Does Google Preferred Sources affect AI Mode: Google documents a badge, and its click figure is older than the feature there
In AI Mode and AI Overviews, a website that someone has picked "can be highlighted with a 'preferred' badge" for that person, according to Google's documentation for site owners. For Top Stories, the same documentation promises something different: there, the chosen site "is more likely to appear". The one click figure we found Google publishing for the feature is a doubling of clicks to publications people picked. The doubling first appeared on 10 December 2025 and again on 30 April 2026, while the feature customised Top Stories. Google announced Preferred Sources for AI Overviews and AI Mode on 27 May 2026, in the post that repeated the figure.
Our own business is measuring which sources AI answers cite, so a change to how a link looks inside those answers sits close to what we sell, and you should read this page knowing that. We have not tested the feature: we have counted no people who picked a publication and no clicks that followed, we hold no data of our own on it, and nothing below is a measurement of ours.
What follows is a reading of Google's own record — five blog posts on the feature from August 2025 to August 2026, its documentation and its help page — set beside the pages we could open among those ranking for this question in Google Search results in the United States on 29 September 2026, and other coverage we found by searching. We read them; we did not sample or count them. Several of them had already made parts of this argument, and each is credited where it made it.
What are Google's preferred sources?
A person picks websites in Google's Search personalization settings to see more of them in Top Stories and to have them labelled in AI answers, and Google calls those websites preferred sources. In the help page's words, chosen sources turn up "more often in Top stories when they publish fresh content related to your search". The feature launched on 12 August 2025 in the U.S. and India inside Top Stories. It reached English-language users worldwide from December 2025, every supported language on 30 April 2026 ("Preferred Sources is now available in all languages."), AI Overviews and AI Mode on 27 May 2026, and gained an embeddable button on 20 August 2026 that adds a website to someone's list in one click.
Google says "Any website that publishes fresh content is eligible", and its documentation limits the choice to whole domains and subdomains: "Only domain-level and subdomain-level sites are eligible to appear in the source preferences tool." A blog kept in a subfolder, for example, cannot be picked on its own. A signed-in person keeps the same list "in every browser you sign into".
What changes inside AI Mode and AI Overviews?
Google's documentation, last updated on 18 September 2026, promises a "preferred" badge for a chosen publication in AI answers and says nothing about a better position in them. Its words are: "In AI Mode and AI Overviews, your content can be highlighted with a 'preferred' badge for users who have selected your site as a preferred source." For Top Stories, the same paragraph goes further and says the content "is more likely to appear" as well as carrying the badge — two different promises for two surfaces.

Duncan Osborn, a product manager on Google Search, described the change the same way when it launched on 27 May 2026: the company was "bringing your Preferred Sources directly into our AI experiences", and people would "easily spot links in AI responses" from sites they had already chosen, which would be "clearly labeled to stand out". The help page speaks of tailoring Search "to highlight content" in those two features. For some questions about a developing topic, the same post added "a prominent carousel, which will also highlight your Preferred Sources", with "a similar carousel with helpful perspectives from online discussions, forums, and social media" to follow. It also widened a separate "Highly Cited" label, which marks articles "that many other stories have cited"; that label is not the preferred badge.
Availability differs by surface. Top Stories carries the feature "in all languages where Google Search is available", while the two answer features carry it "in all languages and locales where those features are available". The documentation adds one condition for those two: "To make your site eligible for display as a preferred source in these features, you must make sure your site is included in Search generative AI features in Search Console."
SEO Kreativ, which ranks for this question, and PPC Land read the documentation this way before we did: in those answers, as SEO Kreativ puts it, "their links carry a label". What the documentation leaves open is whether picking a site makes it more likely to be included in an answer at all. "Highlight" could cover more than a label, and the carousel may favour chosen outlets in ways the text does not spell out; the Google pages we read neither say so nor rule it out, and we have not tested it.
Where does "twice as likely to click" come from?
Google's click figure first appeared on 10 December 2025, in a Google post whose paragraph on the feature was about letting people "customize Top Stories to see more from your favorite outlets and sites". In that paragraph, Robby Stein and Jaffer Zaidi wrote that "When someone picks a preferred source, they click to that site twice as much on average".
The 30 April 2026 post repeated it in new words, "readers are twice as likely to click through to a site after marking it as a Preferred Source", while describing a feature for choosing the sites "you want to appear more often in Top Stories". The 27 May 2026 post then brought the feature to AI Overviews and AI Mode "starting today" and said, in the same section: "We've found that people are twice as likely to click through to a Preferred Source, and people have already selected more than 345,000 unique sources."
