Where do ChatGPT, Perplexity, and Google AI Overviews pull contractor information from?

Each engine draws from a different mix, which is why the same question returns different Tampa contractors in each tool. Perplexity runs a live web search and cites pages directly. Google AI Overviews leans on Google's own index plus Google Business Profile and Maps data. ChatGPT blends its training data with live browsing and Bing-style results. Microsoft Copilot pulls heavily from Bing, including Bing Places.

The practical takeaway is that you cannot optimize for one and ignore the rest. A crawlable website, a complete Google Business Profile, a claimed Bing Places listing, and consistent directory data cover all four at once.
