Share of Voice (AI)
Also known as: AI SOV
AI share of voice is the percentage of relevant AI answers that mention your brand, measured against your competitors. If ten buyer prompts return answers and you appear in four, your share of voice is 40 percent. It turns raw mentions into a competitive standing you can track over time.
AI share of voice answers a competitive question: of all the AI answers where a brand in your category could be mentioned, how many mention you? It reframes AI visibility as a contest. A raw count of mentions tells you that you were named; share of voice tells you whether you are winning or losing against the brands you actually compete with.
How it is measured
Fix a representative set of buyer-intent prompts, run each across the engines your buyers use, and count how many answers name you against the total set. There are two common flavors:
- Presence-based: any mention counts equally. Simple and stable.
- Weighted: a first or explicitly recommended mention scores higher than a passing one, so prominence is rewarded.
Because engines disagree, share of voice is tracked per engine and then rolled up, not averaged into a single misleading number.
Why it is the metric that sticks
Executives understand share. “We appear in 20 percent of AI answers and our main rival appears in 55 percent” is a sentence that drives action, where “we got 43 mentions” is not. Tracked over time, share of voice shows whether your GEO work is closing the gap. For the full breakdown, see AI share of voice explained.
Frequently asked questions
How is AI share of voice calculated?
Take a fixed set of buyer prompts, run them across each engine, and count the answers that mention your brand versus the total. Presence-based share of voice counts any mention; weighted versions give more credit for being named first or recommended.
What is a good AI share of voice?
There is no universal number. What matters is your share relative to direct competitors on the prompts that drive decisions, and whether that share is rising. Being the leader on ten buyer-intent prompts beats a high average across trivial ones.
Why track share of voice instead of just mentions?
A raw mention count has no context. Share of voice compares you to competitors on the same prompts, so it tells you whether you are winning or losing the category, not just whether you were named.
