Google AI Overviews Opt-Out Hits Search Console: Gemini Excluded as Publishers Weigh Trade-Offs

For the first time in the AI search era, online publishers can tell Google to keep their content out of its AI-generated summaries without disappearing from conventional search results — but the control that makes this possible will not take effect until June 17, and it does not reach Google's Gemini app at all.

The UK's Competition and Markets Authority issued a legally binding conduct requirement on June 3 ordering Google to give publishers genuine opt-out controls over AI Overviews, AI Mode, and related AI-powered features. Google responded the same day by launching a new toggle inside Search Console — a free tool that lets website owners manage their presence in Google's search results — giving a subset of UK publishers the ability to block their content from appearing in AI Overviews and AI Mode. The toggle also covers AI Overviews in Google Discover. Google says the opt-out setting will not affect a site's ranking in regular search, and it plans to extend the feature to publishers globally after the UK testing phase.

The catch: Google said the setting becomes active on June 17. Publishers who flip the switch before that date are not yet protected.

Eighteen Months of Forced Consent

The CMA's intervention ends what publishers had called a coercive arrangement lasting roughly eighteen months. Since Google rolled out AI Overviews at scale, the only mechanism available to publishers who wanted to withhold their content from AI-generated answers was to block Google's crawlers entirely — a step that would have removed their sites from conventional search results as well. Because Google controls more than 90% of general search queries in the UK, that option was not realistic for any publisher dependent on search referrals.

Penske Media, parent company of Rolling Stone, Billboard, and Variety, sued Google in September 2025 over the arrangement, alleging affiliate revenue had dropped by more than a third from its peak by late 2024. Pew Research data showed that only 8% of Google users whose search returned an AI Overview clicked on an underlying link — compared to 15% when no AI Overview appeared. Chartbeat data covering more than 2,500 publishers found Google referrals had fallen by roughly a third across the board. Business Insider saw its organic search traffic fall 55% over three years and cut 21% of its staff in May 2025. Press Gazette tracked more than 3,400 journalism job cuts across the United States and United Kingdom in 2025 alone, with 2026 already running ahead of that pace.

The Independent Publishers Alliance filed antitrust complaints with both the European Commission and the CMA, arguing Google was misusing web content to power AI summaries while eliminating any meaningful way for publishers to say no.

How Google AI Overviews Work — and Why Opt-Out Is Technically Complex

Google AI Overviews use a technique called Retrieval-Augmented Generation, or RAG. When a user submits a search query, Google's system retrieves relevant pages from its live search index and feeds that content into its Gemini large language model as source material. Gemini then generates a summary answer grounded in those retrieved pages, with links back to the sources. The CMA's opt-out requirement targets this retrieval step directly: a publisher who toggles out of AI features tells Google's system to exclude their pages from the pool of source material used in that generation process.

The fine-tuning provision in the CMA's order addresses a separate pipeline. Beyond generating real-time answers, AI companies also use web content to update the underlying weights of their language models — a process known as fine-tuning, which permanently shapes how the model responds to future queries. Under the order, publishers can block their content from both uses: real-time grounding in AI Overviews and AI Mode, and longer-term fine-tuning of Google's models.

The Gemini exclusion matters precisely because of this architecture. Google's Gemini app runs on the same underlying model but operates through a different product surface and inference pipeline from Google Search. Under the CMA's order and Google's Search Console toggle, opting out of AI Overviews does not prevent a publisher's content from surfacing inside the Gemini app — a limitation that several publishers and privacy advocates flagged during the consultation period that preceded the order.

A senior Google executive described building these publisher controls as "a huge engineering project" at a conference in February 2026, specifically because the challenge was not blocking content from Google Search entirely, but rather blocking it from AI-generated features while keeping those pages indexed and ranked normally in conventional results. Google's Search Console mechanism addresses that challenge — publishers retain their regular search presence — but the scope of what it actually covers remains narrower than the full range of AI-powered products that use Google's model and index.

What the Google Search Console AI Toggle Covers and What It Skips

The new toggle, accessed through Search Console settings, blocks a publisher's content from appearing in AI Overviews, AI Mode, and AI Overviews in Discover. Google confirmed that activating the setting will not be used as a ranking signal in conventional search results. Publishers who opt out will lose impressions and traffic from the AI-powered features but retain their standard organic rankings.

The toggle also comes with a new Generative AI performance report inside Search Console, showing publishers impression data and which pages are surfacing in AI-generated responses — metrics that were not previously available.

