The answer at the top of the page got bigger
On some searches Google now opens the AI summary at the top of the results page in full. Before, part of the summary appeared with a button that expanded it; in the new layout the full summary comes first, a question box sits under it, and then the list of links. Search Engine Roundtable reported the change first.[1]
Seen from the street, the difference is this: the one quantity a user can measure is the amount of scrolling it takes to reach the familiar list of links. Which searches trigger the behaviour has not been stated, and the reporter could not repeat even his most consistent query the same way across searches and browsers. Someone who cannot predict when a layout turns on cannot learn it by trying either.[1]
The placement decision now covers size too
This column's piece of 28 July argued that how often the summary appears in searches measures Google's placement decision. Opening it automatically continues that line: the decision now sets not only whether the summary appears but how much room it takes. There is a weaker reading of the same observation: the behaviour may be in trial and may be pulled back before it spreads.[1], [2]
Google spokesperson Jennifer Kutz says the summary expands dynamically on topics the company's systems judge most useful, and that the company's research shows users find Search more helpful. Kutz adds that expansion is cancelled once a user has begun scrolling to see content below the summary. That second detail is a real recovery path on the product side: it protects the reading position. As long as the criterion stays unwritten, a user still cannot know in advance which layout will appear.[1]
The signal worth waiting for
The question left open is this: if the behaviour becomes permanent, will the queries that trigger it be stated in writing? This change becomes judgeable in everyday use only if the criterion is published or a setting that switches the layout off is shipped. Without either, scrolling is all a user is left holding.[1]
