TL;DR Summary:
AI Mode Tests: Google is experimenting with new query expansion features in AI Mode that change how users refine searches before clicking results.Faster Follow-Ups: One test lets people select multiple answer options instead of typing, making follow-up questions quicker and more click-based.Shopping Refinements: Another test adds refinement prompts between product listings, helping users narrow searches without restarting.Still Unconfirmed: Google has not said when or whether these changes will roll out widely, so the interface should be treated as temporary.Why does Google AI Mode keep changing how it asks follow-up questions? Google is running new tests inside AI Mode that add fresh ways to narrow down a search, spotted on September 14, 2026. This matters now because Google AI Mode query expansion tools shape how you refine results before you even click a link.
What Sachin Patel Found in Google AI Mode Query Expansion Tests
Sachin Patel spotted the new interface elements and posted them on X and on Search Engine Watch. He shared screenshots showing two separate features. One lets you pick from several answer options at once instead of typing out a response. The other shows refinement prompts placed between free product listings in search results. Barry Schwartz covered the find on September 14, 2026, and noted these tests fit a pattern Google has followed for some time.
Multi-Selection Questions Change How You Answer AI Mode Prompts
The first feature adds multi-selection to AI Mode’s follow-up questions. Instead of writing an answer, you tap the choices that fit your search. This speeds up the back-and-forth Google uses to understand what you actually want. For anyone tracking Google AI Mode query expansion, this signals Google wants less typing and more clicking during a search session.
Query Refinement Prompts Appear Next to Product Listings
The second feature places refinement options between free product listings in the search results page. These prompts help you adjust your search terms without starting over. Schwartz shared an image of this layout from Search Engine Watch, though Google has not confirmed how many users see this version or how long the test has run. This form of Google AI Mode query expansion sits closer to shopping searches than general questions. Because these interface shifts can surface or bury content without warning, some site owners are turning to platforms like Nuwtonic SEO to monitor how their pages actually appear across these evolving AI search formats, rather than relying on guesswork as Google iterates.
Paginated Responses Join the List of AI Mode Experiments
These two features join paginated responses, a format Google tested earlier where AI Mode splits long answers into separate pages instead of one long block of text. Schwartz points out he is not certain how new any of these three features actually are. He also expects Google to keep running more tests like this across AI Mode. That pattern matters because it shows Google treats query refinement as an active area of development, not a finished product.
What This Means for Anyone Watching Google AI Mode Query Expansion
Google has given no official confirmation about a wider rollout or a timeline for any of these features. That leaves multi-selection questions, product-listing refinements, and paginated answers as unconfirmed tests rather than permanent changes. Anyone relying on AI Mode for research or shopping should expect the interface to keep shifting without notice. Google AI Mode query expansion remains a moving target, and Schwartz’s report gives the clearest look at where it stands as of September 2026.
Watch for further posts from Sachin Patel or other searchers who spot new AI Mode layouts, since Google tends to test these features on a limited group before any wider release. Check whether your own searches show multi-selection prompts or refinement options next to product listings. Treat any changes you see as temporary until Google issues an official statement. As Google keeps testing new ways to refine AI Mode results, tools like Nuwtonic SEO can help you track how your content shows up across AI search surfaces so you’re not caught off guard by the next unannounced change.
