The AI Visibility Index
Short answer
The AI Visibility Index is Vizaeo's public record of how businesses appear in answers from ChatGPT, Claude, Gemini, and Perplexity. Each dataset samples real answers to buyer-intent questions, tallies which businesses are named, and publishes the findings with the method attached. No positions are sold and no rankings are promised. The index simply shows what the assistants said.
How the index works
- Questions are the ones real buyers ask an assistant, in plain words, by business type and place.
- Each question is asked repeatedly, because a single AI answer varies from run to run and proves nothing.
- Mentions are tallied per business, and the tally method is checked against human-labelled answers.
- Every dataset is date-stamped and published with its study design, so anyone can re-run it and compare.
Datasets
More datasets are added as they are measured. If your business type is not here yet, the checker on the home page runs the same measurement for your firm alone, free.
The standard behind the numbers
Every term used in an Index dataset (mention rate, recommendation rate, citation rate, share of voice) is defined once, in Metrics and Method: The AI Visibility Standard, along with the full measurement method. The index and the standard are published so the numbers can be argued with, checked, and re-run by anyone.
