A query fan-out is a technique used by ChatGPT where a single user prompt (query) is broken down by ChatGPT into multiple related sub-queries, then searched in parallel across OpenAI’s sources, and synthesized into one unified response.
ChatGPT’s sources include Google results (sourced from third-party providers, Google Business Profile reviews, OpenAI’s own index, and third party sites. For local personal injury attorney searches, review sites are important including Yelp, Acco, Martindale, Lawyers.com, Expertise, Super Lawyers, Justia, FindLaw and some other smaller directories.
Most Searches Do Not Get a Fanout:
It’s been repeated hundreds of thousands of times that all searches on ChatGPT result in a query fanout. This is incorrect. The vast majority of users use ChatGPT in “Fast” mode. Local searches in Fast mode get a query rewrite, not a query fanout.
For example, the ChatGPT search “best personal injury lawyer raleigh nc” results in a single query rewrite.
But, don’t take my word for it, here’s the evidence:
Query Fanouts VS Query Rewrites:
As you will see below, in Fast mode, most local / transactional search queries result in a rewrite.
Informational search queries do often result in a fanout, but the fanout may simply be two sub-queries, searched in parallel and synthesized into one unified response.
ChatGPT Query Fanout and Query Rewrite Examples (Fast Mode):
Below are real examples, performed November 7, 2026 in “Fast” mode. I did 3 “runs” of each query (3 searches) because each time you search ChatGPT it may come up with a completely new query fanout or rewrite.

How People Search ChatGPT:
A lot of people search hypothetical questions then turn to Google to hire.
In the event someone finds a firm on ChatGPT those individuals still often turn to Google to search for “Smith Law Firm Reviews”. Those users are likely to see Yelp reviews.
A high ranking site, with unique content and great reviews should be core to any GEO strategy.
