CMA Orders Google to Let Publishers Opt Out
The UK Competition and Markets Authority (CMA) has imposed conduct requirements on Google that allow publishers to opt out of appearing in Google AI Overviews and require clearer attribution with direct links for publisher content used in AI-generated search responses. The measures follow Google's designation with Strategic Market Status in search services and respond to publisher concerns after the May 2024 launch of AI Overviews, which some publishers say caused steep declines in click-through rates. Google has nine months to implement the controls (with key parts expected sooner) and must publish compliance reports every six months during the first year. Google is testing a Search Console toggle to let site owners manage AI Overview inclusion; the rules apply only in the UK.
Regulatory intervention forces a major platform (Google) to give publishers opt-out and attribution controls for AI search features in the UK, affecting publisher traffic, search attribution, and setting a precedent for oversight of generative search — material for publishers, advertisers and platforms.

UK Orders Google to Allow Publisher AI Opt-Out
The UK Competition and Markets Authority (CMA) has ordered Google to give UK publishers the ability to opt out of having their content used in Google’s AI search features without removing their sites from general Google Search. The mandate requires controls that separately cover use for model training (including fine-tuning) and grounding of AI outputs, and allows domain- or page-level opt-outs. Google is prohibited from penalising publishers’ search rankings for opting out. The company has nine months to implement the measures and must publish regular compliance reports. Google says it is already testing grounding controls with a subset of UK site owners and may roll out more broadly. Industry group Movement for an Open Web criticised the nine-month timeline as too slow.
Publishers can opt out of Google AI Search
The U.K. has enacted rules requiring Google to provide website publishers with a way to opt out of being aggregated into its generative AI search features. Google announced compliance and will add a toggle in Search Console that, when enabled, excludes a publisher’s site from AI Overviews, AI Mode and AI Overviews in Discover. The feature will be tested with a subset of U.K. publishers before a global rollout. The Competition and Markets Authority (CMA) called the measure a “world first,” saying it strengthens publishers’ negotiating position for content use and training. Google must also ensure clear attribution links in AI responses and says opting out will not affect traditional search ranking. Google will add new Search Console metrics showing which pages appear in AI responses and in which countries.
Google AI opt-out leaves publishers with unusable choice
The U.K. Competition and Markets Authority (CMA) has ordered Google to give publishers greater control and transparency over how their content is used in AI search—including opt-outs from AI Overviews, AI Mode, AI summaries in Discover, clearer attribution, reporting, and an opt-out from model training. Google says it will roll out an opt-out toggle globally via Search Console and has nine months to implement changes. Publishers and industry figures warn the remedy is effectively unusable: the system is default opt-in, Google is not providing AI-specific click data necessary to judge impact, and multiple services may be bundled under a single toggle. Many publishers fear they will remain opted in due to competitive pressure and lack of granular reporting. The CMA says it will monitor implementation and may take further action if necessary.
