Distinct names
Each name appears only once: two rows with the same name, even with different capitalisation, are flagged.

What is your share of voice?
Enter the names to compare and how many times each one appears in the same set of answers or articles: the share is calculated in your browser.
How it’s calculated
One name’s mentions out of the total for those compared.
A name’s share of voice is its mentions divided by the sum of the mentions of all the names entered. The calculator rounds to whole points with the largest remainder method, so the total always comes to one hundred.
The three steps of the share of voice calculation: the mentions counted for each name, the sum of the counts as the total and the division rounded to whole points that together make one hundred.
You count the mentions
For each name, write how many times it appears in the chosen set.
The total is added up
The total is the sum of the mentions of all the names entered.
Divide and round
Each share is a whole point, and together the shares make one hundred.
The same set
A share only holds within the same set.
Mentions can be compared only if they come from the same set: the same questions or the same articles, the same period, the same rule on what counts as a mention. Otherwise the share measures the difference between the sources.
Three points on which two mention counts must match for the share of voice to be comparable: the starting set, the period observed and the rule that decides what counts as a mention.
| Misleading count | Comparable count | |
|---|---|---|
| Starting set | One brand counted in AI answers, the other in articles. | All names counted in the same answers or the same articles. |
| Period | Each name counted in different weeks, chosen case by case. | The same period for each name, from start to finish. |
| What counts | For one name products count too, for the other only the brand. | The same rule for all on names, products and variants. |
Calculation limits
The calculator does not count the mentions for you.
You bring the numbers: the tool does not search for answers, articles or posts and does not check the counts. A share says how much space a name takes compared with the others entered, not whether those mentions are favourable.
Whole numbers only
Mentions are counts from zero upwards; with a total of zero the share cannot be calculated.
Frequently asked questions
Questions about the share of voice calculator.
The answers clarify what share of voice means, why rounded shares always add up to one hundred and which names are worth entering for a meaningful comparison.
What does share of voice mean?
It is the share of mentions that belongs to one name out of the total mentions of the names compared. It is used to understand how much space a brand takes compared with its competitors within the same set.
Why do the shares always add up to one hundred?
The calculator rounds with the largest remainder method: it takes the whole part of each share and assigns the missing points to the names with the largest remainder. That way no point is lost in rounding.
Which names are worth entering?
Your brand and the competitors customers actually compare you with. Adding names that nobody compares lowers everyone’s shares without saying anything useful.
