What is Google Preferred Sources, and how does it work?

Google's Preferred Sources feature is now live in every supported language. What it does, how it works, and how to get your site set up for it.

AI SEARCH  |  AUG 29, 2026  | 

Preferred Sources is a Google Search feature that lets individual users choose specific publishers they want to see more of, in Top Stories, Google Discover, and now, with a visible "preferred" badge, inside AI Mode and AI Overviews. It's a direct, user-controlled signal that works alongside Google's existing ranking systems to up-rank sites a specific user has indicated they want to see more from, rather than a ranking factor that applies the same way to everyone.

What changed recently

Preferred Sources launched as an English-only feature. As of April 30, 2026, it's available in all languages where Google Search operates, and Google has published official, translated badge assets in 16 languages, including German, French, Spanish, Dutch (via Portuguese, Swedish, and other regional variants), and Japanese, so publishers outside English-language markets can now build the same kind of audience preference signal.

How it actually works

Preferred Sources selections don't override relevance. A publisher still needs to produce content that's genuinely fresh and aligned with what a user is interested in, since Google Discover in particular is a recommender system that favors freshness heavily. What Preferred Sources adds is an extra weighting signal on top of that: once a user selects a site, Google is more likely to surface that site's content to them specifically, badged as "preferred."

According to Google's own documentation, only domain-level and subdomain-level sites are eligible, a full domain or a subdomain qualifies, but a subdirectory like `example.com/blog` does not.

How to help users select your site

Google outlines three implementation options, all aimed at the same outcome: making it easy for a visitor to add a site as a preferred source without leaving the page.

01
Standard JavaScript button (Google's recommended option). Two lines of code embed an automatically localized, Google-styled button that lets a reader add the site as a preferred source and return exactly where they left off.
02
Advanced JavaScript with custom design. For sites that want their own visual design instead of Google's default button, the same underlying flow can be triggered from a custom UI element.
03
Deeplink implementation. For sites that can't add JavaScript, a plain link or clickable image pointing to Google's source preferences tool works as a lower-effort alternative, and can also be used in email newsletters or social posts, not just on-site.

What this means practically

Preferred Sources isn't something a site can manipulate directly, it's entirely a user choice. The realistic opportunity for publishers and SEOs is using it as one more way to build an audience: prompting genuinely engaged readers to select the site once, so future content gets a visibility boost specifically with that reader, across Top Stories, Discover, and now AI Mode and AI Overviews as well.

FREQUENTLY ASKED QUESTIONS

The questions people actually ask.

What is Google's Preferred Sources feature?
A feature that lets individual Google users choose specific publishers they want to see more often in Top Stories, Google Discover, and, more recently, with a "preferred" badge inside AI Mode and AI Overviews. It's a user-controlled signal that works alongside Google's standard ranking systems.
Is Preferred Sources available outside English-language sites?
Yes, as of April 30, 2026. It launched as an English-only feature and is now available in every language where Google Search operates, with official translated badge assets published in 16 languages.
Can a subdirectory or blog section be a preferred source?
No. Only domain-level and subdomain-level sites are eligible. A subdirectory, such as a blog living at example.com/blog, doesn't qualify on its own; the eligible unit is the domain or subdomain itself.
Does adding a Preferred Sources button directly improve rankings?
Not in the traditional sense. It doesn't override relevance or general ranking, a site still needs to publish genuinely fresh, relevant content. What it does is create an added preference signal specific to each user who selects the site, which can increase visibility with that individual over time.
