Google Preferred Sources lets searchers choose the websites they want to see more often. Chosen sites surface more in Top Stories and carry a “Preferred” label in AI Overviews and AI Mode. Google’s October 15 update pushed those labels into more carousels and said usage has grown more than 7x this year. Any domain publishing fresh content can qualify.

This guide covers what the update changed, the eligibility rules that trip up most B2B sites, the two-line button setup, and how to measure whether the effort pays off.

Google Preferred Sources, explained

Preferred Sources began as a Top Stories setting. Google launched it in the U.S. and India on August 12, 2025: a searcher taps the icon beside Top Stories, picks sites, and then sees more of their fresh articles in that carousel or in a “From your sources” section. More than half of early Labs testers picked four or more sources (Google).

The feature reached every supported language on April 30, 2026 (Google). On May 27, Google brought it into AI Overviews and AI Mode, where links from a searcher’s chosen sites now carry a “Preferred” label. The same announcement said any website that publishes fresh content is eligible, which opens the feature well beyond newsrooms (Google).

The October 15 update to AI Mode and AI Overviews links

Google’s October 15 announcement made five changes to how AI responses send people to the web (Google):

  • More inline links, placed higher. Google says it has made “continued and substantial increases” to links embedded in AI response text and will show them higher in responses more often.
  • An official-links section, in testing. When only one or two official pages can complete a task, a dedicated section at the top of the response will surface them with context on why each is useful.
  • Wider article carousels. Carousels for timely articles are rolling out to more locations and languages, and they highlight the searcher’s Preferred Sources.
  • Related-article thumbnails. Links at the end of some AI responses get image thumbnails and a more clickable design.
  • Clickable creator names, in testing. Creator and publisher names on AI Mode video results now link to their Search profiles.

For site owners, the carousel change carries the most weight. It is the one surface where Google says it highlights a searcher’s Preferred Sources inside AI search on a wider range of queries. Search Engine Land’s Barry Schwartz doubted the extra links will win many clicks, since Google still withholds AI click data from Search Console’s AI reports (Search Engine Land). Our AI Mode SEO guide covers the ranking side of the same surfaces.

Google Preferred Sources by the numbers

Google has shared three figures, all its own. Readers are twice as likely to click through to a site after marking it as a Preferred Source (Google). Selections grew from more than 200,000 unique sites on April 30 to more than 345,000 by May 27 (Google). And on October 15, Google said the number of people using the feature had grown more than 7x since January (Google).

None of these figures comes with a baseline or a per-site breakdown. Read the 2x number as a measure of intent: people who opt in to a source were already inclined to read it. The longer-term stakes may rise. 9to5Google reported in May that Google is working on using Preferred Sources as a ranking signal across its AI features (9to5Google). Google has announced no date for that.

Eligibility rules for Google Preferred Sources

Google’s documentation sets two conditions (Google Search Central). Only domains and subdomains appear in the source preferences tool, so www.example.com and code.example.com qualify while www.example.com/blog does not. For the AI features, the site must also be included in Search generative AI features through the Search Console control.

The first rule catches B2B companies whose content lives in a /blog/ or /insights/ folder. Selecting the root domain is the only route, so every call to action should name the domain itself. The second rule bites only if someone switched the control to exclude the site. Inclusion is the default for every property, and a change takes a few days to apply (Search Console Help). Our Search Console AI performance report guide shows where that setting sits.

Setting up a Preferred Sources button in six steps

Google calls these methods optional; a site can appear as a preferred source without any of them (Google Search Central). Their job is to make the choice easy for readers who already value your content.

  1. Check that your domain is listed. Search for your domain in Google's source preferences tool at google.com/preferences/source. If it appears, you can promote it.
  2. Confirm the generative AI control. In Search Console, open Settings, then Search generative AI, and confirm the property includes its links and content.
  3. Add the button to your template. Load publisher.js from news.google.com in the page head, then place a div with the google-add-preferred-source-btn attribute where the button should render. Add data-theme="dark" on dark layouts.
  4. Use the deeplink where scripts cannot run. Link to https://www.google.com/preferences/source?q=yourdomain.com from newsletters, email signatures, and social posts.
  5. Tell readers what they get. One line does it: choosing your site means more of your articles in their Top Stories and a Preferred label on your links in AI Overviews and AI Mode.
  6. Track clicks on the button and deeplink. Send both as a GA4 event so you can see which pages and emails drive selections.

The script, deeplink format, and official badge assets all come from Google’s publisher documentation. Adding a script to a site template and wiring the click into GA4 is routine work for our digital marketing and technology team.

The Preferred Sources payoff for SMB and B2B sites

Preferred Sources rewards the audience you already have. It behaves like a subscribe button inside Google: a reader opts in once, and your articles show up more prominently whenever you have published something fresh and relevant to their search (Google).

That favors companies publishing on a steady schedule about subjects people search while they are changing: platform updates, regulation, pricing, industry data. A firm that posts twice a year will see little from it. A team shipping a weekly insight has good reason to put the button in every newsletter.

First-touch discovery is a separate problem. A searcher who has never heard of you has no reason to pick you, so earning citations from new audiences stays the work of answer engine optimization.

Measuring the October AI search link changes

Expect thin data. Search Console’s generative AI performance report counts impressions only, and AI clicks sit blended into the main Performance report, so more inline links will show up as small shifts on individual pages. Schwartz made the same point in his coverage of the update (Search Engine Land).

Assistant referrals are getting noisier as well. Search Engine Land reported on October 15 that ChatGPT links appear to have dropped the utm_source=chatgpt.com tag. Adobe’s Cedric Huesler found ChatGPT referrals down about 31,000 visits a day across roughly 500 pages, while direct traffic rose about 26,000 a day on the same pages. OpenAI has not confirmed the change (Search Engine Land). Watch direct traffic on pages that used to draw assistant visits, and recheck your GA4 AI traffic setup.

For Preferred Sources itself, the cleanest signals are button and deeplink clicks, the returning-visitor share of Google organic traffic, and AI impressions on your timely pages. Annotate October 15 in your reports so the before-and-after reads cleanly.

Next steps for this quarter

Check the tool, confirm the control, add the button to your newsletter and article template, and give it a full quarter before judging. Content worth choosing comes first; the button only shortens the path for readers who already like it.
