Google has added an opt-out toggle in Search Console letting website owners block their content from appearing in AI Overviews and AI Mode. The feature was mandated by the UK’s Competition and Markets Authority — the world’s first binding conduct requirement on Google for AI-generated search — and is live for testing now, with full enforcement beginning June 17, 2026.
Google began rolling out the toggle inside Google Search Console on June 3, following a CMA order under the UK’s Digital Markets, Competition and Consumers Act 2024. 9to5Google first reported the details of the opt-out mechanism. Publishers testing the feature have a two-week window before it goes enforceable — and the decision they make could reshape how their content appears across the web.
The Regulatory First That Forced Google’s Hand
The CMA called its June 3 order a “world first” — the first time any regulator has imposed a binding requirement that a search engine give publishers a legal right to opt out of AI-generated summaries. The order was made under the UK’s Digital Markets, Competition and Consumers Act 2024, a law that gives regulators new power over designated “strategic market status” platforms. Google is the first company designated under the law.
The CMA’s concern: AI Overviews aggregate publisher content and answer user queries without sending traffic back to the source sites. Publishers argued this was unfair use of their work. The opt-out toggle is Google’s compliance move — but critics argue the choice it creates is illusory.
How the Toggle Works — and What It Doesn’t Cover
Website owners can activate the toggle in Search Console to prevent their pages from being used in AI Overviews, AI Mode results, and AI Overviews in Discover. Crucially, opting out does not affect standard organic search rankings — Google has confirmed this repeatedly. Publishers can block AI aggregation without losing their spot in ten blue links.
The major limitation: the opt-out explicitly excludes the Gemini app. Publishers who opt out of Search AI features still have no control over whether their content appears in Gemini. Gemini operates under different terms, and the CMA order did not extend to it. Google plans to roll the toggle out globally after the UK testing phase.
The Trade-Off That Has No Good Answer
For publishers, the choice is genuinely hard. AI Overviews have become a significant discovery surface — a full opt-out removes your content from an increasingly important part of how people encounter information in Search. But staying opted in means your content trains and feeds a system that, in many cases, answers the user’s question without a click.
The Great American AI Act moving through Congress has no equivalent publisher protection clause. For now, the UK opt-out is the only formal mechanism any publisher has — and its limits are significant. The enforcement date of June 17 means publishers have days, not weeks, to decide.
Frequently Asked Questions
What is the Google AI Overviews opt-out?
It is a toggle in Google Search Console that lets website owners block their content from appearing in Google’s AI Overviews and AI Mode results. The feature was mandated by the UK’s CMA under the Digital Markets, Competition and Consumers Act 2024, and is currently being tested with UK publishers before a global rollout.
Does opting out of AI Overviews hurt your Google search ranking?
No. Google has confirmed that activating the opt-out toggle does not affect a site’s ranking in standard organic Google Search results. Publishers can opt out of AI features while remaining fully indexed in traditional search.
Does the opt-out work for the Gemini app?
No. The opt-out toggle only covers AI Overviews, AI Mode in Search, and AI Overviews in Discover. It explicitly excludes the Google Gemini app, which operates under separate terms. Publishers cannot currently block their content from Gemini through Search Console.
When does the Google AI opt-out become enforceable?
The opt-out became available for testing on June 3, 2026, but enforcement begins June 17, 2026. Google is currently testing the feature with a subset of UK publishers. A global rollout is planned for after the UK testing phase.
Why did Google create the AI Overviews opt-out?
Google created the opt-out to comply with a binding order from the UK’s Competition and Markets Authority (CMA), the first such regulatory requirement imposed on Google for AI search. The CMA mandated the feature under the Digital Markets, Competition and Consumers Act 2024, which gives UK regulators new enforcement powers over dominant digital platforms.
