Share of Voice (AI)
A brand's mentions as a percentage of all brand mentions across the AI-generated answers to a set of tracked prompts.
How it works
If five brands get mentioned across the AI answers to a set of tracked prompts, and yours accounts for one out of every five mentions, your share of voice for that set is 20%. It's a relative measure — it moves when competitors gain or lose visibility, not just when your own mentions change.
Why it matters
A rising mention count can still mean a shrinking share of voice if competitors are growing faster. Tracking share of voice, not just raw mentions, is what shows whether a brand is actually winning or losing ground in AI-generated answers.
