Google defines query fan-out in its own optimization guide:
A set of concurrent, related queries generated by the model to request more information and fetch additional relevant search results to address the user's query.
Last verified: September 2, 2026.
Google's worked example starts with "how to fix a lawn that's full of weeds" and fans out into things like best herbicides for lawns and removing weeds without chemicals. A local service request behaves the same way: one question about a failed water heater turns into several searches about the job, the market, the proof, and who is available. Google does not publish the exact hidden set for any given answer.
The panel data does not separate the shapes Cheers can publish. Across the Cheers panel of 13 home-services companies, 28 days ending September 2, 2026, leaving out questions that name the company itself, aggregate only, broad "best or top" prompts without a place name returned a 28.4% pooled appearance rate and a 22.4% pooled citation rate. Prompts outside the named shapes returned 29.2% and 25.8%. Two shapes that close together do not support a ranking. "Best near me" and named-place prompts, price and cost, and how-and-why questions each sat behind fewer than ten companies, so Cheers does not publish a rate for them.

Cheers panel, 28 days ending September 2, 2026: 13 home-services companies, non-branded prompts, pooled citation rate by prompt shape. Citation means the company or its site appeared as a source. Aggregate only (corrected September 28, 2026).
| Prompt shape | Pooled citation rate |
|---|---|
| Prompts outside the named shapes | 25.8% (Appearance 29.2%) |
| Best or top lists, no place name | 22.4% (Appearance 28.4%) |
The case for writing pages that answer the whole buying decision, instead of chasing one phrase, rests on how Google describes fan-out, not on a gap between prompt shapes. The cuts are in AI visibility statistics and the sampling rules in the methodology.
What Google confirms
Google says AI Mode and AI Overviews use core Search ranking and quality systems. Retrieval-augmented generation pulls current pages from the Search index. Query fan-out generates related searches. The system then shows supporting links for the response.
That means the technical foundation still matters. A useful page has to be crawlable, indexed, eligible for a Search snippet, and linked clearly from the rest of the site. Google says there is no special AI schema or extra technical requirement.
What local operators should do
Write for the buying decision, not an imagined list of subqueries. A strong location page should state the services that branch truly provides, the area it serves, current contact and booking details, hours or availability, qualifications, and local proof.
The location-page checklist covers that structure. Service pages should answer the parts of the job that change the buyer's choice, such as what is included, who performs the work, how estimates work, and what evidence supports the claim.
Do not produce a thin page for every city-service wording. Google names the tactic and the policy directly, and then explains why it fails on its own terms:
a high quantity of pages doesn't make a website higher quality or more relevant to users
Creating separate content for every search variation or fan-out query, primarily to manipulate rankings or generative AI responses, violates Google's scaled content abuse spam policy. The safer version of that instinct is building city pages without doorway risk.

How I audit a result
I save the original prompt, AI Mode response, supporting links, market, and time checked. Then I compare the pages Google cited with the branch page and public business facts.
If a competitor page answers a real buyer concern more clearly, improve the useful content. If a source contains the wrong location or hours, correct the source. Do not claim to have reverse-engineered the hidden query tree from one response.
The AI engine source comparison explains why AI Mode should be tracked separately from ChatGPT, Perplexity, and Copilot. Does SEO Still Work? covers why the core Search work still matters. Use the AI Visibility Grader when you need a current baseline for your own business.
