Short answer: ChatGPT recommends local businesses mostly from live web search results, so it can only suggest you if its crawler can reach your site and other sources agree on who you are. Keep your Business Profile, website and directory listings consistent, earn reviews on more than one platform, and publish clear pages that answer customers' questions.
ChatGPT, Gemini, Perplexity and Copilot now answer questions like "best plumber in Houston" with named businesses. None of them publishes a ranking formula, so this guide sticks to how they retrieve information and what you can control. It is the approach behind our AI search optimization for local businesses.

How AI assistants choose recommendations
- Live search, then summarise. For local questions the assistants run a web search, read the results and write an answer. ChatGPT search uses its own crawler (OAI-SearchBot) and partner search data; Copilot uses Bing; Gemini uses Google's index and Maps data.
- Agreement across sources. Your website, Business Profile, Bing Places, Apple Business (formerly Apple Business Connect) and directories should say the same thing.
- Third-party evidence. Reviews, local press, association listings and "best of" lists give the assistant something to cite.
- Clear pages. Direct question-and-answer content is easier to quote. Structured data may help machines read it; no assistant has confirmed how much it counts.
How to optimize for AI recommendations
Step 1: allow OAI-SearchBot, Bingbot and Googlebot in robots.txt and check your host's firewall does not block them. Step 2: make name, address, phone, services and service area identical everywhere, including Apple Business and Bing Places. Step 3: publish pages that answer the questions customers ask, answer first. Step 4: use specific facts you can stand behind, never invented numbers. Step 5: earn reviews and real mentions on other sites. An llms.txt file is optional: it is cheap to add, but no major assistant has confirmed it uses one. If you want this done for you, see our AI search optimization service.
How to check whether ChatGPT recommends you
Write 10 to 20 questions a customer would ask, such as "who fixes [service] in [city]". Once a month, ask each one in ChatGPT, Gemini, Perplexity and Copilot, logged out where possible, and record whether you are named and which sources are cited. Those cited sources are where to get listed or mentioned next. In analytics, ChatGPT referrals usually arrive with utm_source=chatgpt.com.
Patterns that fail with AI
Vague marketing language ("we're the best"). Different business names on different platforms. Blocking AI crawlers by accident. Thin pages with no specific information. Outdated hours or services anywhere on the web.
Updated October 9, 2026: corrected how assistants retrieve local answers (live search, named crawlers), marked llms.txt as optional and unconfirmed, removed fixed timelines and added a monthly check method. Sources: Google Search Central: AI features and your website.
