The short answer
When someone asks ChatGPT or Claude for the best gym in a Sydney suburb, the assistants read Yelp and ClassPass first (Yelp was read in half of all gym answers, every one of them by Claude, and ClassPass in 36%) and name only a few businesses: ChatGPT 3.2 per answer, Claude 7.3. If you are on the pages they read, with your suburb and services in words, you can be one of them.
How we measured it: between 27 October 2026 and 29 October 2026 we asked OpenAI’s and Anthropic’s own models (the ones behind ChatGPT and Claude), with web search on, for the best gym in 25 suburb areas in Sydney (as of 29 October 2026), six answers each, and recorded every website the assistants read.
Four steps
- Be on Yelp and ClassPass, complete. Services, suburb, hours and a plain description. Yelp was read in half of all gym answers, every one of them by Claude, and ClassPass in 36%.
- Cover both assistants. Claude read Yelp in most of its answers, so a complete Yelp listing gives Claude a place to find you. ChatGPT reads Reddit threads where locals recommend businesses. You can’t list yourself there, and posting fake recommendations breaks Reddit’s rules. What helps is real customers mentioning you.
- Match your details everywhere. The same name, address and phone on Google, your website and each listing. The assistants match businesses by these.
- Check your suburb, then re-check. 13 different gyms typically came up across the six answers for one suburb, and the names move. The free check shows where you stand today.
None of this guarantees a recommendation. The assistants decide, and their answers change from day to day. These steps make you easier to find and to describe, which is the part you control.

Real examples from our answers
These are businesses the assistants recommended in our October check, shown with their real counts: Hiscoes Gym in Surry Hills was recommended in 6 of 6 answers; Flow Athletic in Paddington in 6 of 6. We name a business only where it was recommended, and never for health trades.
