Is ChatGPT search the same as Google for SEO purposes?
No. ChatGPT search uses a different ranking model than Google. The biggest differences: ChatGPT weighs structured data and citable content (FAQPage, LocalBusiness, llms.txt) more heavily; backlinks matter less; freshness matters somewhat less. Sites that rank well on Google often need different (or additional) work to be cited by ChatGPT, especially in the small-business + local-services categories.
For small businesses, the easiest way to think about the difference is: Google asks "who is most authoritative on this topic?" while ChatGPT asks "who has the cleanest answer to this specific question?". The first rewards backlinks and authority; the second rewards structured Q&A content, plain HTML, and explicit signals like LocalBusiness JSON-LD.
In practice that means: a site that ranks #2 in Google for "best HVAC contractor in [city]" can still be invisible in ChatGPT if it doesn't ship FAQPage schema, doesn't have a /llms.txt, hides its services in an image carousel, or buries its certifications in a PDF. Conversely, a site that's nowhere on Google can land in ChatGPT if it has clean structured data and an HTML-readable services list.
The good news: most of the work that gets you cited by ChatGPT (structured data, plain HTML, FAQPage) ALSO helps your traditional Google ranking: Google has been rewarding structured data more aggressively since 2024 too. So the AEO work isn't separate from SEO; it's a sharper subset of it.

Common follow-ups
Should I stop doing traditional SEO?
No. Google still drives a large share of small-business search traffic in 2026. The right move is to do the AEO work (which mostly overlaps with structured-data SEO) and let the work compound across both engines.
