Share of Answer

Share of Answer is the percentage of category-relevant prompts across major AI answer engines — ChatGPT, Perplexity, Gemini, Claude, Google AI Mode, and Grok — in which a brand is named, cited, or recommended. It is the generative-era equivalent of share of voice, measured against a fixed prompt panel run on a repeating cadence so month-over-month deltas are meaningful. Why it matters: Ranking on a keyword no longer guarantees inclusion in the answer a buyer actually sees. Share of Answer is the single clearest metric for whether reference-authority work — PR, entity clarity, citation building — is translating into visibility inside the AI responses that now mediate most high-intent research.
