Google will automatically expand AI Overview summaries at the top of search results for some queries, according to Search Engine Roundtable. The update replaces the previous "Show more" button with a full overview that appears before the list of links, requiring additional scrolling.

The criteria for expansion are not publicly defined. A Google spokesperson, Jennifer Kutz, said the system determines when an expanded overview is most useful and that research shows users find Search more helpful and engage in deeper follow-up exploration. If a user has already scrolled past the AI Overview, expansion is cancelled to preserve reading position.

The change follows the introduction of AI Overviews earlier in 2024, which initially appeared only after a user clicked "Show more." Google's search interface has been gradually incorporating more AI-generated content.

The rollout timeline and the full list of queries that trigger expansion have not been disclosed, leaving the scope of the feature uncertain.
