UK Regulator Forces Google to Let Websites Opt Out of AI Overviews: What It Means for Your Business

Britain's Competition and Markets Authority on 28 January 2026 proposed that website publishers be allowed to opt out of having their content used in Google's AI Overviews and AI Mode, without losing visibility in traditional search results. The conduct requirements, published under new powers in the Digital Markets, Competition and Consumers Act 2024, mark the first time a UK regulator has imposed binding conditions on how Google operates its search services.

The proposals go further than content opt-outs. The CMA is also requiring Google to demonstrate that it ranks search results fairly, including in AI Overviews and AI Mode, and to provide proper attribution when AI features use publisher content. A public consultation runs until 25 February 2026.

Google controls over 90% of online searches in the UK and generates at least £20 billion annually from UK advertisers. It is the first tech platform to face conduct requirements under the new regulatory framework.

What the CMA Is Proposing

The conduct requirements cover four areas, all aimed at limiting Google's ability to use website content in AI features without consent or compensation.

Publisher opt-out controls. Google must provide "effective controls" allowing publishers to withhold their content from being used to train broader generative AI services and from powering AI Overviews and AI Mode. Critically, these controls must not penalise publishers in traditional search rankings. Google must also ensure these controls "evolve appropriately as generative AI services and features develop."

Fair ranking. Google must demonstrate to the CMA that it ranks results using "objective and non-discriminatory criteria" (relevance, quality, and user context) and does not favour its own properties or commercial partners. This applies to traditional results, AI Overviews, and AI Mode.

Transparency and attribution. Google must publish clear information about how it uses website content across its generative AI services and take practical steps to ensure publisher content is properly attributed in AI results.

Search engine choice screens. Android devices and Chrome browsers must present users with a meaningful choice of default search engine, making it easier to switch away from Google.

"These proposed actions would give UK businesses and consumers more choice and control over how they interact with Google's search services," said CMA chief executive Sarah Cardell. She added that the proposals would "provide a fairer deal for content publishers, particularly news organisations."

Why Current Opt-Out Tools Don't Work

The CMA's proposals address a specific gap that has frustrated publishers for over a year. The existing tools do not let websites selectively control how their content appears in AI features.

Google-Extended blocks content from training Gemini and Vertex AI models but has no effect on whether content appears in AI Overviews or AI Mode. A site using Google-Extended can still have its content summarised without consent.

Nosnippet and max-snippet directives do affect AI Overviews, but they also eliminate traditional search snippets entirely. According to research cited by Google, using nosnippet reduces search traffic by approximately 45%. Publishers face a punishing trade-off: block AI summaries and lose nearly half your search visibility, or accept AI summaries and lose control of how your content is presented.

Google's principal product manager Ron Eden acknowledged the limitation, stating the company is "exploring updates to our controls to let sites specifically opt out of Search generative AI features." He cautioned that "any new controls need to avoid breaking search in a way that leads to a fragmented or confusing experience for people."

A Cloudflare analysis of AI crawler compliance found that 72% of UK websites have AI bots violating their robots.txt directives, suggesting that even when publishers try to control AI access, the current mechanisms are not reliably enforced.

What This Means for UK Small Businesses

Most coverage of the CMA's proposals focuses on news publishers. That is understandable: AI Overviews have reduced global search referrals to news sites by 33% according to Chartbeat data covering over 2,500 outlets, and Ahrefs research shows AI Overviews cut click-through rates by 58% overall. But the proposals apply to all websites, and the implications for UK small businesses are different from those for publishers.

For news publishers, the opt-out is defensive. They lose revenue when Google summarises their articles in AI Overviews because readers get the information without clicking through. Their business model depends on visits.

For most small businesses, the equation is reversed. A plumber, accountant, or web designer benefits from being cited in AI Overviews because the citation acts as a recommendation. When someone asks Google "best web designers in Kettering" and the AI Overview cites your business, that is visibility you would not have had in a traditional list of ten blue links.

The risk for small businesses is not that Google is using their content; it is that Google is not using it at all. When we tested 100 UK small businesses for AI visibility, 97 had no AI discovery files. The average visibility score was 31 out of 100. These businesses are invisible to the AI systems that increasingly mediate how customers find services. Our GEO for WordPress guide covers how to structure your site for AI citation step by step.

"The CMA rightly recognises that Google is able to extract valuable data without reward, harming publishers and giving the company an unfair advantage over competitors in the AI model market, including British start-ups."

- Owen Meredith, Chief Executive, News Media Association, NMA Statement

The practical action for most UK small businesses is not to prepare to opt out. It is to ensure they are opted in effectively. That means structuring website content so AI systems can cite it accurately, a discipline now called Generative Engine Optimisation (GEO), implementing AI discovery files that tell AI crawlers who you are and what you do, and monitoring how AI systems describe your business using tools like the AI Visibility Checker.

The Bigger Picture: Regulation Meets Reality

The CMA's proposals arrive amid a broader regulatory push. Just days earlier, the European Commission opened DMA proceedings requiring Google to share search ranking data with rival AI platforms. The US Department of Justice and South African Competition Commission have pursued similar actions. Google's dominance of search is being challenged from multiple directions simultaneously.

Not everyone believes the CMA has gone far enough. Tim Cowen, co-founder of the Movement for an Open Web, wrote that the proposals "fall well short of the mark," arguing that "opting out of AI Overviews in the future won't change" the traffic and revenue publishers have already lost. He advocated for unbundling and direct compensation.

The Professional Publishers Association acknowledged the proposals as "a major step forward" but noted that "opt out is an essential safeguard, but it doesn't resolve the wider value exchange question. AI Overviews still replace clicks in many contexts, and without a clear model for licensing, the commercial imbalance remains."

Jamie MacEwan, senior analyst at Enders, highlighted the pace mismatch: "It just goes to show how slow the regulatory process is compared to tech companies' ability to iterate and transform their products at speed." Google's recent Gemini 3 upgrade to AI Overviews for over one billion users happened in a single day. The CMA's consultation alone takes a month.

Publishers are already taking matters into their own hands. A BuzzStream study found 79% of top news publishers block at least one AI training bot, with 71% blocking retrieval bots that affect AI citations. They are "voting with their robots.txt files," whether regulators act or not.

What to Watch: The 25 February Deadline

The CMA's consultation closes at 5pm on 25 February 2026. Responses can be submitted via the CMA Connect portal or by email to searchsms@cma.gov.uk. Any business affected by how Google uses their content in AI features can respond.

After the consultation, the CMA will issue a final decision on the conduct requirements. The timeline for Google's implementation has not been specified, but the company has already signalled willingness to develop new controls, likely wanting to shape the mechanism rather than have one imposed.

Three things to monitor:

What the new opt-out mechanism looks like. Google has said it is "exploring updates" but provided no technical specifics. The design of the control (whether a robots.txt directive, a Search Console toggle, or something else entirely) will determine how practical it is for businesses to use.

Whether fair ranking requirements have teeth. The CMA wants Google to prove its ranking is non-discriminatory. Whether the regulator has the technical capacity to verify this, and what penalties apply for non-compliance, remain unclear.

How this interacts with AI Mode's expansion in the UK. Google's AI Mode conversational search is available through Search Labs and expanding. As more users shift from traditional search to AI-mediated conversations, the question of who controls content use in those conversations becomes even more consequential.
