Google has moved its Preferred Sources feature into AI Overviews and AI Mode, meaning the loyalty a publisher builds with its audience now has a direct effect on how prominently that publisher appears inside AI-generated search answers.
When a user has added a domain via google.com/preferences/source, links from that domain surfacing inside an AI Overview or AI Mode response will carry a visible “Preferred” badge. Duncan Osborn, Product Manager for Google Search, stated that users will “be able to easily spot links in AI responses from the sources you’ve already selected.”
More than 345,000 unique sources have now been selected across the platform, up from roughly 90,000 when Google expanded the feature globally. That is roughly a fourfold increase. The growth coincides with publishers beginning to promote the feature to their own readers, which suggests the distribution of the signal is partly self-reinforcing: sites that already have strong audience relationships capture it fastest.
Google reports that users click through to Preferred Sources at twice the rate of other links. The company has not disclosed the methodology behind that figure or whether the comparison controls for user intent, so the number should be treated as a directional signal, not a verified lift estimate.
John Mueller addressed the scope question directly: Preferred Sources works alongside existing ranking systems rather than overriding them. A low-quality page from a preferred domain does not jump to the top of an AI answer by virtue of the label alone. The badge affects visibility and click behavior once a source appears. It does not substitute for the underlying quality signals that determine whether a source appears at all.
Sundar Pichai, speaking in a Decoder interview, described a related direction where subscribed sites receive preferred treatment, calling it “a new change which we didn’t have before.” That framing suggests Google sees source preference as an evolving layer on top of its ranking architecture, not a one-time feature add.
The same announcement included a “Highly Cited” label expansion. The badge, which originally launched in 2022 for mobile Top Stories, now appears on more web article links in standard results. Google is also adding a secondary label that flags when an article explicitly references a Highly Cited source, making citation chains visible to users scanning results. This expansion applies to standard search results and is separate from the AI Overviews and AI Mode changes.
The practitioner implication is specific. Adding a source to the Preferred list is a single-step action that most readers will not take unless prompted. Publishers who have an owned-audience channel, a newsletter, a notification list, or an active social following should include an explicit call to action pointing readers to google.com/preferences/source. A one-sentence prompt in a newsletter footer, or a sticky banner for logged-in Google users on article pages, is enough to drive selection. The 345,000 figure grew fourfold largely because publishers started asking. Sites that have not yet asked are leaving a compounding signal on the table.
The strategic shift here is that AI search visibility is no longer determined solely by what Google thinks of your content in the abstract. A portion of it now depends on whether your readers have taken an action on your behalf. Teams managing search strategy for content-driven brands should treat Preferred Source acquisition as a metric alongside organic ranking, because the two now feed the same outcome inside AI Mode.
