Google confirmed on August 28, 2026 that it now dynamically expands AI Overviews to full length for some queries, removing the Show more control and pushing organic results further down the page. Google hasn't disclosed which queries qualify or what share of searches are affected. The practical response is to write pages built to be quoted whole, not skimmed for a snippet, since a citation inside the expanded box now matters more than a ranking underneath it.
What did Google change about AI Overviews on August 28, 2026?
Google confirmed on August 28, 2026 that AI Overviews now dynamically expand to their full length for some queries, replacing the familiar Show more control with a complete answer shown by default. Search Engine Land broke the confirmation, after the SEO consultant Chris Long spotted the change a day earlier and posted examples on X of an AI Overview opening fully with no click required.
The expanded state looks and behaves like Google's AI Mode transplanted directly into classic Search. It can surface an Ask anything prompt box inline, and because the answer runs longer, it occupies more vertical space above the fold. Google builds in one courtesy: if a searcher has already scrolled past the Overview, the system cancels the automatic expansion so the reader doesn't lose their place on the page.
A Google spokesperson framed the change as a usefulness call made by the system, not a manual toggle: 'For some queries, AI Overviews may dynamically expand for topics where our systems determine it's most useful for people.' Google added that internal research ties the fuller format to searchers finding Search more helpful and pursuing deeper follow-up questions, which is the company's usual justification for giving AI answers more room on the page.
Who does the dynamic expansion affect?
Everyone who ranks organically for a query Google decides deserves the full treatment. Google did not publish a list of qualifying topics, a percentage of affected queries, or a threshold for what counts as useful enough to expand. The only stated criterion is a system judgment call, applied query by query.
That vagueness is itself the operating condition. A brand comparison query, a how-to question, or a local service search can each tip into the expanded state without warning, and a page that currently earns a click under a truncated AI Overview can lose that click the moment the same query graduates to the full-length version. Treat every ranking position as provisional rather than assuming today's SERP behavior holds tomorrow.
Publishers who already see heavy AI Overview coverage on their category terms should expect to feel this first, since those are the queries Google's systems have the most confidence rewriting into a complete answer.
| Element | Before: Show more control | After: dynamic expansion |
|---|---|---|
| AI Overview length | Short summary, truncated by default | Full answer shown automatically, no truncation |
| Show more button | Present, requires a click to expand | Removed for queries Google flags as qualifying |
| Ask anything box | Not shown inside classic Search results | Displayed inline, mirrors the AI Mode interface |
| Organic results position | Visible within roughly one scroll on most queries | Pushed further down the page |
| Who controls expansion | The reader, by clicking Show more | Google's system, canceled only if the reader already scrolled past |
What does the before-and-after actually look like?
Compare the SERP mechanics on either side of the August 27 to 28, 2026 rollout window. Before the change, an AI Overview showed a short summary with a Show more control, and organic results stayed within roughly one scroll for most queries. After the change, qualifying queries render a full answer automatically, with no click and no truncation, and the traditional ten blue links move noticeably further down.
The table below lines up the two states element by element, dated to when Search Engine Land and Google confirmed the behavior.
How should you respond to auto-expanding AI Overviews?
The click that used to come from ranking under a short AI Overview is harder to earn now that the box itself does more of the reader's job before they ever reach the blue links. Ahrefs' Ryan Law puts a number on the underlying trend: the presence of an AI Overview already correlates with a 58% lower average click-through rate for the page ranking first, measured before this expansion pushed results even further from view. A longer, auto-opened Overview only widens that gap for pages that aren't the one being quoted.
That reframes the goal. Ranking under the box is a consolation prize; being the source the box cites, by name, inside the answer, is what still converts an impression into a visit. A few things follow from that.
Write the direct answer to the question in the first sentence or two of the piece, not buried after three paragraphs of throat-clearing, so the model has a clean sentence to lift. Attach a real, dated stat, comparison table, or original data point to every piece you publish, because that is the asset an answer engine actually has a reason to quote rather than paraphrase. Refresh or retire pages on a schedule instead of leaving them static, since Google's own framing of this change leans on freshness and usefulness signals that a three-year-old post rarely clears. Publish enough coverage across a topic cluster that you're a plausible citation on the comparison query, the how-to query, and the local or vertical variant, not just the head term.
None of this is about tricking the ranking system into expanding your query more often. Google hasn't published the mechanism, and guessing at it is a waste of a content calendar. The lever that's actually in a publisher's control is whether the page is worth citing when the system does decide to expand.
What should you track after this rollout?
Rank position tells you less than it used to. What matters now is Citation Share, the percentage of relevant AI answers in your category that name you, alongside Answer Presence across the fuller set of questions your buyers actually ask. Watch Share of Voice against the two or three competitors who keep showing up in the same expanded boxes you do, and track raw Citation Count per day as a volume signal underneath the share number.
LeadHaste, Omnicite's own site, ran this playbook on itself: zero to 1 million impressions, more than 200 AI citations, and Domain Rating moving from 1 to 24, in four months. That's one data set, over one specific stretch of time, not a promise about what any other domain will see. It's evidence that the response to an expanding, more selective AI Overview is coverage and citability, not a defensive crouch.
Key takeaways
- Google confirmed on August 28, 2026 that AI Overviews now auto-expand to full length for some queries, removing the Show more control.
- Google has not disclosed which queries qualify or what share of searches are affected, only that its systems judge the fuller format 'most useful.'
- The expanded box mirrors AI Mode's interface, including an inline Ask anything prompt, and pushes organic results further down the page.
- An AI Overview already correlates with a 58% lower average click-through rate for the top organic result, per Ahrefs; a longer, auto-opened box widens that gap.
- The response is citability, not gaming the system: a direct answer up top, a dated stat or table, and a refresh cadence competitors can't match.
- Track Citation Share, Answer Presence, and Share of Voice going forward. Rank position alone no longer tells you whether you're the one being quoted.

Frequently asked questions
When did Google start dynamically expanding AI Overviews?
Google confirmed the change on August 28, 2026, after the SEO Chris Long first spotted it on August 27, 2026 and posted examples on X.
Does the Show more button still exist in AI Overviews?
Yes, but not for every query. Google removes it on queries where its systems determine the fuller, auto-expanded answer is most useful, and keeps the standard short-form Overview elsewhere.
Does this happen on every Google search?
No. Google has said the expansion applies to some queries only, without naming which topics or what percentage of searches qualify.
Does the expanded AI Overview hurt organic click-through rate?
It's likely to. Ahrefs already measured a 58% lower average click-through rate for the top organic result on queries with an AI Overview, before this expansion pushed results further down the page.
What's the difference between this and AI Mode?
AI Mode is a separate, fully conversational search experience. This change brings AI Mode's look and interface, including the Ask anything prompt box, into the standard Search results page for qualifying queries.
What should a content team do differently because of this change?
Lead every page with a direct answer, attach a real dated stat or comparison table, and keep publishing and refreshing at a pace that keeps the page eligible to be the one an AI Overview quotes.