As far as the Google pages we read show, the company's only published click figure for Preferred Sources was already in print on 10 December 2025 and 30 April 2026, before the 27 May 2026 post announced the feature for AI answers and repeated it. The click figure is therefore older than the feature in AI answers. Search Engine Roundtable reported a test of the preferred label in AI Mode citations on 20 May 2026, from one person's screenshot it could not replicate; both earlier printings came before that. The 27 May 2026 post does not say whether the figure was measured again on those answers, on Top Stories, or on both.
None of the Google pages we read gives a click figure for AI Mode as such, and that does not make the older figure wrong for it. PPC Land noted on 21 August 2026 that the claim "has held steady since December"; what that steadiness means for the newer surfaces is the part none of the pages we read spells out.
What is the click figure compared against?
Google has given no baseline, population, surface or period for its click figure in any of the three posts that state it. The comparison is left for whoever reads it to supply. The wordings point different ways. "Twice as much on average" could compare one person's clicks on a site before and after picking it, or picked outlets with the rest. "After marking it" reads most like a before-and-after for the same person. "Twice as likely to click through to a Preferred Source" reads most like picked sites against the other links on the same page.

Coverage of the May post filled that gap in three ways too. Search Engine Journal reported clicks "at twice the rate of other links", PPC Land wrote "compared to non-labeled links", and Pixelmojo concluded: "It tells you the badge changes behavior." Search Engine Journal also asked the question that matters, on the day of the launch: "The company didn't share how that metric was measured or whether the comparison controls for user intent."
We think that question decides what the figure can carry. Someone who has taken the step of picking a publication already wants to read it, so that person clicking it more often than a site they never picked is close to what picking means. A comparison of that kind cannot separate what the badge adds from the preference the person brought with them. It does not show that the badge adds nothing, either: the company may have measured this carefully and simply not published the method.
For what published studies say about clicks when an AI Overview appears at all, we read those separately. They measure a different thing, and none of their numbers is set against the doubling here.
What do 345,000 and 600,000 count?
Google's source counts measure the websites people picked, not the people who picked them. The company's words are "unique sources", and in April "unique sites". The count stood at nearly 90,000 unique sources on 10 December 2025, over 200,000 unique sites on 30 April 2026 and more than 345,000 on 27 May 2026. By 20 August 2026, people had picked more than 600,000 unique sources. Mrinalini Loew, general manager of the Search ecosystem, gave that figure.
The only per-person figure Google has published on Preferred Sources comes from its 2025 Labs test, where early users valued picking a range of outlets, "with over half of users choosing four or more" (12 August 2025). One person can account for several of the entries counted. On our reading of "unique", which none of the posts defines, a site picked by one person counts once, the same as a site picked by thousands. PPC Land put it plainly: the number counts "not selections made and not users making them".
A count of 600,000 sites cannot tell any one publisher how many of its own readers picked it, and the company publishes no figure that could. SEO Kreativ reads the rise from 345,000 to 600,000 as a sign that "The feature is genuinely used, not just tested", and that holds as far as it goes: people are picking them. The count does not say how many people.
What can a site owner see about its own readers?
Google gives a publisher no count of the readers who picked it. "Google does not yet give you a report telling you how many readers added you as a preferred source," origami.sa wrote on 22 August 2026, and PPC Land reported that Search Console has no dimension for it either.
A publisher that embeds the button, PPC Land adds, "can count clicks on the button through its own analytics, and can observe nothing downstream of it". The documentation frames the button and a plain link as ways to "build your audience", and the link "takes users directly to your site" in the tool. Of the click figure itself, SEO Kreativ says: "A concrete traffic figure can't be derived from that, because the effect depends on the size of your loyal reader base."
The gap between what the company counts and what a publisher can check is not unique to this feature; it runs through Google's AI contribution pilot as well.
So does Preferred Sources affect AI Mode?
Preferred Sources affects AI Mode, on Google's documentation, by marking a chosen site's link for the person who chose it; a mark is what the documentation promises there. The company's posts use wider words, that the feature "makes it easy to see more from your favorite websites" (27 May 2026) and that readers "more easily find their favorite publications in Top Stories, AI Overviews, and AI Mode" (20 August 2026), without saying whether that means more than the mark. Whether a pick changes which sites an AI Mode answer includes, the company has not said, and we have not measured it.
Whether asking your readers to pick your publication is worth the effort is your call, and the feature works one person at a time. SEO Kreativ calls it "not a classic ranking signal, but a user-driven visibility mechanism", and Pixelmojo's summary is the fair one too: "It is a personalized signal, not a universal ranking factor."
Three things would change this reading: a count of the people who have picked publications, a method for the click figure, or documentation of how picked sites enter those answers. We will keep reading Google's record of the feature and publish what changes.
