The public leaderboard of the world’s largest AI visibility index: more than 60 million companies tracked, more than 54 million scored 0 to 10 on how well ChatGPT, Claude, Gemini, and Perplexity can find, trust, and describe them. Rankings are pure score order among brands AI engines actually read; placement cannot be bought.
How the Index works: every company is scored by the same pipeline, six on-page signals plus off-page authority. In our published research, 78% of the brands ChatGPT recommended scored 6 or higher, versus 7% of a random sample of scored companies. Last refreshed 2026-09-20.
