TL;DR: Google’s Preferred Sources feature, which lets people mark outlets they want to see more of, has been adopted by 345,000 publishers, and citations pulled from that list inside AI Mode and AI Overviews have risen roughly sevenfold since Google extended the feature there.

Google quietly built a tool over the past year that lets individual users pick which publishers they would rather see more often in their results. It is called Preferred Sources, it sits in a corner of Search settings most people never open, and new numbers out this week show it has actually caught on. Roughly 345,000 publishers have now configured their sites to be selectable through the feature.

The more interesting figure is what happens once someone sets a preference. Google originally confined Preferred Sources to the plain blue-link results people have used for decades. Over the summer it started threading that same signal into AI Overviews and AI Mode, the generative answer boxes that increasingly sit above or instead of traditional results. Since that expansion, citations in those AI answers that trace back to a user’s preferred outlets have risen close to sevenfold.

For publishers, that is a meaningfully different story than most of what has come out of Google’s AI push this year. The dominant narrative in SEO circles has been one of shrinking referral traffic, as AI Overviews answer a question directly and give the user little reason to click through to the source. Preferred Sources flips part of that dynamic, at least for the slice of readers who bother to set it, by giving a specific publisher a better shot at being the one AI Mode quotes or links.

The catch is scale. Setting a preferred source requires a reader to actively click a small star or toggle next to a result, and most people searching Google have never noticed the option exists, let alone used it. A 7x jump in citation share among a self-selecting group of engaged users is a real signal, but it does not mean AI Overviews have become friendlier to publishers across the board. The broader decline in click-through rates that prompted all the hand-wringing in the first place has not reversed.

What it does suggest is a new lever publishers can actually influence. Rather than trying to guess how a language model weighs authority signals, a site can work directly to earn the kind of reader loyalty that leads someone to mark it as preferred, and that preference now carries real weight even inside an AI-generated answer. SEO teams covering this closely are already treating it as a new, smaller but more controllable ranking factor.

Google has not said whether it plans to expose Preferred Sources more prominently in the interface, which would presumably drive adoption well past the current 345,000-publisher mark. For now the feature remains opt-in and somewhat buried, which keeps its overall impact on traffic modest even as its effect on the users who do use it grows sharply.

Bottom Line: Preferred Sources is a genuinely useful lever for publishers who can get readers to opt in, but it is still a niche setting, not a fix for the broader traffic losses AI answers have caused across the web.
