When someone asks ChatGPT which plumber to call in their city, two different things can happen: the answer names a business, or it cites a web page as a source. Those are separate mechanisms, and for a local service business the named business is the one that drives phone calls. Both rest on the same foundation: an accurate Google Business Profile, one name/address/phone everywhere, structured data that identifies your business precisely, pages that answer real questions with real numbers and dates, and mentions on third-party sites the answer engines already pull from. This guide covers how those pieces work, what Google and OpenAI actually document, and how to verify progress without buying a tool.
