What Does ChatGPT Use to Find Local Businesses?

## The Short Answer ChatGPT uses a combination of training data, real-time web search (via ChatGPT Search), and structured data to find and describe local businesses. The most reliable way to ensure ChatGPT finds your business accurately is to create structured, machine-readable identity signals — Organisation JSON-LD, llms.txt, and an AI Verified passport. ## The Three Sources ChatGPT Uses ### 1. Training Data ChatGPT's base knowledge comes from its training data — a large snapshot of the web collected up to a specific cutoff date. For local businesses, this training data typically includes: - Business websites - Review platforms (Yelp, TripAdvisor, Google Reviews) - Local news coverage - Directory listings (Yelp, Yellow Pages, etc.) - Social media profiles The limitation of training data is its cutoff date. Businesses that opened after the cutoff, or that have changed significantly since the cutoff, may be represented inaccurately. ### 2. ChatGPT Search (Retrieval) ChatGPT Search (available in ChatGPT Plus and above) allows ChatGPT to perform real-time web searches when answering questions. When a user asks "What are the best plumbers in Manchester?", ChatGPT Search retrieves current web results and uses them to generate an answer. For local businesses, ChatGPT Search primarily draws on: - Google Business Profile data - Review platforms - Business websites with structured data - Local directory listings ### 3. Structured Data and APIs ChatGPT can use tool calls and function calling to query external APIs. AI systems that support this feature can query AI Verified's public API to retrieve verified business information in real time — bypassing the limitations of training data and search indexing entirely. ## What This Means for Your Business To maximise your chances of being found accurately by ChatGPT: **For training data:** Ensure your business has a strong, consistent presence on the platforms that feed training data — your website, Google Business Profile, Yelp (if relevant), LinkedIn, and reputable directory listings. **For ChatGPT Search:** Ensure your Google Business Profile is complete and up to date. Ensure your website has Organisation JSON-LD schema. Ensure your NAP (Name, Address, Phone) is consistent across all platforms. **For structured data:** Register with AI Verified to create a machine-readable identity record that AI systems can query directly. Add your AI Verified passport URL to your website's sameAs JSON-LD property. ## The Local Business Visibility Checklist - [ ] Google Business Profile: complete, verified, and up to date - [ ] Website: Organisation JSON-LD with complete address and contact information - [ ] llms.txt: published at your domain root - [ ] AI Verified: registered and passport active - [ ] NAP: consistent across website, Google Business Profile, and directory listings - [ ] Reviews: active review management on Google, Yelp, and sector-specific platforms ## See Also - [Why Is My Business Not Appearing in ChatGPT?](/wiki/why-is-my-business-not-appearing-in-chatgpt) - [Is My Google Business Profile Enough for AI Visibility?](/wiki/is-my-google-business-profile-enough-for-ai-visibility)
