What is a preferred source?

A preferred source is a site that a signed-in Google user has added to their own source preferences. Google then favours that site for that user: its articles surface more often in the Top Stories module, and links to it carry a visible “preferred” label inside AI Overviews and AI Mode.

The selection lives in the reader’s account, at google.com/preferences/source. Nobody else’s results change.

What makes preferred sources different from every other search feature?

Preferred sources is decided by one person clicking a button, not by Google’s systems reading signals like links, structured data, reviews, freshness or entity consistency the way everything else a site appears in is.

That has three consequences an operator should hold onto:

  • There is no ranking to compete for. No threshold of selections unlocks a general boost. Google has documented no aggregate effect from preferred-source counts.
  • There is nothing to buy. No paid placement, no application, no agency that can arrange it.
  • The only lever is asking. Google ships an embeddable button and a deeplink so a publisher can ask on its own pages, and states plainly that using them is not required in order to appear as a preferred source.

Who is eligible to be a preferred source?

Only domain and subdomain level sites appear in the source preferences tool. example.com and news.example.com can be selected; example.com/blog cannot. A property whose content lives in a subdirectory of a larger site has nothing to select.

Check a domain before planning anything around this, because the answer is often no.

Why would a hospitality operator care about preferred sources?

A hotel has the audience this feature rewards and most publishers do not: past guests, newsletter subscribers, loyalty members, local followers, and the planners who book events. Those are people who already chose the property once. Preferred sources is the search feature that converts that existing relationship into visibility inside an AI answer, and it is the only one that does.

It does nothing for a traveller who has never heard of the property. That limit is the point, not a flaw.

The full picture, with the timeline and the implementation, is in the publisher’s guide to Google Preferred Sources.
