AI share of voice is the percentage of relevant AI answers that mention your brand compared with competitors. If assistants answer 20 key questions and name you in 5 while a competitor appears in 12, your share is lower, and the gap shows where to focus.

How it is calculated
Choose a fixed set of customer questions, run them across chosen assistants, record every brand named, then divide your mentions by total brand mentions. Repeat monthly with the same set.
Reading the number
| Pattern | Likely meaning |
|---|---|
| Low share, accurate description | Visibility problem: not enough evidence or reach |
| Decent share, wrong description | Accuracy problem: conflicting information |
| Share varies by assistant | Different sources favored by different tools |
Our expert view
Share of voice is most useful when tied to specific questions. A low share on "best emergency plumber" matters more than on a trivia question nobody buys from.

Frequently asked questions
How many questions should I track?
Enough to represent real buying questions; often 20 to 50.
Are results stable?
Assistants vary answers, so we look at trends over months.
Can I compare across countries?
Yes, by running questions with location context.
Limits and honest expectations
Search engines and AI assistants change their answers over time and no one controls them. Results vary by industry, city and competition, and we do not guarantee a position, a mention or a number of leads. We report what is measurable, plainly.