Three limitations define the toggle's current scope. The Gemini app is explicitly carved out: the CMA's order applies to Google's search products, and Google's implementation reflects that boundary. A publisher who opts out of AI Overviews may still find their content appearing in Gemini responses. The opt-out also does not retroactively remove content already embedded in model weights; the fine-tuning restriction applies going forward. And Google retains the ability to use content from open-source datasets even where a publisher has opted out, provided that content was obtained legally — the CMA included an anti-circumvention clause to prevent Google from paying a third-party crawler to gather opted-out publisher content, but the open-source exception remains.

Do Publishers Actually Gain From Opting Out?

The Professional Publishers Association called the order a meaningful step but made clear the math does not work in publishers' favor regardless of which path they choose. Publishers who opt out protect their intellectual property from AI feature use but immediately lose any referral traffic those features might generate. Publishers who stay opted in keep feeding content into a system that, by the CMA's own account, is reducing click-through rates to their sites.

Tim Cowen, a lawyer who previously filed a complaint to the CMA over AI Overviews, warned that Google could exploit vague reporting obligations to "slow-roll" compliance — delivering the letter of the requirement while managing implementation timelines to minimize disruption to its own product roadmap. Google has nine months to complete all required changes, with the CMA expecting significant portions to be available well before that deadline. Google must submit compliance reports every six months during the first year, including supporting data.

News Media Europe, representing publishers across the continent, welcomed the requirement but flagged that its effectiveness would depend on enforceability and what it described as "future-proof design" — recognizing that AI systems evolve faster than regulatory frameworks typically do. The CMA said it intends to announce additional action related to Google's search business in the coming weeks without elaborating.

UK's World-First Order in Global Context

The CMA called the June 3 order a "world first" — the first binding conduct requirement imposed on Google under the UK's Digital Markets, Competition and Consumers Act 2024, and the first mandatory opt-out right for AI-powered search enforced by any regulator globally. The law gave the CMA new powers after Google was formally designated as holding strategic market status in October 2025, and the publisher opt-out requirement is the first conduct requirement to emerge from that designation.

The European Union is pursuing a parallel but structurally different track. The European Commission opened two Digital Markets Act specification proceedings against Google in January 2026, and Brussels has been preparing what is described as a record fine against Google's search business for self-preferencing — with an announcement expected before August. A separate EU investigation opened in November 2025 focuses specifically on whether AI Overviews and AI Mode are deprioritizing news publishers in search results.

CMA chief executive Sarah Cardell framed the order as a mechanism for restoring commercial leverage. "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," she said. The order also requires Google to ensure publisher content appearing in AI-generated search results carries clear attribution links to the original source.

Google said the control it is testing in the UK will be rolled out globally, meaning the CMA's intervention may have set the baseline for how AI search products interact with the open web beyond the UK. Whether that translates into meaningful revenue recovery for publishers — or whether the opt-out right functions primarily as a negotiating chip in content licensing talks — is the open question that the next nine months of implementation will answer.

Frequently Asked Questions

How do I opt out of Google AI Overviews as a publisher?

Publishers can use a new toggle inside Google Search Console, available as of June 3, 2026, to prevent their content from appearing in AI Overviews, AI Mode, and AI Overviews in Discover. The setting will not take effect until June 17, 2026, when Google said it will begin acting on the opt-out signal. Activating the toggle will not affect a site's ranking in standard Google Search results.

Does opting out of Google AI Overviews affect search ranking?

No. Google confirmed that the opt-out toggle will not be used as a ranking signal in conventional search results. Publishers who opt out will stop appearing in AI-generated features and will not receive traffic or impressions from those features, but their standard organic rankings remain unaffected.

Will Google's AI Overviews opt-out be global?

Google said it is testing the opt-out controls with a subset of UK website owners first, and plans to roll the feature out to publishers globally after that testing phase. The UK rollout is being conducted under a binding order from the Competition and Markets Authority issued June 3, 2026, the first such requirement issued under the UK's Digital Markets, Competition and Consumers Act 2024.

What does the CMA's Google AI search order not cover?

The opt-out toggle applies only to Google's search products — AI Overviews, AI Mode, and AI Overviews in Discover. It does not apply to the Gemini app, meaning publishers who opt out may still find their content surfacing in Gemini responses. The order also does not require Google to remove content that has already been used to fine-tune its models; the fine-tuning restriction applies to future use only.
