How does ChatGPT find businesses to name?
When a question needs current information, ChatGPT searches the web, reads what comes back and writes an answer with links to some of its sources. OpenAI says ChatGPT "typically rewrites your query into one or more targeted queries" and sends them to search providers. For local questions, it can use an approximate location based on the user's IP address.
OpenAI's own example: someone in the San Francisco area who asks "What are some good restaurants near me?" may get a search for "top restaurants San Francisco." After the first results, ChatGPT "may send additional, more specific queries." So a homeowner's question like "who should I call about a leaking water heater?" can turn into several searches you never see. That process is often called query fan-out.
We've seen it in our own research. In a separate, smaller check from our 50-metro study, we asked ChatGPT with web search, five times, "Who is a good marketing agency for a HVAC company?" The runs were collected around October 21, 2026 through a third-party data provider, not through the OpenAI API we use for our study. The searches the provider recorded included "best HVAC marketing agencies for contractors services 2026" and "HVAC lead generation services agencies pricing reviews." Treat them as examples of what one tool did on those days, not as a measurement.
Three details matter for an owner:
- Reading isn't citing. OpenAI's developer documentation says the full list of pages consulted "is often greater than the number of citations." Your page can be read and not linked.
- Named isn't the same as cited. An answer can name your company without linking your site, or link your page without naming you. Our glossary entry on AI citations covers the difference.
- Not every answer searches. OpenAI says ChatGPT "may search the web automatically when your question would benefit from current information." Without a search, the answer comes from what the model already learned, which you can't edit directly.
