Google has expanded the visibility of Preferred Sources to its AI Overviews, marking the next phase in the company’s effort to let users influence which websites appear most prominently in search results. The update, which follows the global rollout of Preferred Source selection across all languages, now ensures that user-selected preferred websites receive dedicated visual treatment inside the AI-generated summaries that appear for many search queries. This is not merely a cosmetic change; it redefines how much control individual users have over the algorithmic curation of their search experience.
Preferred Sources, a feature that allows logged-in Google users to designate specific websites as priority results, was originally introduced as a way to personalize the search journey. By selecting trusted or frequently used sources, users could ensure that content from those domains ranked higher in their results. Until now, however, those preferences did not extend into the AI Overviews module. With this update, when a user has designated certain sources as preferred, those sources will be flagged within AI Overviews wherever they are cited. The visual treatment makes it immediately clear which results match the user’s personal preferences, providing a layer of trust and familiarity inside a space that is otherwise fully algorithmically generated.
How Preferred Sources Appear Inside AI Overviews
The mechanism is straightforward. Users can set their preferred sources through the dedicated preferences page at google.com/preferences/source. Once configured, any AI Overview that references content from one of those sources will display a visual indicator, typically a small label or icon, marking it as a Preferred Source. This does not guarantee that the preferred source will be included in every overview, because the AI model selects content based on relevance and authority, but when the preferred source does appear, the user will see it highlighted. The effect is a hybrid search environment: the generative AI still assembles the summary, but the user’s human judgment about which sites they trust is overlaid on top.
Google has also expanded the labeling of “Highly cited” sources within the same ecosystem. These are pages that many other sites reference, functioning as a credibility signal that helps users identify original reporting or authoritative content. The Highly cited label now works alongside Preferred Sources to give users two distinct signals: one based on personal preference, another based on broad web-wide citation patterns. Together, they provide a more nuanced reading of why a particular source appears in an overview.
What Is a Preferred Source and How Does It Change Search Personalization
A Preferred Source is a website that a user deliberately selects as a priority result in Google Search. Once selected, content from that site receives a visual marker and is promoted in the user’s search results. The feature is available to anyone with a Google account and can be configured at any time. In the context of AI Overviews, the Preferred Source label appears directly inside the generated summary, giving the user immediate confidence that at least one cited source aligns with their personal editorial trust. This changes search personalization because it introduces explicit user curation into a space that has been dominated entirely by algorithmic inference. Instead of Google deciding which sources are most authoritative for a given query, the user can predefine that authority themselves.
New Carousels for Trending Topics and Social Content
Beyond the AI Overviews update, Google has launched two new carousel modules in the standard search results. The first addresses “topics with growing attention” — rapidly emerging subjects that are generating fresh interest. In this carousel, Preferred Sources are once again highlighted, ensuring that users see their selected domains even inside a module designed to surface fast-moving, zeitgeist-driven content. The second carousel is dedicated to sources from social media and forums, and it appears specifically for queries where the opinion or experience of other people is likely to be valuable. For searches such as product recommendations, travel advice, or troubleshooting tips, this carousel pulls in content from platforms like Reddit, Quora, and other discussion-based sites. The inclusion of this carousel signals Google’s recognition that for certain query types, peer-generated content carries as much weight as professionally published material.
Availability and Global Reach
All of these features are available immediately. Google has placed no restrictions on language or country for any of the three updates: Preferred Sources in AI Overviews, the trending-topics carousel, or the social-media and forums carousel. This means that any user, anywhere in the world, who has configured preferred sources will see them highlighted in AI Overviews as long as those sources are referenced. The absence of phased rollout suggests that the underlying infrastructure was prepared during the earlier worldwide launch of the Preferred Source preference system itself, and that extending it to AI Overviews and carousels was a matter of flipping additional switches rather than building new capabilities from scratch.
The expansion of the Highly cited label further reinforces Google’s broader strategy of offering users multiple signals about source quality. Rather than relying on a single monolithic authority score, Google is now layering personal preference, citation-based credibility, and topical timeliness into the same results page. For publishers, this creates a more complex optimization environment. Earning a Preferred Source designation requires individual users to actively select a site, which depends on brand loyalty, consistent quality, and user trust. Earning a Highly cited label depends on being referenced by many other domains, which rewards original reporting and unique data. Both signals now carry weight inside AI Overviews, meaning that publishers who invest in both user trust and peer citation stand to gain the most visibility.
The introduction of the social-media and forums carousel also has implications for content strategy. For years, Google has faced criticism that it underrepresents community-generated content in favor of polished, SEO-optimized articles. This carousel is a direct response, elevating discussions, personal anecdotes, and forums for queries where human experience matters. For search marketers, this means that a presence on platforms like Reddit, specialized forums, or even community boards can now generate direct traffic through a dedicated carousel, rather than competing in the same organic results as traditional articles.
The broader trend is unmistakable. Google is moving toward a search experience that blends generative AI, personalized preferences, multiple credibility signals, and diverse content formats within a single results page. The old model of ten blue links is being replaced by a modular, adaptive interface that shifts depending on the query, the user, and the available content. For publishers and SEO professionals, the key takeaway is that authority is no longer a single metric. It is now composed of personal user preference, network citation, topical freshness, and platform-specific relevance. Optimizing for all four will be the defining challenge of search visibility in the months ahead.
As these features reach every user worldwide without language or regional gatekeeping, the competitive landscape for search visibility has shifted. The question is no longer simply whether a site ranks well. It is whether a site earns the trust of individual users enough to be selected as a Preferred Source, whether it earns the respect of other publishers enough to be Highly cited, and whether its content fits the emerging modular formats that Google is building into the fabric of search. The updates announced today are not incremental. They are structural. And they are live now.
