How we measured this

We asked 10 questions a customer might ask about plumbers in Mesa, AZ, once on each AI tool, through each tool's official API. For example:

  • I need an emergency plumber in Mesa, AZ right now. Who should I call?
  • Who is the most trusted plumber in Mesa, AZ?
  • Which plumbing company in Mesa, AZ is best for water heater repair?

Perplexity searches the web and shows its sources. Gemini (model knowledge) answers without a web search, from what the model learned in training, so its picks can be out of date. A language model read each answer and listed the businesses it named, and a business counts once per answer. These results describe what AI said on these dates. They are not a rating of any business's work.
