On August 28, 2026 Google confirmed that AI Overviews can now expand automatically into a longer, AI Mode-style answer for some queries, removing the manual Show More button and loading the Ask Anything box by default. The expansion cancels if the searcher has already started scrolling toward the results. Earlier the same month, Google began rolling out generative UI, which builds custom visual layouts and interactive tools inside the answer, from AI Mode into AI Overviews. Neither change is an algorithm update.
The change is easy to miss because nothing about the result page announces it. The same query that returned a three-line overview in July can now return a full AI Mode-style answer, and the only visible difference is how far you scroll before the first link.
A Google spokesperson told Search Engine Roundtable that AI Overviews "may dynamically expand for topics where our systems determine it's most useful for people." This is a layout change, not an algorithm update, and that matters for how you diagnose it. Nothing about your page changed, nothing about how it is ranked changed, and a site that tracks position will see no movement at all while its click-through rate falls.
“On a growing share of queries the citation inside the overview is the impression, and the click is a bonus.”
The generative UI rollout compounds it. Where the answer builds its own comparison table or interactive tool, the reader gets something a results page never offered, which raises the bar for what a click has to be worth.
Why it matters for your business
A longer answer by default means the first organic link sits further down the page than it did in July, on queries you have not changed and did not lose. Expect the click-through decline to show up as a ranking problem in your reporting when it is a layout problem, and expect it to be uneven: informational queries absorb the expansion, transactional ones mostly do not.
The useful response is not to chase the ranking. It is to accept that on a growing share of queries the citation inside the overview is the impression, and the click is a bonus. That reframes what a good page looks like. You want to be the source named in the expanded answer, which means being quotable in two or three sentences, and you want the part of your page a user would still click through for, the calculator, the pricing, the data, to be obviously not reproducible inside the overview.
Measure citations in the overview as a first-class metric. If you are still reporting only sessions, this change is invisible to you and your traffic will look broken for no reason you can name.
