness. Schema markup leads to rich snippets in Google, which boost your CTR. Implement it via JSON-LD in the head of your page — the format recommended by Google.
Search engine
A search engine is a system that searches the internet, indexes content, and presents results based on search queries. Google dominates with 90%+ market share in the U.S., followed by Bing (3-7%). Search engines crawl pages, determine relevance via algorithms, and rank results. The two ways to be visible: organically via SEO or paid via SEA.
SEA
SEA (Search Engine Advertising) is paid advertising in search engines. In practice, this almost always means Google Ads. You bid on keywords and your ad appears at the top of search results. Advantages: immediate traffic, measurable results, full budget control. Disadvantages: it stops as soon as you stop paying. SEA and SEO complement each other perfectly in a complete search strategy.
SEM
SEM (Search Engine Marketing) is the umbrella term for all marketing activities in search engines — both paid (SEA) and organic (SEO). In practice, however, SEM is often used as a synonym for SEA. A complete SEM strategy combines both: SEO for sustainable organic traffic and SEA for immediate visibility on competitive or commercial keywords.
SEO
SEO (Search Engine Optimization) is optimizing your website to rank higher in organic (unpaid) search results. The three pillars are: technical SEO (crawlability, speed, structured data), on-page SEO (content, keywords, meta tags), and off-page SEO (backlinks, authority). SEO is a long-term investment that delivers sustainable, high-quality traffic.
SERP
The SERP (Search Engine Results Page) is the page of results Google displays after a search query. A modern SERP contains not just ten blue links, but also ads, featured snippets, People Also Ask boxes, local packs, knowledge panels, and images. SERP analysis — understanding what Google shows for your target keywords — is essential for your SEO and content strategy.
Session
A session is a series of interactions a user performs on your website within a certain time window. In GA4, a session ends after 30 minutes of inactivity or at midnight. A user can have multiple sessions per day. Sessions are a basic measurement in analytics: you track sessions, users (unique visitors), and pageviews to get a picture of your website traffic.
Shopping campaign
A Shopping campaign in Google Ads shows product ads with an image, title, price, and store name in search results and on the Shopping tab. The ads are generated based on your product feed in Google Merchant Center. Shopping campaigns are essential for e-commerce: they deliver high CTRs and purchase-intent traffic. Optimize your feed titles and images for the best results.
Sitemap
A sitemap is an XML file that lists all pages on your website, so search engines can crawl and index them more efficiently. You submit your sitemap via Google Search Console. A sitemap is especially important for large websites, new websites, and sites with deep pages that are hard to find through internal links. Most CMS platforms automatically generate a sitemap.
Smart bidding
Smart bidding is a collection of automated bidding strategies in Google Ads that use machine learning to optimize your bids in real time. Types: Target CPA (target cost per conversion), Target ROAS (target return), Maximize Conversions, and Maximize Conversion Value. Smart bidding analyzes dozens of signals per auction (device, location, time of day, search history) to determine the optimal bid.
Social media marketing
Social media marketing is using platforms like LinkedIn, Instagram, Facebook, TikTok, and YouTube to promote your brand, build an audience, and generate leads or sales. It encompasses both organic content (posts, reels, stories) and paid advertising. Success on social media requires consistency, platform-specific content, and a balance between providing value and promoting.
Social proof
Social proof is the psychological principle that people follow the behavior of others. In marketing, this translates to reviews, testimonials, client logos, case studies, numbers ('10,000+ customers'), and social media followers. Social proof builds trust and lowers purchase barriers. Place it strategically on your landing page: near the CTA, in the hero, and next to pricing information.
Split test
See A/B test.
Structured data
Structured data is code that enriches your website with context for search engines. It tells Google not only what is on your page, but what it means. Implement it with JSON-LD and the schema.org vocabulary. Structured data can lead to rich snippets, knowledge panels, and other enhanced search results that increase your visibility and CTR.
T
Target audience
See Target audience (under D).
