Google Preferred Sources Affects AI Overviews
Google’s Preferred Sources lets signed-in users mark domains or subdomains so those publishers can be weighted more heavily across Top Stories, Discover, Google News and AI experiences (AI Mode and AI Overviews). The feature was tested in June 2025, rolled out for English searches in December 2025, expanded to multiple languages (including German) by late April 2026, and extended into AI experiences in May 2026. Publishers can embed an official Preferred Sources button or share deeplinks to encourage selection, but final choices remain user-driven and Top Stories ranking stays algorithmic. Google reports users click about twice as often after marking a site preferred. Adoption grew from over 200,000 distinct sites by end‑April 2026 to over 345,000 by end‑May 2026, and Google later reported more than 600,000 preferred sources. Discover gained a free-text control and Google News on Android will add customizable, attributed audio briefings.
Major platform (Google) feature rollout that changes publisher visibility in search results and AI-generated overviews, affecting SEO, traffic patterns and publisher distribution strategies.

Google Adds Preferred Sources to AI Mode and Overviews
Google has integrated its Preferred Sources feature into AI Mode and AI Overviews, surface labels for preferred sources, and introduced a new Highly Cited label plus two source carousels in AI-powered search results. The carousels highlight (1) sources on fast-moving news topics and (2) social- or forum-sourced answers (e.g., from Facebook, TikTok, Reddit). Google says users are twice as likely to click a preferred source and that more than 345,000 unique sources have been marked preferred. Product Manager Duncan Osborn framed the update as bringing preferred sources into AI search, while Google’s EMEA head Debbie Weinstein cited large usage figures (about 2.5 billion AI Overviews users and over 1 billion AI Mode users monthly). Google also noted it will call out when a result used a Highly Cited source and signalled further search-result updates are coming.
Google Adds 'Preferred Sources' to German Search
Google has launched its "Preferred Sources" feature for Google Search in German, enabling users to prioritize their favorite news outlets in Search results and the Top Stories/Headlines area. The feature, introduced globally in 2025 and now available in more languages including German, lets users pick from a list of over 200,000 international news sources via a star button in the "Headlines" section. Google says users who mark a source as preferred click that source roughly twice as often, which Google frames as a way to help publishers drive traffic and strengthen reader relationships. Publishers can surface deep links to source settings or add follow/subscription buttons. The rollout comes amid ongoing debates about Google's AI summaries and their impact on publisher traffic and regulatory scrutiny.
Google Tests AI Article Summaries; Preferred Sources Worldwide
Google is reshaping how users discover news by rolling out Preferred Sources for personalized Top Stories and by testing AI-generated article summaries in News, including content from Der Spiegel, The Guardian, The Washington Post, The Times of India, and El País. The AI Overviews and AI Mode are being integrated into search, offering context-rich summaries, inline links, and even audio briefings, sometimes supplemented by short videos from TikTok or YouTube. Publisher concerns focus on reduced clicks and potential reliance on Google-owned properties for ads, triggering debate among publishers and regulatory scrutiny. Google is conducting a pilot with major publishers, expanding link presentation in AI Mode and integrating a Gemini-driven system to highlight links from subscribed publishers in the Gemini app. The European Commission has opened an antitrust probe into Google's AI training data use, with penalties up to 10% of worldwide turnover.
