Google's New Preferred Sources Button Lets Publishers Win Back Clicks from AI Search

Google has released an embeddable button that publishers can place on their own websites, letting readers mark a site as a preferred source across Google Search, Discover, and Google News. The button code appeared in Google's Search Central documentation on August 20, 2026 (Google Search blog; TechCrunch).

When a reader presses the button on a publisher's site, that site gets added to a personal list of preferred sources. Google says preferred sources receive more traffic, citing earlier studies in which people were twice as likely to click through to a preferred source when one was available (TechCrunch).

Readers can also add a favorite publisher without the button by visiting Google's source preferences page at google.com/preferences and searching for a publisher by name or website (TechCrunch).

The on-site button builds on a feature Google has been rolling out in stages. In September 2025, Google added the ability to choose preferred news sources within Top Stories in Discover, Google's personalized content feed on mobile (Google Search blog). Readers can select preferred sources in Top Stories by searching for a topic in the news and clicking the icon to the right of the Top Stories section (Google Search blog). In May 2026, Google extended Preferred Sources into its AI experiences, including AI Mode and AI Overviews, the generated summaries that appear at the top of some search results. This lets readers label preferred sources in their settings so those sites are highlighted within AI-generated responses (Google Search blog; Google Search Central). As of that May launch, people across the web had selected over 345,000 unique sources through the feature (TechCrunch; Google Search blog).

Google has also published a Guide to Preferred Sources in its Search Central documentation, covering eligibility criteria and how publishers can guide users to select their site as a preferred source (Google Search Central).

Alongside the button, Google said readers will soon be able to customize their Discover feed in the Google app using natural language commands, accessed through the three-dot menu, to indicate topics they want to see more or less of. Android users will also be able to customize their audio daily briefings in the Google News app (TechCrunch).

Google has been actively iterating on the systems that surface content to readers. In February 2026, the company released a Discover core update, described as a broad update to the systems that surface articles in Discover (Google Search Central). It has also published a guide to optimizing for generative AI features on Search and Discover, including how to measure content performance via the Generative AI performance report in Search Console (Google Search Central).

The broader context here is the tension between Google's AI-driven search surfaces and the publishers who supply the underlying content. AI Overviews and AI Mode synthesize answers from publisher content, reducing the need for a reader to click through to the original source. Preferred Sources gives publishers a mechanism to reassert a direct relationship with readers, and gives readers a lever to push specific sites into the AI-generated responses themselves. Google's own data, showing a 2x click-through uplift for preferred sources, provides a concrete incentive for publishers to prompt their audiences to use the feature.

There are open questions worth flagging. The 345,000-source figure predates the on-site button, so adoption metrics post-launch are not yet available. The feature is opt-in for readers and requires publisher initiative to promote it, which means larger publishers with engaged, returning audiences are better positioned to benefit than smaller outlets or those dependent on search-discovered traffic. And while Preferred Sources can elevate a chosen site within AI-generated responses, it does not change how Google's systems select which sources to synthesize from in the first place; a reader who prefers a given outlet may see it highlighted, but the underlying generation pipeline remains opaque.

What the feature does enable is straightforward: a reader who has invested the effort to designate preferred sources gets a more persistent signal across Search, Discover, News, and now AI Mode, and publishers get a measurable, if modest, traffic uplift for their part. Whether that is enough to offset the broader shift in referral patterns as AI-generated answers absorb more of the query surface is a separate question that the button alone does not answer.
