The UK's Competition and Markets Authority has ordered Google to give publishers control over whether their content appears in AI search features like AI Overviews. The ruling also requires clearer attribution and links to publisher content in AI-generated search results, marking a world-first requirement that aims to strengthen publishers' bargaining power for content deals.

UK Publishers Gain Control Over Google AI Search Features

The Competition and Markets Authority has imposed legally binding requirements on Google AI search, forcing the tech giant to give UK publishers unprecedented control over how their content appears in generative AI features. The CMA ruling mandates that publishers can now opt out of AI search tools like Google AI Overviews, AI Mode, and AI Overviews in Discover, marking what regulators call a "world-first" intervention in the rapidly evolving AI search landscape

The new requirements address growing concerns from news organizations and website owners who have reported significant traffic declines since Google began prioritizing AI-generated summaries at the top of search results. An August survey from Digital Content Next found that median year-over-year referral traffic from Google Search dropped 10% in May and June 2025, with some publishers experiencing click-through rates declining by up to 25%

. By allowing publishers opt out of AI search features, the CMA aims to put them "in a stronger position to negotiate content deals with Google," according to the regulator's announcement

Google Must Provide Clearer Links in AI Search Results

Beyond opt-out controls, the CMA ruling requires Google to ensure proper attribution of publisher content using clearer links in AI-generated search results. This addresses concerns that Google AI Overviews often deliver confident-sounding responses to search queries without clearly indicating which sources support those claims

Google had previously opposed what it termed "excessive attribution" in its formal response to the CMA proceeding in February, arguing that it was "already motivated to strike the right balance between attribution and usability." The company warned that "excessive attribution of lots of sources may worsen the user experience and lead to fewer clicks," while acknowledging that "too little attribution and publishers may decide to opt out, depriving Google of their content"

. Despite these objections, Google has now committed to full compliance and says it is "continuing to experiment with a range of new link designs in our AI experiences to make them more useful."

New Google Search Console Controls Roll Out

In response to the CMA ruling, Google has begun testing new controls through the Search Console that allow website owners to manage how their content appears in AI search features. The new toggle lets publishers decide whether they want their sites to appear in and help ground responses in generative AI Search features

. Crucially, the CMA ruled that Google cannot penalize publishers for opting out, meaning the company cannot downrank opted-out publishers in general search rankings outside of AI features

Website owners will also receive enhanced data through Google Search Console controls, including impressions metrics and information about which pages appear in AI responses and in what countries

. These features are currently rolling out to a subset of website owners in the UK for testing before expanding globally. Sites that opt out will not receive traffic or impressions from generative AI features, but Google has confirmed this control will not affect search rankings for traditional search results

Implications for Content Deals and AI Models

The CMA ruling also prevents Google from using opted-out content for fine-tuning its AI models, giving publishers additional leverage in negotiations

2

. News Media Association CEO Theo Bamber called the legally enforceable conduct requirements "a significant step towards leveling the playing field and building a fair, transparent digital economy where premium content is properly respected and fairly compensated"

. However, he emphasized that success depends on "efficient implementation, robust enforcement and the ability to adapt and strengthen the rules if they are not working properly."

Google has nine months to comply with all requirements, though the CMA expects important parts of the controls to become available well before that deadline

1

. The company will be required to submit and publish compliance reports with key data and metrics explaining changes made. CMA Chief Executive Sarah Cardell stated that the regulator is "actively monitoring how Google is implementing these changes -- including assessing the implications for businesses" following Google's announcement of major search box upgrades at I/O last month

3

. The CMA retains the power to bring forward additional measures to ensure fair exchange of value between Google and publishers as the situation evolves, signaling that this may be just the beginning of regulatory oversight in AI search. The regulator's focus on consumer trust and market dominance reflects broader concerns about how tech giants leverage content from news organizations and other publishers to power their AI tools without adequate compensation or attribution.
