What advertisers should actually take away
1 billion Bing MAUs is a real distribution shift
Bing crossed 1 billion monthly active users for the first time. That's been a long ramp — Edge default deployment, Copilot integration, and the chat-style search surface are all paying off. For Microsoft Advertising buyers, this means the addressable audience for Search and Audience Network campaigns is materially larger than it was a year ago. If you've kept Microsoft Ads at a small fraction of your Google budget out of habit, the math has shifted.
+12% ad revenue ex-TAC = volume + price per search
Microsoft attributed search ad growth to both "higher volume and revenue per search across Edge and Bing." That's the combination advertisers want to see — more searches AND higher monetization per search means Microsoft is genuinely deepening the marketplace, not just inflating CPCs. Compared to Google Search ads at +19%, Microsoft's +12% is a slower-growing market, but with less auction pressure for incumbents.
Copilot integration is reshaping search query mix
Bing's growth is increasingly Copilot-driven, which means a slice of "search" volume is now conversational. Conversational queries are longer, more contextual, and less aligned with traditional keyword bidding. If you haven't audited your Microsoft Advertising keyword strategy in 6+ months, you're likely under-bidding on the long-tail conversational queries Copilot generates. Pull your search-term reports for Q1 2026 and look for the long-tail surge.
More Personal Computing -1% — context, not concern
The MPC segment that houses Bing ads was down 1% YoY at $13.19B, but that decline is mostly Xbox/Surface drag. Search ads inside that bundle grew 12%. If you only read the segment headline you'd miss the actual ad story. For agencies presenting Q1 to clients, lead with the search ad number, not the segment number.
$37B annualized AI revenue funds the ad-targeting roadmap
Microsoft's AI revenue run rate hit $37B+. A meaningful chunk of that infrastructure investment routes back into ad-platform features — Performance Max-like automation, audience modeling, and bidding ML on the Microsoft Advertising side. Expect more aggressive defaults and AI-suggested settings showing up in the UI through 2026. Document any auto-applied recommendations before they take effect.
What to check in your account this week
- 1 Re-evaluate Microsoft Ads share of search budget. If you're at <10% of your Google search budget despite a Bing audience now at 1B MAUs, the math probably says expand.
- 2 Pull Q1 2026 search-term reports. Look for long-tail conversational queries from Copilot. Bid on the ones with intent.
- 3 Audit auto-applied recommendations. Microsoft Ads, like Google, increasingly defaults toward AI suggestions. Turn off auto-apply for changes you'd want to review.
- 4 Verify Edge/Bing placement. Bing growth is partly distribution-driven. Make sure your campaigns aren't excluding Edge or Bing-default surfaces unintentionally.
