Google is now automatically expanding AI Overviews to their full, uncollapsed state for certain search queries, eliminating the extra tap on "Show more" that previously separated a short AI summary from the complete synthesized answer. The change was first reported in late August 2026 after SEO professionals, including consultant Chris Long, flagged the behavior on social media, and it has continued rolling out through September.
Previously, AI Overviews typically appeared in a truncated form, requiring users to click "Show more" to see the full generated answer. Under the new behavior, Google's systems automatically expand the overview to its complete length for a subset of queries — without any user interaction — before a searcher scrolls to traditional organic listings below it.
A Google spokesperson confirmed the change, telling reporters: "For some queries, AI Overviews may dynamically expand for topics where our systems determine it's most useful for people." The company said its data shows "users find Search more helpful and engage deeper in follow-up exploration" as a result of the fuller, auto-expanded answers.
The expansion is applied selectively rather than universally — Google has not disclosed what share of queries are affected or the criteria its systems use to decide when to auto-expand. One notable detail: if a user has already scrolled past the AI Overview section before the expansion would occur, Google cancels the expansion so the page layout doesn't jump and disrupt where the user was reading.
The dynamic expansion is widely read by SEO professionals as a further step toward making AI Mode-style, fully synthesized answers the default search experience rather than a supplementary feature layered on top of traditional results. By showing more of the AI-generated answer automatically, Google reduces the likelihood that users need to scroll to — or click through to — the organic results and publisher websites listed beneath the overview.
For publishers and marketers, this compounds an existing trend: even when a website's content is used as a citation source inside an AI Overview, that visibility does not reliably translate into a click, since users can get a complete answer without leaving the results page. Search engine optimization teams have increasingly shifted focus toward citation visibility inside AI-generated answers rather than click-through rate alone, alongside continued investment in traditional ranking factors that still determine whether a page is eligible to be cited in the first place.
AI Overviews have expanded steadily since their initial rollout, extending to more query types, more countries, and more prominent placement within Search results. Google has paired this expansion with related changes, including efforts to standardize how sources are cited within AI-generated answers. The auto-expansion feature is the latest in a series of incremental changes that collectively increase how much of a user's informational need Google's AI can satisfy directly on the results page.
Google has not said whether auto-expansion will roll out to additional query categories or become the default behavior for all AI Overviews. SEO analysts expect the company to continue testing engagement and satisfaction metrics tied to the feature before any broader rollout, and publishers are being advised to monitor referral traffic from AI Overview-heavy query categories closely in the coming months to gauge the practical impact on their own traffic.
Does this affect all Google searches?
No — Google has confirmed the auto-expansion applies only to a subset of queries where its systems determine a fuller answer is most useful, without specifying which categories are affected.
Will this reduce traffic to websites?
SEO professionals broadly expect it to reduce click-through rates for queries where it applies, since users see a complete answer without needing to click "Show more" or scroll to organic results.
Can I opt my website out of AI Overviews?
Site owners can block Google's AI training and summarization crawler through robots.txt directives, though doing so may also affect a site's eligibility for other Google Search features.
The auto-expanding AI Overview is a small interface change with an outsized signal: Google continues to prioritize giving users complete answers directly on the results page, incrementally narrowing the space and attention available for traditional organic listings below it.
