Google rolls out Preferred Sources button as AI Overviews keep pressuring publisher traffic

Google has introduced a new "Preferred Sources" button that publishers can embed directly on their websites, letting readers add a media outlet to the list of sources they want to see more often across Google Search, Discover and Google News. The company said reader adoption of Preferred Sources rose from 345,000 to 600,000 in three months, and early research suggests users are twice as likely to click when a preferred outlet appears in results. The rollout comes as publishers face mounting traffic losses tied to AI-generated search products. According to research cited in the report, Ahrefs said in February 2026 that AI Overviews cut click-through rates for top-ranking pages by 58%, compared with a 34.5% decline in a similar study published in April 2025. Pew Research Center also found that users clicked traditional search results 8% of the time when AI summaries appeared, versus 15% when they did not. Google is also expanding user controls in Discover and Google News, but the article argues the deeper issue remains unchanged: Google still controls recommendation logic, placement and inclusion in AI summaries, while publishers are left with a tool that may help at the margin but does not reverse the broader shift in search traffic distribution.
