What is AI Share of Voice?

AI share of voice (AI SOV) is the percentage of AI-generated answers, for a defined set of queries, in which a brand is mentioned, cited or recommended — measured per engine (ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews) and tracked over time. It is the GEO equivalent of rank tracking in SEO.

In plain terms

AI Share of Voice, explained.

The measurement works by running the same buyer-relevant prompt set against each engine on a schedule, recording which brands and sources each answer includes, and computing your presence as a share of total answer opportunities.

Tracked weekly, AI SOV turns GEO from guesswork into a managed channel: you see exactly which engines and queries you're winning, where competitors displace you, and whether the work is moving the number.

Why it matters

It's the only reliable way to know whether AI engines recommend you at all.
Per-engine breakdowns reveal where to focus — engines index and cite differently.
A rising SOV curve is provable, reportable marketing ROI.

Common questions

Asked and answered.

How is AI SOV different from search rankings?

Rankings measure one engine's ordered list; AI SOV measures presence inside synthesized answers across multiple engines, where inclusion — not position — is the win condition.

How many queries should a tracking set include?

Enough to cover your revenue-relevant intents — typically 25–100 prompts spanning category, comparison, cost and local questions, kept stable so trends are meaningful.