Targeting
Targeting is directing your ads at a specific group of people based on characteristics such as demographics, location, interests, behavior, or search intent. Each ad platform offers its own targeting options. Google Ads primarily targets by keywords (intent), Meta Ads by demographics and interests, and LinkedIn Ads by professional characteristics. Sharper targeting means more relevant ads and lower costs.
Technical SEO
Technical SEO encompasses the technical optimizations that ensure search engines can correctly crawl, index, and render your website. Components: site speed, mobile optimization, SSL certificate, XML sitemap, robots.txt, canonical tags, structured data, Core Web Vitals, and crawl budget management. Technical SEO is the foundation: without good technical setup, even the best content cannot rank.
Title tag
The title tag is the HTML element that defines your page's title — it appears as the clickable blue link in Google's search results and in the browser tab. It is the most important on-page SEO factor. Keep it under 60 characters, place your primary keyword at the front, and make it compelling enough to click. Every page should have a unique, relevant title tag.
Top of funnel (TOFU)
TOFU is the top stage of the marketing funnel: awareness. In this stage, your potential customer discovers their problem or need and encounters your brand for the first time. TOFU content is educational and broad: blog articles, infographics, social media posts, and videos. The goal is not to sell directly but to attract attention and guide the visitor into the funnel toward MOFU and BOFU.
Tracking
Tracking is measuring and recording user actions on your website and in your campaigns. Without tracking, you cannot determine what works and what does not. Tracking includes: Google Analytics (website behavior), conversion tracking (measuring goals), UTM parameters (identifying campaign sources), and pixel tracking (cross-platform behavior tracking). Proper tracking setup is prerequisite number one for data-driven marketing.
Traffic
Traffic is the number of visitors to your website. It is categorized by source: organic (via search engines), paid (via ads), direct (URL typed), referral (via links on other sites), social (via social media), and email. More traffic is not automatically better — it is about quality: visitors who match your target audience and convert. Focus on relevant traffic, not volume.
Trigger
A trigger is a specific action or event that initiates an automated marketing action. Examples: a form submission triggers a welcome email, an abandoned cart triggers a reminder email, a price change triggers a notification. Triggers are the foundation of marketing automation — they ensure the right message is sent at the right time without manual intervention.
U
Unique visitors
Unique visitors is the number of individual people who visit your website in a given period. A person who visits your site three times counts as one unique visitor with three sessions. In GA4, this metric is called 'Users' (active users). It is a more important metric than pageviews or sessions because it shows how many different people you actually reach.
URL
A URL (Uniform Resource Locator) is the web address of a page, for example https://searchlab.nl/en/glossary. For SEO, a good URL structure is important: keep URLs short, descriptive, and readable, use hyphens as separators, and include your primary keyword. Avoid long URLs with parameters, session IDs, or illegible characters. A clean URL structure helps both users and search engines.
User experience (UX)
UX (user experience) encompasses all aspects of a user's interaction with your website or product. Good UX means: easy navigation, fast load times, clear structure, readable text, and a logical path to conversion. Google measures UX signals via Core Web Vitals and uses them as a ranking factor. Investing in UX simultaneously improves your SEO, conversion rate, and customer satisfaction.
User-generated content (UGC)
UGC is content created by your customers or users: reviews, photos, videos, social media posts, and forum contributions. UGC is powerful because it is authentic — consumers trust content from other users more than brand messages. Encourage UGC with hashtag campaigns, review requests, and contests. It delivers free content, social proof, and improves your SEO through fresh, unique content.
UTM parameters
UTM parameters are tags you add to URLs to track the source, medium, and campaign of your traffic in Google Analytics. The five parameters are: utm_source (source, e.g. 'google'), utm_medium (medium, e.g. 'cpc'), utm_campaign (campaign name), utm_term (keyword), and utm_content (variant). UTM tracking is essential for determining which campaigns and channels deliver the most results.
V
Video marketing
Video marketing is using video as a marketing tool. Formats: product demos, tutorials, testimonials, webinars, social media reels, and YouTube content. Video is the most consumed content format: 80%+ of internet traffic is video. It increases engagement, improves conversion (landing pages with video convert 80% better), and contributes to SEO through YouTube — the second-largest search engine.
