This is the public reference the badge and the brand directory link to. It states what the score means, how it is measured, and the principles that keep the directory neutral.
AI visibility is how often a brand is mentioned and cited when people ask AI assistants questions within the brand's category, on a scale from 0 to 100. It always rests on real queries against the AI surfaces, never a model estimate.
We query several independent AI surfaces with real API calls: ChatGPT, Google Gemini, Anthropic Claude and Perplexity. No surface is simulated by another.
Paying buys no ranking advantage. The directory is ordered by category and name, never by score. Measured and unmeasured brands are split by data, not by payment.
