How a Los Angeles ranking is made

  1. 1We askThe same questions real customers ask — “Who's the best plumber in Tampa?” — go to 12 AI assistants, including ChatGPT, Google's AI, Claude and Gemini.
  2. 2They answerEach assistant names the businesses it recommends. We record every answer and check each name is a real business.
  3. 3We rankThe more assistants that name a business, and the more often, the higher it ranks. It updates every month, and nobody can pay to be on it.

ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Microsoft Copilot search the web as they answer; Grok, Meta AI, DeepSeek, Mistral answer from what they learned in training, and Siri and Alexa through their voice assistants. Each is labeled in the methodology.

Rankings summarize what the AI assistants answered on a fixed, unbranded question set — they are measurements of AI output, not AI Syndicate's endorsement of any business. Placement cannot be bought. Full detail in the methodology.
