London, UK - April 6, 2026 – The UK's Competition and Markets Authority (CMA) has formally imposed a 'publisher conduct requirement' on Google's general search services, demanding significant changes to how the company handles publisher content, particularly concerning its use in generative AI features. This regulatory move mandates that Google must offer publishers effective controls over the utilization of their content for AI training and provide clear metrics on user engagement within AI-driven search results. The rules, officially enacted on June 3, 2026, aim to address concerns about transparency, attribution, and publisher control in the evolving landscape of search technology.
Google has been given a nine-month window to fully implement these requirements. The core of the new regulation targets the increasing use of web content to fuel Google's AI-powered overviews, a feature that has drawn criticism from publishers who report a significant drop in website traffic. The CMA's decision allows publishers, including news organizations, the explicit option to opt out of having their content used to train Google's AI models and appear in these prominent AI-generated summaries at the top of search results.

Publishers Given Levers on AI Content Usage
Google is now compelled to provide publishers with clear and detailed metrics concerning user interaction with their content specifically within generative AI search functions. Furthermore, the company must take reasonable steps to ensure accurate and clear attribution of search content and offer users straightforward ways to access the original source material. A commitment has also been made by Google to publish easily understandable information detailing its attribution practices.
Mrinalini Loew, general manager of Google's Search Ecosystem, indicated that the company is already testing new controls allowing website owners to manage their content's appearance in generative AI features. She stated, "Website owners can decide if they want their site to appear in and help ground responses in our generative AI Search features." Google is also rolling out new data insights for website owners, detailing page impressions and the visibility of their content within AI responses globally. These measures are intended to empower publishers, potentially strengthening their negotiating position for content deals with Google.

Broader Regulatory Framework Takes Shape
The 'publisher conduct requirement' is part of a larger regulatory initiative by the CMA under the UK's digital markets competition regime. The authority had previously designated Google as having 'strategic market status' in respect of its general search and search advertising services in October 2025. While the publisher requirement is now finalized, decisions on other proposed conduct requirements, also put forth for public consultation, are expected to follow.
The CMA's broader aims include ensuring fairness and transparency in how Google ranks search results, encompassing AI-generated content. Proposals also touch upon giving businesses more control over their search data and facilitating better use of that data for personalized benefits. This comprehensive approach signals a concerted effort by UK regulators to shape the competitive landscape and ensure fairer practices within the digital search market, particularly as AI integration accelerates.
