Publishers can now block their content from Google AI Overviews

Britain’s Competition and Markets Authority just pulled off what it’s calling a world first. Google now has to let publishers yank their content out of AI Overviews, AI Mode, and the rest of its generative search lineup.

Google rolled out the new control on Tuesday as part of a bigger set of tools for site owners. The CMA says the opt-out gives publishers leverage when they negotiate licensing deals with Google.

Publishers and site owners can stop Google’s AI search

Publishers can flip the toggle, and their site stops showing up in Google’s generative AI products. The website will no longer be part of AI Overviews, AI Mode, or AI Overviews in Discover.

The content won’t get used to generate those AI responses either. Google says the opt-out won’t touch websites’ rankings in regular search results.

The feature goes live first with a small batch of UK publishers. Google plans to roll it out globally after testing. Google’s also adding performance data to Search Console.

Publishers will see impression counts for their pages inside AI responses, broken down by page and country. Google will add more metrics later based on what publishers ask for.

The regulator designated Google as having “strategic market status” back in October 2025. That classification handed the CMA the authority to impose rules on how Google operates.

In January 2026, the CMA told Google to give publishers a choice and let them decide if their content gets pulled into AI search features or used to train standalone AI models.

“Today, we have introduced a world first requirement on Google’s search services in the UK, enabling fair treatment, greater transparency and meaningful choice for businesses and consumers. With features like AI Overviews rapidly reshaping online search, it is crucial that content publishers, including news organisations, have appropriate bargaining power over how their content is used,” said Sarah Cardell, CMA chief executive.

Google shares AI mode usage numbers

Google dropped usage figures alongside the opt-out announcement.

AI Overviews hits more than 2.5 billion monthly active users. AI Mode just passed one billion. Those numbers put publishers in a spot, because opting out means walking away from all that traffic and visibility.

Google’s new Search Console metrics play the same role. Publishers can now see exactly how much reach they’re getting from AI search. Any website owner weighing the opt-out will have data showing what they’d be giving up.
