What is Share of AI Voice?
Share of AI voice is the proportion of AI-generated answers — across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews — that cite or recommend your brand, relative to your competitors, for a defined set of queries. It is the AI-search analogue of traditional share of search or share of voice: instead of measuring ad impressions or organic rankings, it measures how often the AI names you when a user asks a buying-intent question like 'what's the best tool for X?'. It is tracked by running a fixed query set through each engine on a recurring schedule and recording who gets cited.
Why it matters for Reddit marketing
In an AI-mediated buying journey, the brands the assistant repeatedly names shape the shortlist before a human compares options. A rising share of AI voice is an early indicator of demand capture that traditional rank tracking misses entirely.
