Microsoft Ads, formerly Bing Ads, runs search ads on Bing and the Microsoft Search Network. Google remains by far the largest search engine: in October 2026 it had 91.05% of search engine referrals worldwide, against 4.8% for Bing (Statcounter). On desktop the picture is different: there Bing reached 15.03% worldwide and 18.8% in the US.
That desktop audience, LinkedIn profile targeting and ads inside Copilot are the main reasons advertisers add Microsoft Ads next to Google Ads. Microsoft says Bing passed 1 billion monthly active users for the first time in the quarter to March 2026, and that its search advertising revenue (excluding traffic acquisition costs) grew 12% in the quarter to September 2026.
