Opting out of Google AI Overviews: what the UK's new rules protect from Dec. 3, 2026

Any site can already opt out of Google's AI answers in Search. Search Console's Search generative AI control has been available worldwide since Aug. 31, 2026, and Google says the choice isn't a ranking signal for the rest of Search. From Dec. 3, 2026, the UK Competition and Markets Authority makes the key protections a legal duty for content shown to people in the UK: Google may not downrank or otherwise disadvantage content that opts out, must give publishers engagement data including clicks and click-through rate, and must take reasonable steps to attribute sources clearly. A page-level control follows by March 2027. Opting out removes your links and words from AI Overviews, but not the answer, which Google says can still draw on other sites' content that "may appear similar to yours". This guide covers what changes on Dec. 3, who is covered, what each Google control does, and who should consider opting out, as of Oct. 27, 2026.

Direct answer

You don't have to wait for Dec. 3 to opt out. Google's Search generative AI control in Search Console lets any site exclude its links and content from Google's AI features in Search, and Google rolled it out "to all websites worldwide" on Aug. 31, 2026. Google also says the control "isn't used as a ranking or inclusion signal affecting other parts of Search".

What Dec. 3, 2026 changes is the legal footing. Under the UK's publisher conduct requirement, imposed on June 3, 2026, Google must not penalize publishers for using the controls, "for example by downranking their Search Content", for content shown to people in the UK. It must also provide engagement data, including clicks and click-through rate, and take reasonable steps to attribute content clearly. A page-level control for grounding follows three months later.

For most brands, opting out is the wrong move. It removes your links and your words from AI Overviews, but the answer still gets written from other sites, and you also lose the "preferred" badge in AI answers. It can make sense for publishers whose content gets summarized in place, ideally tested on one directory first, once the click data arrives.

What changes on Dec. 3, 2026, and what doesn't

The CMA's summary is explicit: "Google has until 3 December 2026 to comply with the CR, with an additional 3 months to develop and roll-out a page level control." The legal notice says the same: it comes into force six months after June 3, 2026, except the page-level control, which comes into force after nine months. The table compares what exists today with what the rules require.

	Today (worldwide)	From Dec. 3, 2026 (content shown in the UK)
Opting out of AI features in Search	The Search generative AI control in Search Console, set per property (a whole site, a subdomain, or a directory such as /blog/)	Required: controls to withhold content from grounding Google's AI features in Search, at directory level; page level by March 2027
No downranking for opting out	Google's own statement that the control isn't a ranking signal	Binding: no downranking or other disadvantage in general search, and no loss of features such as snippets
Engagement data	Impressions only, in Search Console's generative AI report	Impressions, clicks, and click-through rate, separate from organic results, through a platform such as Search Console
Attribution	Google's own design choices	Reasonable steps to attribute content clearly and accurately, plus published explanations of how
Training	Google-Extended limits training of Gemini models, which Google's help page says includes the models behind its AI features in Search, and grounding in the Gemini app and Vertex AI	Controls must cover training as well as grounding, for Google's AI features in Search and its broader AI services

Who is covered: content shown in the UK, not just UK sites

The rules apply to "the outputs of all generative AI services and features shown to any natural or legal persons located in the UK", and the CMA's interpretative notes say location can be taken from "the location reported by their device". So a US brand whose content appears in AI Overviews for people in the UK is covered for those answers, and a UK site's content shown to people elsewhere is not.

"Publisher" is broad. The legal notice defines it as "any party that makes content available on the web", which includes brands and B2B companies, not only news outlets. The CMA says "all publishers will benefit to the extent that their Search Content is used in the outputs" shown to UK users. Google may also choose to apply the same approach more widely, but it hasn't announced how it will implement the UK rules.

"Without being downranked": what the rules actually protect

The core text is paragraph 9 of the legal notice: Google "shall not seek to prevent publishers from, or penalise them for, using the controls … for example by downranking their Search Content, or otherwise disadvantaging them, relative to opted-in Search Content, in general search outside of search generative AI features." The interpretative notes add that opting out "should therefore not lead to a publisher losing features such as snippets".

Two limits are written into the same notes. The CMA "recognises that Google may not be able to control for all possible second order effects of the controls on Google's overall ranking algorithm", so the protection is against deliberate penalties, not against every ripple. And Google may still promote the benefits of staying in, or negotiate an agreement with a publisher about its use of the controls.

Outside the UK, you rely on Google's own statement that the control isn't a ranking signal. That is a policy, not a legal duty.

The four controls, and what each one does

Google offers four different levers, and they are easy to confuse. Only the first is built for AI Overviews specifically. For a fuller guide to crawler and training settings, see AI crawler access: search, agents, and training.

Control	What it does	Cost
Search generative AI control (Search Console)	Excludes a property's links and content from Google's AI features in Search, including AI Overviews, and from grounding their answers	No traffic or impressions from those features; per property, not per page
nosnippet, max-snippet, data-nosnippet (robots meta tags and attributes)	Stops or limits a page's text being shown in results or used as a direct input for AI Overviews; data-nosnippet works on parts of a page	Also removes or shortens your snippet in ordinary search results
Google-Extended (robots.txt)	Limits training of Google's Gemini models and grounding in the Gemini app and Vertex AI	Doesn't control whether you appear in AI Overviews; Google says it doesn't affect inclusion in Search
noindex	Removes a page from Google Search entirely	Removes the page from ordinary results too

What opting out removes, keeps, and doesn't touch

Google's help page for the control is specific about the trade, and it is worth reading before you change the setting.

