You measure AI visibility by tracking a fixed set of real, buyer-style questions across the major AI systems and recording whether your brand is mentioned, how accurately it is described, and which sources are cited. Because AI answers frequently produce no click, the core metric is presence and accuracy rather than traffic alone. A reliable method is to define the prompts that matter to your buyers, capture a baseline of how ChatGPT, Perplexity, Gemini, and Google’s AI Overviews answer them today, improve the underlying content and evidence, and then re-test on a regular schedule to see whether your share of the answer is rising. No one can guarantee placement in an AI answer — any provider promising guaranteed placement should be treated with caution — but the signals that earn citations can be built and monitored deliberately.
