Share of voice FAQ

What is share of voice in AI search?

Share of voice is your brand’s mention count divided by total mentions of you plus named competitors in a set of AI answers. If you appear in 6 of 10 named mentions, you own 60% share of voice.

Where do I get mention counts?

Count how often each brand is named across a prompt set (for example 20 ChatGPT/Perplexity answers). BrandCitation’s paid scans compute this automatically across engines.

What if every count is zero?

The calculator reports that there is no share to compute. It will not invent percentages or divide by zero.

Is this the same as Google share of voice?

Same math, different inventory. Classic SEO share of voice uses ranked keywords. AI share of voice uses brand mentions inside generated answers — a smaller, winner-take-most list.

Is the calculator free?

Yes. Three free calculations, then an email gate. No credit card.
