Google is testing a “Dive deeper” button in Discover that opens a concise topic overview with links to related coverage.

Robby Stein, VP of Product for Google Search, announced the experiment on X Friday. The test begins with video content.

In the example posted by Stein, the overview displays other coverage as links inside the summary, giving users a quick way to explore a topic without leaving Discover.

The goal is to surface a curated snapshot of a topic—starting with a short video—followed by a list of relevant articles. This design mirrors the way people naturally browse topics on the web, but it keeps the experience within Discover, reducing friction for users and giving publishers a fresh channel for visibility.

Why This Matters For Your Business

The introduction of a “Dive deeper” button could reshape how businesses capture attention in Google Discover. By offering a ready‑made overview that starts with a video, brands can position themselves at the top of a user’s exploratory journey, potentially boosting click‑through rates and generating new AI‑driven citations. For companies that rely on Discover for traffic, this experiment means that simply publishing high‑quality video content and ensuring it’s indexed could open a new pathway to visibility. As Discover continues to prioritize visual and conversational content, the ability to surface a topic overview directly on the feed may become a key lever for driving engagement. Marketers should monitor the rollout closely, test their own video assets, and optimize metadata so that their content appears in the emerging overview snippets. Early adopters who align their content strategy with this format may see a measurable lift in organic discovery and brand authority.
