THE DEFINITION
What is Google Preferred Sources?
Preferred Sources lets any signed-in Google user star the sites they trust. Star a site, and its fresh content shows up more in your Top Stories, and its citations inside AI Overviews and AI Mode carry a “Preferred” badge. Since 20 August 2026, publishers can put a one-click version of that star on their own pages with two lines of code.
It is the first lever in AI search that belongs to your audience rather than to you or to Google: readers voting your site into their own results. Google reports users are roughly twice as likely to click through to a source they preferred.

The official button, verbatim from Google’s documentation:
<script async src="https://news.google.com/swg/js/v1/publisher.js"></script>
<div google-add-preferred-source-btn></div>Or the no-JavaScript deeplink, which also works in newsletters and social posts:
https://www.google.com/preferences/source?q=yourdomain.com→ Place it at a moment of goodwill: the end of an article, next to your share buttons, after a reader finishes something they came for.
→ Eligible: domains and subdomains. Not eligible: subdirectories.
This is not a ranking hack, and pages that sell it as one are overselling. The star is per-user: it changes results only for readers who chose you, and Google is explicit that a preferred source still has to publish fresh, relevant content to appear at all. Think of it as a tiebreaker your loyal readers hand you, not a lever you pull.
That shape has a consequence worth sitting with: it rewards sites people actually return to. A site with no repeat readers gains nothing from the button. Which makes it a loyalty metric wearing a search feature’s clothes, and a very good reason to build things people come back for.
Answer engine optimization has so far been publisher-side: publish verified facts, serve llms.txt, mark up your pages, sign a record. Preferred Sources adds the missing side: the reader’s. Provenance says this is true; preference says I want this source. Engines get both signals, and sites holding both are hard to displace.
The Grounded audit’s Fix it page now hands you the exact paste-ready button snippet alongside your record, schema, and llms.txt patches, so both halves ship together.
What is Google Preferred Sources?
Preferred Sources is a Google Search feature that lets a signed-in user mark sites they trust. Once a user stars your site, your recent content is more likely to appear in that user's Top Stories, and when your pages are cited in AI Overviews or AI Mode, they carry a "Preferred" badge for that user. It is personal to each user who stars you; it does not change rankings for anyone else.
How do readers add my site as a preferred source?
Three ways. They can search your site name on Google and use the star control next to it, you can send them a deeplink of the form google.com/preferences/source?q=yourdomain.com, or, since 20 August 2026, you can embed Google's official one-click button on your own pages with two lines of code.
What is the embed code for the Preferred Sources button?
Two lines: a script tag loading https://news.google.com/swg/js/v1/publisher.js, and an empty div carrying the google-add-preferred-source-btn attribute. Google renders a translated, one-click button in place and returns the reader to your page after they confirm.
Does Preferred Sources improve my ranking?
Not globally, and it is worth being precise. It is a per-user tiebreaker: for users who starred you, your fresh, relevant content is more likely to be shown and is badged when cited. Google states preferred sources still have to publish content worth showing; the star does not override quality or relevance for anyone, and it changes nothing for users who never starred you.
Which sites are eligible?
Domains and subdomains (example.com or blog.example.com), not subdirectories (example.com/blog). It is available globally for Top Stories in every language where Google Search operates, and surfaces in AI Overviews and AI Mode wherever those features are live.
Why does Preferred Sources matter for AEO?
It is the first user-controlled lever over which sources AI search surfaces. Everything else in answer engine optimization is you talking to machines: records, schema, llms.txt. This one is your audience voting you into their own AI results. Google says users are roughly twice as likely to click a preferred source, and the badge appears exactly where AI answers otherwise absorb the click.
How is this different from a v=AEO1 record?
They answer different trust questions and stack well. A v=AEO1 record proves what is true about you: verified facts, signed, anchored in DNS, readable by any engine. Preferred Sources proves who wants you: readers who explicitly chose your site. Provenance plus loyalty is a stronger position than either alone.