It removes your links and content from the AI answer. Excluded sites aren't linked to within these features, their content isn't used to ground the answers, and Google says "You won't receive any traffic or impressions from these features."
It doesn't remove the answer. "Content from other sites will still be available in those features, and it may appear similar to yours." For a brand, that means competitors, reviewers, and roundups can still shape what AI Overviews says about your category, and about you.
It removes the preferred badge. Google's Preferred Sources documentation says that to be highlighted as a preferred source in AI answers, "you must make sure your site is included in Search generative AI features in Search Console."
It shouldn't cost you ordinary rankings. Google says the control isn't a ranking signal for other parts of Search, and from Dec. 3 the UK rules bar Google from downranking opted-out content shown in the UK, short of indirect effects the CMA says Google may not be able to control.
It doesn't change AI training. Google's help page says the control "doesn't affect AI training"; Google-Extended is the training control. It also notes your content "may still be used to power Google Search as a whole".

Should you opt out? Publishers and brands differ

The rules are framed around publishers, and they matter most for sites whose content is summarized in place, where an AI answer can replace the visit. For a site like that, opting out is a business decision worth testing. A sensible order, based on what the rules provide: wait for the click data the CMA requires, exclude one directory first by setting the control on a URL-prefix property such as /guides/, then compare traffic and classic positions in Search Console before going further.

For a brand that wants to be named and recommended, opting out mostly hands the answer to other sources. AI Overviews can still answer "best X for Y" and "is [your brand] any good", built from pages you don't control, and your own site can no longer be the cited source or carry the preferred badge. If your concern is that the answer is wrong, the fix is usually on your pages and in the third-party sources the answer cites, not in leaving.

The data you'll get, and won't

Today, Search Console's generative AI performance report shows impressions only: no clicks, no click-through rate, and no queries. The CMA's interpretative notes expect Google to provide impressions, clicks, and click-through rate for content shown in its AI features in Search, "fully disaggregated from other elements of general search", through a platform such as Search Console, plus a way to identify those clicks so you can judge their quality. The data may be aggregated across features rather than split by feature, and query-level data isn't on the list. For what each free report shows today, see what Search Console, Bing, GA4, and Merchant Center show.

Google hasn't said what the report will look like on Dec. 3 or whether the new data will cover only content shown in the UK. And because query-level data isn't on the CMA's list, the practical way to see which of your pages AI Overviews cites, and for which questions, is to run the questions yourself.

What's next

Dates to watch, as of Oct. 27, 2026.

Choice screens: on Sept. 23, 2026, the CMA proposed that Google show Android and Chrome users a choice of search services, including AI assistants, but only providers that attribute publisher content clearly. Responses closed Oct. 9, and the CMA expects a decision by the end of 2026. It is still a proposal.
Jan. 3, 2027: Google's first compliance report to the CMA is due, covering June 3 to Dec. 3, 2026.
The EU: the European Commission opened an investigation on Dec. 9, 2025 into whether publishers can refuse the use of their content in Google's AI features "without losing access to Google Search", and under the Digital Markets Act, AI chatbots with search functions can receive shared Google search data from January 2027.
March 2027: the page-level control for grounding Google's AI features in Search is due.

FAQ

Can I opt out of Google AI Overviews without hurting my rankings?

Google says its Search generative AI control isn't a ranking signal for the rest of Search, and from Dec. 3, 2026 the UK's rules make that binding for content shown to people in the UK: Google may not downrank or otherwise disadvantage opted-out content, or take away features such as snippets. The CMA notes that Google may not be able to control every indirect effect on its ranking systems.

When do the UK CMA rules on Google's AI answers take effect?

On Dec. 3, 2026, six months after the CMA imposed them on June 3, 2026. The page-level control for grounding Google's AI features in Search follows three months later, by March 2027.

Does the UK opt-out rule apply to sites outside the UK?

It applies to content shown to people located in the UK, wherever the site is based. A US brand's content in AI Overviews for UK users is covered; a UK site's content shown to users elsewhere is not.

Does blocking Google-Extended remove my site from AI Overviews?

No. Google-Extended limits training of Gemini models and grounding in the Gemini app and Vertex AI, and Google says it doesn't affect inclusion in Search. The control for AI Overviews is the Search generative AI control in Search Console.

Will Search Console show clicks from AI Overviews?

Not separately, yet. The generative AI report shows impressions only, and clicks on AI Overview links count in the standard Performance report alongside ordinary web results. The CMA expects Google to provide clicks and click-through rate for content shown in its AI features in Search, but Google hasn't announced how or when.

If I opt out of AI Overviews, does Google stop answering questions about my brand?

No. Google says content from other sites will still be available in those features, "and it may appear similar to yours." Opting out removes your links and words from the answer, not the answer itself.
