Share of model is the AI-era analogue of share of voice. It is calculated against a defined set of high-intent prompts, the queries your buyers actually ask, and tracked per engine and over time. A 30% share of model means three in ten relevant AI answers include your brand; a 0% share means competitors are filling those answers without you.
