What Is Share of Model?
Share of Model is an audit-derived estimate of how often your brand is recommended or cited by AI systems for your target prompts, relative to tracked competitors.
It is the recommendation-layer equivalent of share of search.
Simple formula
Share of Model = Brand Mentions / Total Mentions (you + competitors)
