Google AI Overviews: the opt-out button, and why to think twice

Google switched on AI Overviews and AI Mode in France on 22 July 2026, the last major European market to get them. Belgium has had them for months already. The real news is elsewhere: a new button in Search Console that lets site owners opt out of these generative surfaces. Here is what to check before touching it.

1. What just changed, and why it matters for Belgium

Google's official announcement, signed by the head of Google France, confirms the rollout of AI Overviews and AI Mode across mobile, desktop and the Google app. AI Overviews show a summary at the top of the results page, with links to the web. AI Mode is a separate conversational experience, powered by Gemini, usable with text, voice and images: Google states that an AI Mode search takes on average three times longer than a traditional one. AI Overviews claim 2.5 billion monthly users worldwide, AI Mode more than one billion. For a Belgian SME that also sells or communicates in French toward France, or simply watches that market as a bellwether, this accelerated timeline deserves real attention, not a quick skim.

2. The Search Console button: a visibility switch, not a simple setting

Since June 2026, Google has offered a Search Console control that lets a site owner decide whether to appear in AI Overviews and AI Mode. The key point: sites that opt out then receive no more traffic or impressions from those features. They remain normally indexed and ranked in classic search results, and Google states this choice is not used as a ranking signal. In practice, for most sites, switching on this opt-out means giving up a visibility channel without getting anything back, not the lost clicks, and not the data that would let you measure the real impact of these surfaces on your traffic.

3. Why clicks are dropping, and which pages are exposed

A Pew Research Center study, cited by several specialist outlets, found that a search showing an AI summary leads to a click on a classic result in only 8% of cases, versus 15% without a summary. And 26% of searches with an AI Overview end immediately after it appears, versus 16% without one. The most exposed queries are informational (definitions, how-to guides), comparative ("X versus Y") and multi-part. Transactional queries remain, for now, largely spared. An SME whose traffic mostly comes from product pages will feel the shock more slowly than a site that lives off its advice blog.

The AI angle, humans first

A monitoring tool can continuously watch the Search Console AI performance report, flag any change to the opt-out status, and isolate the pages most dependent on informational traffic. That is a real time saver. But deciding whether to opt in or out of these surfaces, and how to restructure content to earn a citation rather than just a click, remains an expert call: AI executes. Expertise decides, and watches.
