Google tests a "Dive deeper" button in Discover that opens an AI topic overview
Robby Stein, VP of Product for Google Search, announced the test on X on 18th Sep. The post went up at 20:13 UTC.
"Today we're experimenting with a new way to make exploring a topic and discovering related web content easier in Discover," he wrote.
Tapping "Dive deeper" opens "a short topic overview with prominent links to related stories, community reactions & original reporting".
The test starts on videos. Stein said Google will "experiment with multiple designs in the weeks ahead".
The post names no country, language or share of users. It is an experiment, not a launch.
Search Engine Journal described Stein's example image. A KCRA 3 weather video from YouTube sits in the feed with a short summary below it.
The summary carries the label "Generated with AI, which can make mistakes". The button sits under it.
The second screen has a Google logo, the same video, a longer summary and a row of source cards. The first card is from kcra.com.
A third screen is headed "Explore more stories". It groups short summaries under sub-topic headlines, each followed by source links.
Search Engine Roundtable makes the publisher's point. The button opens a Google page, not an article, and the publisher links sit inside that page.
The feed already carries AI Summaries and AI-generated topic headlines. This test adds a second Google screen between a card and the coverage behind it.
No study measures its effect on clicks yet, and Google has given no figures.
