AI Share of Voice
AI share of voice is the proportion of tracked prompts in which a business is mentioned, relative to its competitors, across AI engines.
It reframes visibility as competitive rather than absolute. Being mentioned in 30% of prompts means little until you know the leading competitor is mentioned in 80%.
Measured per engine it becomes more useful still, because engines diverge sharply — a business can lead on Perplexity and be absent from Gemini, which points directly at what to fix.
Why it matters
It converts a vague sense of AI visibility into a number that can be tracked and compared, and it identifies which competitor is taking the answers you want.
