Google Tests a Top Stories Carousel Inside AI Overviews

Google is testing a Top Stories carousel inside AI Overviews, putting publisher links directly under the AI-generated summary rather than below the search page. The carousel, first spotted in a live search session on June 27, surfaces major outlets like The New York Times and Yahoo and prioritizes the Preferred Sources a user has already picked in Google settings. Google pre-announced the design in a May 27 blog post, and the June 27 test is the first public confirmation that the rollout has begun.

Google’s blog said the carousel would appear “for some searches when you have a question about a developing topic.” The June 27 sighting suggests the rollout is now reaching real searchers, though only a subset. For publishers, it is the first real click path that runs through the AI Overview, into the publisher’s site.

What Searchers Are Seeing Right Now

SEO specialist Lily Ray posted the first public screenshot of the new interface on X at 2:27 a.m. UTC on June 27, asking simply, “Top Stories inside AI Overviews since when?” The post tagged fellow search analysts Barry Schwartz and Glenn Gabe. It drew 4,451 views, 30 likes, two retweets, and eight replies within hours.

Schwartz, who runs Search Engine Roundtable and the New York consultancy RustyBrick, said he replicated the finding in his own browser. “The screenshot on the right shows a Top Stories carousel with content from The New York Times, Yahoo and others,” he wrote. He did not see his own Preferred Sources in the test he ran, and noted that he “assumes they can show up if there is content that matches your query to your preferred sources.”

From a May Tease to a June Rollout

Google’s own May 27 announcement of Preferred Sources in AI Search is the source of the design. “Now we’re bringing your Preferred Sources directly into our AI experiences, and launching new features to help you discover original content, creator insights, and unique perspectives,” the post reads.

you’ll be able to easily spot links in AI responses from the sources you’ve already selected.

That was Duncan Osborn, Product Manager at Google Search, speaking to the rollout details and the product lead quote. The Preferred Sources feature is “now available globally and in all languages,” per that same report.

The Carousel and Its Developing-Topic Trigger

A “Top Stories” carousel inside an AI Overview sits where the old answer box once stood: directly below the AI summary, scrolling horizontally. The Schwartz screenshot showed The New York Times, Yahoo, and other outlets in the row. The browser test of the new AI Overview carousel matched Google’s May post, which said the carousel would also highlight the user’s Preferred Sources so the same row can mix default top stories with the publications a user has chosen to favor.

The trigger is narrow on purpose. Google says the carousel fires only for “developing” topics, the kind of fluid news story where the baseline facts shift by the hour. Stable queries, evergreen explainers, and product searches do not pull the carousel. That is the search giant drawing a line between AI answers that need a time stamp and AI answers that do not.

A snapshot of the rollout’s early signal:

• May 27, 2026: Google announces Preferred Sources in AI Overviews and a developing-topic carousel in a blog post.
• June 27, 2026: Lily Ray flags the first live screenshot on X at 2:27 a.m. UTC.
• Over 345,000 unique sources selected by users as Preferred Sources, per Google.
• Twice as likely to click through on a Preferred Source than a non-preferred link, per Google.
• Globally available and in all languages, per Search Engine Land’s coverage of the May 27 announcement.

Preferred Sources Picks the Carousel’s Winners

Preferred Sources is the lever that decides which publishers get the slot. A user opts in by visiting Google’s “source preferences” page in Search personalization settings and naming the sites they want to see more of. The system then highlights links from those sites in Top Stories, in AI Overviews, and in AI Mode.

The May 27 blog said “any website that publishes fresh content is eligible.” The scale of the opt-in matters because the carousel is personalized. Google said in May that “people are twice as likely to click through to a Preferred Source,” and Search Engine Land’s coverage put the number of selected sources at “over 345,000 unique sources.” That is a step up from around 90,000 at the global rollout in December 2025, the yellowHEAD 2026 search changes report notes.

AI visibility is no longer only about being cited. It is about becoming a source people recognize, trust, and actively want to see.

Geertrui Laleman, Senior AI Search Optimization Specialist at Semrush, made the case to yellowHEAD’s 2026 search changes report. Ranking for a keyword still matters, but the carousel puts audience loyalty ahead of backlink weight. A publisher’s reach inside AI Overviews now depends as much on which readers have selected the site as a Preferred Source as on which sites link to it.

What Changes for Publishers This Week

The practical move is to push existing readers to add the publisher as a Preferred Source. Google has published documentation explaining how to do that and a button template publishers can drop into a site or newsletter. The audience most likely to opt in is the publisher’s own: newsletter subscribers, social followers, and return visitors. Each one is a vote that makes the publisher more likely to appear in the carousel when that user searches.

The Search Console gives publishers a way to track whether the bet pays off. On June 3, Google announced new Search Generative AI performance reports in Search Console that break out impressions inside AI Overviews, AI Mode, and generative Discover features, by page, country, and device. The reports are rolling out to a subset of sites first.

Three publisher-facing signals landed in the Google search page in the space of six weeks:

• The Preferred Sources label, rolled out in AI Overviews and AI Mode on May 27, 2026.
• The developing-topic Top Stories carousel inside AI Overviews, first publicly spotted on June 27, 2026.
• The Highly Cited badge, expanded to more web article links in the same window.

The Limits of the Reprieve

The reprieve is real, but it is narrow. The carousel fires only on developing topics, only when the user has selected Preferred Sources, and only inside AI Overviews and AI Mode. The AI summary still sits on top, the carousel still sits below it, and the click path still starts inside an AI-written answer. Publishers get a slot in the row underneath the summary, not in the summary text itself. For a sense of the parallel risk, see the Munich ruling on AI Overview liability.

The legal exposure of AI Overviews is also still open. A Munich court recently ruled that Google is directly liable for false claims surfaced in AI Overviews, a precedent publishers are watching as the carousel widens the surface where their links appear. The click-through gain and the liability cost now travel together, and publishers are taking on both at the same time.

Frequently Asked Questions

Does the Top Stories carousel replace the AI summary in Google Search?

No. The carousel sits below the AI-generated answer, not in place of it. The summary is still the first thing a user reads; the carousel is the row of publisher links that follows.

How does a publisher get into the new Top Stories carousel inside AI Overviews?

Carousel placement is driven by a user’s Preferred Sources. A publisher’s link is more likely to appear in the carousel for a given searcher if that searcher has added the publisher as a Preferred Source in Google’s personalization settings. Google’s own documentation walks through the steps and offers a button template for sites.

Is the Top Stories carousel rollout global?

Preferred Sources is available globally and in all languages, per Search Engine Land’s coverage of Google’s May 27 announcement. The carousel itself is appearing for a subset of searchers as of late June 2026.

Does this change how AI Overviews handle publisher content overall?

It adds a direct link path through the AI summary, into the publisher’s site. The Preferred Sources label and the Highly Cited badge are two more publisher-facing signals that landed in the search page in May and June 2026.

What is a Preferred Source in Google Search?

A Preferred Source is a website a user has chosen to see more of in Google Search. The setting lives in Google’s personalization menu, and the user’s picks are highlighted in Top Stories, in AI Overviews, and in AI Mode responses.
