Google’s AI Visibility Push Complicates Publisher Opt-Outs

By Tom Whitfield

Google must provide U.K. publishers with click data by Dec. 3, the measure they need to judge whether appearances in Google’s AI search features send traffic or replace it.

What changes on Dec. 3?

The Competition and Markets Authority (CMA) imposed its first conduct requirement on Google over the summer. The requirement covers click data showing whether content displayed in AI features sends readers to publisher sites.

Google has shown regulators and publishers that it is cooperating by sharing impression data: how often publisher content appears in AI features. Chris Dicker, CEO of Candr Media, which owns Trusted Reviews, said: “That is the metric that will determine whether they [publishers] turn it off or not.” Dicker said Google could have released click data with impressions but had not.

Although the CMA ruling applied only to the U.K., Google opened the opt-out to sites worldwide on August 31. Publishers can use the Search Console control to exclude content from Google’s AI features. Publishers hope Google will extend click reporting worldwide. Google has not confirmed that plan, despite opening the control globally.

Google must deliver page-level grounding controls by March 3, 2027. Publishers still cannot exclude individual AI features, so any decision applies across the bundle.

The missing traffic data will drive the next round of testing.

Why does Google’s AI visibility make opt-out harder?

Google has updated AI Mode and AI Overviews to show links more often and more prominently. The company has added timely article carousels, related-story links and more context around surfaced articles.

Google says those changes will help publishers track, control and increase content visibility. It is also testing links from video creators’ and publishers’ names to their Search profiles.

Google says Preferred Sources, which lets users bookmark favored websites and publishers, has grown sevenfold this year. As those surfaces become more valuable, Google’s expanded AI placement gives publishers a stronger reason to remain visible than to opt out.

The Daily Mail is discussing the CMA controls, according to Carly Steven, its director of ecommerce and commercial editorial. At Digiday’s Media Strategies London event in October, she said the group must balance URL-level removal with continued presence on the surfaces where users search.

Google is making its AI surfaces more valuable at the same time it gives publishers more control over removal.

What will publishers test before making a decision?

Chris Dicker expects Google to release click data in the coming weeks, ahead of Black Friday. He said publishers are holding off on the controls because they do not want to remove a large proportion of their activities during a crucial sales period.

Reuters Digital’s Phil Andraos told Digiday in June that the lack of click data would slow any decision and make testing likely. Josh Muncke, vp of generative AI at The Economist Group, said he did not believe the group had tested the control yet, though it was examining it.

Muncke said The Economist Group’s decision will depend on two measures: traffic from Google and the frequency of its name in top AI answers, even when users do not click. He also described broader visibility as a second-order effect of switching features off.

“It will be a case more of thinking about where and how we can test, measure, and see the impacts, and make kind of like more structured, data-driven calls as we go,” Muncke said.

Muncke expects staged testing rather than one fixed decision.

Can publishers opt out of individual AI features?

No. Google’s controls bundle AI Mode, AI Overviews and other AI features, preventing feature-by-feature withdrawal. The Professional Publishers Association (PPA) is appealing to the CMA to unbundle them and give publishers deeper control.

Eilidh Wilson, the PPA’s head of policy and Public Affairs, said publishers’ main concern is an all-or-none choice. She said the PPA agreed to a further briefing with the CMA on separating the features.

The PPA’s example is that an AI Overview can replace a click a publisher previously received, while the same content may remain useful in a broader conversational AI search. The proposed change would let publishers preserve that second use while declining the first.

Digiday reported that some publishers expect excluded sites to drop out of the Top Stories carousel inside AI Overviews. Google has not said how its control treats that unit.

Feature-level control remains the publishers’ main unresolved demand.

Will Google send enough traffic to preserve the exchange?

David Buttle, founder of publisher AI standards coalition SPUR, believes Google prefers enough referral traffic from AI surfaces to persuade publishers to consent voluntarily, rather than paying each time it uses their content. He said that exchange requires Google to keep returning value.

Buttle said ChatGPT generally does not pay for content and does not send traffic away. He said Google tries to intermediate as many clicks from Discover as possible, an important publisher traffic source where Google serves summaries aggressively. Google bundles that Discover control with controls for summaries elsewhere.

Buttle expects publishers to remain unlikely to opt out unless Google grants more granular controls. He said Google could adjust the Discover interface to increase AI-mediated referrals, making the decision to opt out harder.

Google’s case rests on referrals, while its Discover strategy gives publishers more reason to leave.

The next checkpoint is the U.K. click data due by Dec. 3. Publishers will use those numbers to decide whether and where to test opt-outs, while the PPA presses the CMA for feature-level control.
