An AI Visibility Score is a 0–100 measure of how prominently a single AI model recommends a brand in a category, based on whether the brand is mentioned, how early it appears, and how consistently it shows up across queries.
A score of 100 means the model names the brand first, essentially every time the category question is asked. A score of 0 means the model never names it. Everything in between reflects the share and prominence of the brand across the period's recorded answers.
Scores are computed per model, so a brand carries four scores — one each for ChatGPT, Claude, Gemini, and Perplexity — plus a consensus score that blends them. The gap between a brand's best and worst model score is its spread, and a wide spread is a finding in itself: the models disagree about you.
