Google has introduced three recent changes: a Search Console opt-out toggle for AI features, Preferred Sources integration inside AI Overviews and AI Mode, and a "Highly Cited" badge for influential content. Together, they shift how publishers should think about visibility in an AI-mediated search environment.
The Opt-Out Toggle
Google is rolling out a new Search Console toggle that lets website owners control whether their content appears in AI Overviews and AI Mode. Sites that opt out will no longer receive traffic or impressions from those features. Critically, Google has stated this toggle will not function as a ranking signal for standard search results outside of AI features. The toggle is being tested first with a subset of UK website owners before a global rollout.
What this means for brands: A brand's AI visibility isn't only a function of its own content decisions. It's also contingent on whether the publishers citing that brand choose to stay in. If The Guardian, The Financial Times, or any other high-authority site that carries substantial earned mentions of your product or company opts out, those citations disappear from AI responses entirely. Knowing which third-party domains influence AI's perception of your brand is foundational to GEO, but now tracking whether those domains are signaling intent to opt out is becoming increasingly important.
Preferred Sources Inside AI Responses
The Preferred Sources feature, which previously let users designate favorite websites so those sites appeared more prominently in Top Stories, has now been extended into AI Overviews and AI Mode. When a user has selected a site as a Preferred Source, links to that site will be visibly labeled inside AI-generated responses.
What this means for brands: Google reports that users are twice as likely to click through to a Preferred Source, and more than 345,000 unique sources have already been selected by users globally. Publishers who cultivate genuine reader relationships (the kind where readers seek them out and register them in a preference setting) will see their content labeled and surfaced preferentially inside AI responses. Content farms with no brand loyalty get no such benefit. Google has published documentation for site owners on how to encourage readers to add them as a Preferred Source.
Highly Cited Badge
Google is expanding the "Highly Cited" badge to more web article links in search results, identifying articles that have been cited extensively by other stories and marking original reporting as a distinct content category. Unlike E-E-A-T and other quality signals that are assessed algorithmically and invisible to users, the Highly Cited badge makes citability a user-facing attribute. Content that becomes a primary reference for other publications now carries a visible mark of authority inside search results. It favors original reporting, primary research, and first-person expert analysis. Derivative or aggregated content, by definition, cannot accumulate the cross-publication citations needed to earn it.
What this means for brands: The Highly Cited badge is effectively a public leaderboard for original thinking. If your brand publishes research, data, or expert analysis that other outlets pick up and reference, that content can now earn a visible authority marker inside search results — one that users see and that AI systems use to weight sourcing decisions. The inverse is equally true: content that summarizes, aggregates, or rehashes existing coverage will rarely earn it. For brands that have been treating content as a volume play, this is a concrete signal that one well-researched, citable piece of original work outperforms 10 derivative posts in an AI-mediated search environment.
What This Means for GEO Strategy in 2026
Google is differentiating between content that AI should draw from and content that merely exists on the web. For content teams, the focus should be on whether your content is the kind that other publications cite, whether your readers know your brand well enough to register you as a Preferred Source, and whether your pages are structured to be accurate and useful when synthesized by a large language model rather than read linearly. And for marketing teams measuring and optimizing in AI Search, ensuring that your mentions on earned sources are not opting out of Google's AI Mode and AI Overviews.
