Google’s Gemini-powered AI Overviews—those AI-generated summaries at the top of search results—are no longer just a quick-hit resource. They’re officially part of Google’s ad ecosystem.
Here’s how we got here
🔍 May 2024: Testing
Google began experimenting with ads in AI Overviews, gauging how users would respond to sponsored content woven into AI summaries. This was a trial-and-error phase to calibrate the model between relevance and disruption.
📣 October 3, 2024: Go time!
Google kicked off the wide rollout of ads in AI Overviews, declaring that both ads within the summaries and those alongside them would appear for users across the United States. Key details of the rollout include:
- Mobile First: Ads debuted exclusively on mobile devices. Hard to say exactly why, but I'm betting it has something to do with mobile users tending to only consume the AI result, and not keep scrolling to the traditional SERPs.
- Commercial Context: Ads only trigger when a search query has a “commercial angle.” (As illustrated by The Verge.)
- Transparency: Sponsored content is clearly labeled to differentiate it from organic AI-generated answers.
