Google’s Preferred Sources feature lets users choose publications they want to see more prominently in supported search experiences. Google says selected sources can receive highlighting in Top Stories and, where available, AI Mode and AI Overviews.
Quick Answer
Preferred Sources is a user-choice feature, not a switch publishers can use to promote themselves universally. Publishers should focus on being a publication readers intentionally want to follow, make sure the site is eligible for relevant Search features, and explain the option honestly to their audience.

What the Feature Does
When a user selects a site as a preferred source, Google says that source is more likely to appear in Top Stories for that user and can receive a preferred badge. Preferred sources can also be highlighted in AI Mode and AI Overviews where those features are available.
What Publishers Can Control
A publisher can create useful, recognizable coverage, maintain a clear site identity and let loyal readers know the feature exists. The user still decides whether to select the source.
Do Not Confuse Preference With General Ranking
The feature relates to an individual user choosing a source. It should not be described as a universal ranking boost for everyone or as a replacement for normal crawl, indexing and quality requirements.

Publisher Readiness
- Maintain a clear publication identity.
- Publish distinctive useful coverage.
- Keep site and author information trustworthy.
- Confirm eligibility for relevant Search features.
- Explain Preferred Sources without coercive claims.
- Measure actual search performance rather than assuming a universal boost.
Current Availability and Eligibility
Google’s current documentation says Preferred Sources is available globally for Top Stories in all languages where Google Search is available. Preferred sources can also appear in AI Mode and AI Overviews wherever those features are available. For a site to be eligible for preferred-source display in those generative AI experiences, Google says the site must be included in Search generative AI features in Search Console.
Google also limits source-preference eligibility to domain-level and subdomain-level sites. A full domain such as example.com or a subdomain such as news.example.com can be eligible, while a subdirectory such as example.com/blog is not treated as a separate source in the preference tool.
How Publishers Can Surface the Option
Google documents an interactive JavaScript button as the recommended implementation and also supports a deeplink to the source-preferences tool. These methods help an existing reader choose the publication; they are not required merely to be eligible as a preferred source.
The editorial implication is straightforward: earn enough trust and usefulness that a reader wants to select the site, then make that choice easy to discover. Do not market the feature as a guaranteed ranking boost. The preference belongs to the individual user and affects supported experiences for that user.
What Not to Overclaim
Do not claim that becoming a preferred source guarantees top rankings, AI citations or traffic increases. The effect depends on individual user preferences and feature availability.
