## Google tests an AI-written 'Dive deeper' summary inside Discover, starting with videos

Status: Confirmed  |  Topics: ai-overviews-ai-mode, organic-search-core

Google is testing a 'Dive deeper' feature in Discover that replaces a direct article click with a short AI-generated topic overview, plus links to related stories and community reactions. Google Search VP of Product Robby Stein confirmed the test on September 18, 2026, calling it an early design and acknowledging the AI-generated summary 'can make mistakes.' The test starts with video results before any wider rollout.

In plain terms: Discover is the feed of article recommendations Google shows in its mobile app and on Android home screens, historically a reliable click-through source for publishers. This test puts an AI-written summary in front of that click on video stories, the same substitution AI Overviews already made in regular search results.

Why it matters: A summary that answers the query inside Discover, before any click, moves one more high-traffic surface toward the same AI-answer pattern already reshaping web search referrals.

Our take: I found in Google's billions-of-clicks claim that Google's own AI-traffic figures can't be checked against a site's own data. Dive deeper extends that same unverifiable layer to Discover, a surface publishers have relied on for direct referral clicks, so the traffic effect here will be just as hard to isolate in Search Console alone.

## Google Web Guide's 'classic search' button doesn't return classic search results

Status: Observed  |  Topics: ai-overviews-ai-mode, organic-search-core

Search Engine Roundtable reported on September 20, 2026 that Google's Web Guide, an AI/web-search interface, ships a 'Classic search' button that fails to exit Web Guide: clicking it reloads the same Web Guide results instead of returning to standard search. The report cites on-the-record observations from SEO practitioners Damien Andell and Glenn Gabe; Google has not issued a statement on the bug.

In plain terms: Web Guide is a newer Google interface that blends AI-generated answers with search results, distinct from the classic blue-links page. This bug means once a user opens it, the one button meant to get back to normal search results doesn't work, and Google hasn't acknowledged or fixed it yet.

Why it matters: A dead-end navigation button on a brand-new AI search surface is a small bug with a bigger tell, that Web Guide is still rough enough that other unverified behavior, like ranking or citation logic, likely has the same maturity gap.

Our take: A broken exit button matters less on its own than as a signal of where Google's attention is right now. Web Guide is still shipping surface-level bugs weeks after its wider rollout, worth watching for anyone trying to judge how stable its ranking and citation behavior actually is before building process around it.
