Google gives publishers an embeddable button that feeds AI Overviews and AI Mode
Google announced on 20 August 2026 that publishers can now embed a button on their own pages which adds their site as a reader’s Preferred Source on Google Search and returns the reader straight back to where they were, instead of routing them through Google’s settings screen. Implementation code is published in Google Search Central documentation. Writing on the Google blog, Mrinalini Loew, general manager for the Google Search ecosystem, said readers find their chosen favourites “in Top Stories, AI Overviews, and AI Mode”, and that more than 600,000 unique sources have been selected so far.
Why this matters
Preferred Sources is a per-reader signal rather than a ranking factor, which changes what it is useful for. It does not lift a site for people who have not opted in. What it does is convert an audience a publisher already has – a newsletter list, a Facebook following, regular readers – into visibility on the surfaces where AI answers get assembled. For a small independent publisher competing against large outlets for citation in AI Overviews and AI Mode, that is a route to prominence that does not depend on outranking anyone. The practical step is two lines of HTML on pages your existing readers actually land on, then an ask in the places where those readers already pay attention.
Context
This extends a feature Google launched for readers earlier in 2026, when Preferred Sources had to be set from within Google’s own settings; the number of sources selected has risen from roughly 345,000 in late May to over 600,000. Eligibility is at domain or subdomain level, so a site published in a subdirectory of someone else’s domain does not qualify. It arrives in the same fortnight as Cloudflare’s Bot Preference Sync and the launch of ChatGPT advertising across 31 European markets, in a period where the terms on which publishers appear inside AI answers are being reset from several directions at once.
What to watch
Google published no list of the markets where the button is available, and did not state whether it works outside the United States. European publishers should confirm availability before building it into a plan. Google also released no data on how much visibility a Preferred Source designation actually buys.
