Google tests AI 'Dive deeper' summaries inside Discover

Google is testing a new "Dive deeper" button in Discover that shows people an AI-generated summary of a topic before they ever reach a publisher's site. The feature currently applies to video cards, but if it expands to articles it adds another AI layer that can keep readers inside Google rather than sending them to the original source. For anyone who depends on Discover traffic, this is a fresh reason to make sure your content is structured so AI systems can extract and attribute it correctly, not just rank it.

What changed?

Google is testing a new feature called "Dive deeper" in Google Discover that gives you an AI-generated overview of a topic instead of sending you straight to a webpage, according to Android Authority. The experience can also surface links to related stories, community reactions and original reporting if someone wants to explore further.

Google Search VP Robby Stein announced the test on X, saying he was experimenting with a new way to make exploring a topic and discovering related web content easier in Discover, as reported by Search Engine Roundtable.

The mechanics work like this: tapping the button does not take you to a publisher's article. Instead it opens an AI-generated short topic overview with links to other articles and community reaction. Google's example starts with a weather video, beneath which sits an AI-generated summary carrying a warning that the information can contain mistakes. Tapping Dive deeper expands the experience into a longer overview, source cards and an "Explore more stories" section, per SEOteric.

This remains a live experiment rather than a full rollout. Google said it would test the experience on videos to start, and iterate on multiple designs in the weeks ahead to learn what works best, according to DEV Community.

Why does this matter for your business?

Discover has always been a meaningful traffic channel for publishers, and inserting an AI layer changes the handoff between discovery and the click. The experiment begins with video cards, but its significance extends beyond video: Discover has long been an important referral channel, and a Google-hosted summary could shift where user attention goes before a site receives a click, as SEORank notes.

The risk is straightforward: a reader can get enough context from Google's own summary to never need the original piece. For users, it could make Discover more convenient, but it may also mean fewer people actually open the publisher articles in their feeds. Coverage of the test framed it the same way: Google says the feature will make it easier to explore topics and discover related web content, but there's a potential downside for publishers, since users may get enough information from the AI-generated overview that they have less reason to click through, according to Panstag.

This sits alongside a broader pattern Google has already confirmed elsewhere in Search. Google has started folding AI Mode into AI Overviews in regular search, and AI Overviews can now expand into longer answers automatically on some queries, meaning Google's own answer takes up more of the screen before anyone reaches a blue link, as Envision It Agency reports. Dive deeper extends that same philosophy into Discover, a surface that previously sent readers straight to the source.

The good news is that links don't disappear, they just compete harder for attention. A link can remain visible while receiving a different share of clicks, which means your content still needs to earn a place inside the overview itself, not just in the "related stories" list below it.

What should you do now?

Treat Dive deeper the same way you'd treat any other AI summary surface: assume a growing share of your audience will see a machine-written version of your story before they see yours, if they see yours at all.

First, make sure your reporting and analysis are distinct enough to be worth clicking through to, even after someone has read an AI summary. Original data, direct quotes, named sources and specific numbers are harder for a generic overview to replace. Generic restating of other people's news is exactly the kind of content Dive deeper can substitute for entirely.

Second, keep your structure clean. The same clarity that helps a page earn a citation in AI Overviews or a ChatGPT answer, direct explanations, clear headings, strong topic framing, also improves your odds of being one of the sources pulled into Discover's "Explore more stories" or "community reactions" panels rather than being skipped over.

Third, watch your Discover performance in Search Console over the coming weeks. Because this is currently an experiment rather than a permanent feature every user will see, the effect on traffic won't show up everywhere at once. A sudden shift in Discover impressions or clicks, even on a small slice of your video or news content, could be an early signal that the test has reached your readers.

Fourth, don't assume this is only a publisher problem. Any brand that relies on Discover for product awareness, local news coverage or thought-leadership content should check whether their material is the kind of source Google's AI summary pulls from, or the kind it quietly replaces. This is the same question that applies across every AI surface now, from AI Overviews to ChatGPT to Perplexity: are you the thing the AI cites, or the thing it makes unnecessary? If you haven't checked where your brand currently stands across these answer engines, running a free audit with Sited is a quick way to see it.

Finally, keep an eye on whether Dive deeper expands beyond video. Google began the test with video content, though analysis of the code suggests variants tied to article cards are also being prepared, even though a public rollout hasn't yet been officially confirmed, according to Seafoam Media. If and when that happens, the stakes for written content in Discover rise considerably.

Frequently asked questions

Is Dive deeper live for everyone right now?

No. The test begins with video content, and Google hasn't specified the countries, languages or number of users involved, so this remains an experiment rather than a Discover-wide rollout.

Does Dive deeper replace Discover entirely?

Not currently. It adds an optional extra step. Tapping the button takes you to an AI-generated overview with links to other articles and community reaction, rather than removing publisher links altogether.

Will this cut my Discover traffic?

It's too early to say with certainty, but the direction of travel is clear. Google is testing a Discover feature that surfaces AI-generated topic overviews directly inside the feed, a change that could reshape how readers interact with publisher content.

Why is Google testing this now?

It mirrors what's already happening across the rest of Search. Google has started folding AI Mode into AI Overviews, and AI Overviews can now expand into longer answers automatically on some queries. Discover appears to be the next surface getting the same treatment.

What can publishers actually do about it?

Focus on content that's genuinely hard to summarise away: original data, direct sourcing and clear analysis. The structural habits that help you earn citations in AI Overviews and chatbot answers, direct explanations and well-labelled sections, are the same habits that help you stay visible inside AI-mediated surfaces like Dive deeper.
