SearchestraOf Every 10 Times AI Names a Brand in Your Category, How Many Are You?
Your mention rate went up, so things are good, right? Not necessarily. If your competitors rose faster, you are losing ground while your own number climbs. Share of voice answers the question your CEO actually asks: of all the times AI names a brand in our category, how often is it us?
Rising and losing at the same time
Absolute mention rate can climb while your slice of the category shrinks, because a competitor is climbing faster. Share of voice reframes the number as a share of the whole, which is the only version that tells you whether you are winning the category or quietly being displaced.
The number only means something if the set is disclosed
| Choice | Why it changes your share |
|---|---|
| Which competitors are in the set | They are your denominator |
| How the category is sized | Changes the whole you are a share of |
| Whether the set is disclosed | Undisclosed means not comparable |
A share-of-voice figure with a hidden competitive set is not comparable to anyone else's, and not defensible to your board.
See your slice, and who is taking it
Searchestra builds share of voice on a competitive set you can review and edit, and shows your position on a leaderboard, so the relative picture, and who is displacing you, is explicit and defensible.
A rising mention rate can still mean losing the category; measure share of voice against a disclosed competitive set to see your real slice.
Frequently asked questions
How is share of voice different from mention rate?
Mention rate is your absolute frequency; share of voice is that as a proportion of all brand mentions in a defined category set.
Can my mention rate rise while I lose share?
Yes. If competitors rise faster, your slice of the category shrinks even as your own number climbs.
Why must the competitive set be disclosed?
Because it is the denominator. Change it and your share changes without your visibility changing at all.
