Google tests ‘Dive deeper’ in Discover — what publishers and SEOs need to know
Google has started testing a new Discover feature called “Dive deeper” that surfaces AI-generated topic overviews directly inside the Discover feed, a change that could reshape how readers interact with publisher content. Search Engine Land first reported the test, citing Robby Stein’s announcement on X that the feature will offer “a short topic overview with prominent links to related stories, community reactions & original reporting.”
What the test does and how it looks
The “Dive deeper” button appears on a Discover card (Google’s example starts with video cards). When tapped, it opens a compact, Google-generated overview of the topic plus a row of linked source cards and grouped follow-up angles. In the mockup shared by Google, the overview places brief summaries and publisher links under subtopic headings, giving the user an on-device “deeper look” without immediately navigating away from Google’s interface.
Key points at a glance
- Google announced the test via a short X post: “Today we’re experimenting with a new way to make exploring a topic and discovering related web content easier in Discover,” Robby Stein wrote, adding that the test will begin with videos and that Google will “experiment with multiple designs in the weeks ahead.” (Source: Search Engine Land.)
- Independent researchers found client-side flags suggesting the button could be enabled for both video and article AI summary cards, indicating the test may expand beyond videos.
- Publishers immediately raised concerns that a Google summary plus truncated link cards could reduce click-through rates to original reporting.
Why publishers and SEOs should care
Discover has become a major source of referral traffic for many publishers. Multiple data sets previously showed Discover accounting for a large share of Google-driven referrals, and publishers that relied on that distribution have already reported declines in volume as Google adds generative features. The new “Dive deeper” treatment adds another Google-controlled tap target that, by design, can keep users inside Google’s interface while presenting publisher links lower in the visual hierarchy.
The concern landed quickly. As PPC.land summarized the publisher reaction, Nicola Agius, SEO and Discover director at Reach plc, wrote: “Google just unleashed its latest attack on publisher traffic – this time, Discover is in the firing line.” That blunt assessment captures the immediate fear: if users read the overview and stop there, publishers lose the visits and potential ad or subscription revenue tied to them.
Potential short-term effects
There are several immediate unknowns that will determine impact: how frequently the button appears, which markets and languages are included in the test, whether the original publisher is guaranteed a link in the overview, and whether impressions or clicks within the overview are reported separately in Search Console. Google’s existing generative AI performance report for Discover provides impression counts but not click-level clarity for these experimental surfaces, making early measurement difficult.
Longer-term implications for content strategy
If Dive deeper rolls out broadly, publishers and SEOs should expect continued pressure on click-through rates from Discover positions that carry AI summaries. That may accelerate two trends: a shift toward content and formats that encourage user actions beyond passive reading (for example, interactive tools, gated content, or subscription prompts within the article), and a stronger emphasis on brand signals that may persuade users to tap a publisher’s image or headline rather than Google’s CTA.
Actionable recommendations for publishers and SEOs
- Audit Discover performance regularly. Use the generative AI performance report in Search Console for trends in impressions, and supplement with page-level analytics to track referral and click-through behavior.
- Prioritize tap-worthy assets. Ensure your publisher cards in Discover have strong imagery and headlines that communicate unique value. Where possible, test alternative meta titles and images to increase the appeal of the publisher tap target.
- Strengthen first-paragraph value. If users see summaries in Discover, the first lines of your articles should offer immediate, exclusive value that encourages clicks — facts, data points, or a clear call to action that can’t be replicated in a short AI overview.
- Advocate for transparency. Publishers should track how often their stories appear inside Dive deeper and press for clear reporting from Google about how links in AI-generated overviews are counted and attributed.
- Explore diversified acquisition channels. Reassess reliance on Discover and increase investment in channels you control (email, direct, social) and in search signals that feed other platforms or syndication options.
What to watch next
Google said it will experiment with multiple designs and expand testing beyond videos as it iterates. Independent researchers have already found flags that suggest article cards are part of the planned footprint, and some early builds appear to include the client-side code for multiple entry points. If you depend on Discover traffic, monitor mentions of the feature on industry channels and check your own Search Console and analytics dashboards for any new patterns in Discover impressions and clicks.
For now, the clearest step is measurement and preparation. Track changes, protect owned channels, and optimize your site experience so that when — or if — users do tap through, the visit delivers measurable business value.
