UK regulators mandate Google enhance AI search attribution and publisher opt-outs

The UK Competition and Markets Authority has issued a binding order requiring Google to implement clearer attributions and links for publisher content within its AI-generated search features, specifically AI Overviews. Google must provide publishers with effective tools to opt out of having their content used to power AI features, including at the directory and page levels. The regulator has prohibited Google from penalising, downranking, or reducing traffic to publishers that choose to opt out.

Google has agreed to comply with the ruling and must submit an implementation plan within one month, with full compliance required within nine months. In response, the company is currently testing new controls in Search Console for a subset of UK website owners, allowing them to manage how their content appears in generative AI search features. These new controls include metrics on impressions and information on which pages appear in AI responses and in which countries.

The CMA rejected Google’s previous arguments that page-level opt-outs would increase crawling costs or cause user confusion, stating there is no evidence to support such claims. Google had previously argued that users do not want "lots of sources" and that excessive attribution could worsen user experience. However, the regulator determined that Google holds "strategic market status" in general search services, which allows it to impose these conduct requirements.

The News Media Association described the ruling as a significant step towards leveling the playing field and called for robust enforcement. The CMA also noted that it is conducting ongoing investigations into Apple and Microsoft regarding similar issues. Google stated that its recent announcements regarding additional links to web content in AI search results apply globally, though it did not confirm if the specific UK-mandated attribution changes will be rolled out globally.

The CMA requires Google to publish compliance reports supported by key data and metrics to explain how it has met the new requirements. The regulator emphasized that transparency over attribution is important so that publishers can trust that their content is sufficiently and accurately attributed, which also helps end users understand how Google has attributed responses.