Viewport
The viewport is the visible portion of a web page on the user's screen. On mobile, the viewport is smaller than on desktop. The viewport meta tag (<meta name="viewport">) tells the browser how to scale the page. Without this tag, mobile displays the desktop version shrunk down. A correctly configured viewport is a prerequisite for responsive design and mobile-first SEO.
Viral marketing
Viral marketing is creating content that spreads rapidly because people share it en masse. Viral content triggers emotion (humor, surprise, recognition), is easy to share, and has an element of novelty. Virality is not fully predictable, but you can increase the chances with proven formats: challenges, memes, controversial takes, and user-generated campaigns.
Voice search
Voice search is searching via spoken commands, for example through Siri, Google Assistant, or Alexa. Voice searches are typically longer and more conversational than typed queries. Optimize for voice search by answering questions in your content, targeting featured snippets, and strengthening local SEO — many voice searches have local intent ('restaurant near me').
W
Webinar
A webinar is an online seminar or presentation you deliver live to an audience. It is a powerful B2B lead generation tool: participants register with their contact information and demonstrate direct interest in your expertise. Webinars build authority, generate warm leads, and can be repurposed as on-demand content. Popular platforms: Zoom, GoTo Webinar, and Microsoft Teams.
Website optimization
Website optimization is the continuous improvement of your website in terms of speed, user experience, conversion, and discoverability. It encompasses technical SEO, CRO, UX design, content optimization, and performance improvement. A well-optimized website loads fast, converts visitors, and ranks high in Google. It is not a one-time project but an ongoing process of measuring, testing, and improving.
White hat SEO
White hat SEO includes techniques that fully comply with search engine guidelines. It revolves around creating valuable content, providing a good user experience, and earning backlinks through legitimate means. White hat SEO delivers sustainable results without the risk of penalties. It is the opposite of black hat SEO. At Searchlab, we work exclusively with white hat methods.
Wireframe
A wireframe is a schematic, visual blueprint of a web page that shows the structure and functionality without visual design. It is a skeleton: where do the navigation, headings, text, images, and CTAs go? Wireframes are created during the planning phase of a website or landing page. Tools: Figma, Balsamiq, or even pen and paper. A wireframe prevents costly changes later in the development process.
X
XML sitemap
See Sitemap. An XML sitemap is specifically the machine-readable format (in XML code) that lists all URLs on your website with metadata such as last-modified date and priority. You submit it to Google Search Console and Bing Webmaster Tools. An XML sitemap accelerates the indexing of new and updated pages, especially for larger websites with hundreds or thousands of pages.
Y
YouTube Ads
YouTube Ads are video advertisements you place on YouTube through Google Ads. Formats: skippable in-stream (skip after 5 seconds), non-skippable (15 seconds), bumper ads (6 seconds), discovery ads, and Shorts ads. YouTube has over 2 billion monthly active users worldwide and is the second-largest search engine. YouTube Ads are effective for brand awareness, product demonstrations, and remarketing with video content.
YouTube SEO
YouTube SEO is optimizing your videos to rank higher in YouTube's search results and recommendations. Key factors: video title (with keyword), description, tags, thumbnail, watch time, engagement (likes, comments), and CTR. YouTube's algorithm rewards videos that keep viewers watching longer. Also optimize your channel page with keywords and publish consistently. YouTube videos also rank in Google's search results.
Z
Zero-click search
A zero-click search is a search query where the user finds the answer directly in Google without clicking through to a website. This happens via featured snippets, knowledge panels, calculators, and direct answers. An estimated 60%+ of all Google searches are zero-click. For marketers, this means: optimize for brand visibility in the SERP, not just for clicks.
Search intent
See Search intent (under I).
Search volume
Search volume is the estimated number of times a keyword is searched per month. Tools like Google Keyword Planner, Ahrefs, and SEMrush display search volumes. High search volume means more potential traffic but also more competition. Search volume alone is insufficient: always consider keyword difficulty, search intent, and relevance to your business. A relevant keyword with a volume of 100 is better than an irrelevant one with 10,000.
Keyword research
See Keyword research (under K).
