AI visibility is how often, how early, and how favorably AI assistants like ChatGPT, Claude, Gemini, and Perplexity name a brand when people ask them for recommendations.
When a buyer asks an AI assistant "what's the best project management tool?", the assistant answers with a handful of brand names. Being one of those names — and being named early — is AI visibility. Brands that AI never names are invisible at the exact moment a buying decision is being shaped.
AI visibility is measurable. Ask the same questions to the same models on a schedule, record which brands each answer names and in what order, and you get a rank and a score per model per week — the same way a stock ticker turns trading into a price.
