How to Measure AI Entity Authority

AI entity authority measurement involves three categories of evidence: AI citation presence (does the entity appear in AI-generated responses for target queries?), citation frequency (how often does the entity appear per 100 relevant queries?), and citation quality (is the entity cited as a primary source or a peripheral mention?).

Operators measure entity authority using a standardized query testing protocol: run 20–50 target queries through ChatGPT, Perplexity, and Google AI Overviews; record citation presence, position, and context; compare against baseline from pre-build audit. The delta between baseline and current state is the measurable impact of the GII build.

An operator conducts a 90-day post-build audit for a Seattle pediatric dentist: pre-build baseline showed 0 citations in 40 test queries; post-build measurement shows 12 citations in the same 40 queries. The operator reports this as a 30% citation rate against target queries in the client deliverable.
