The AI Visibility Index
When somebody asks an AI assistant to recommend a marketing agency, most agencies are not returned at all. This is how often — measured across real audits, not estimated.
Across 725 audited sites, through September 2026.

Method
Each audit asks a language model the questions a buyer would actually ask — for a recommendation in a category and a place — and records whether the site is returned. “Invisible” means zero mentions across every question asked: not ranked poorly, absent. It is a claim any reader can check on their own domain in under a minute, which is why it is the number we publish.
