Limelit reports AI share of voice on every account, including the free one; it only counts the competitors you track, so the number is relative to that set.

## Definition

AI share of voice is the share of all brand mentions in AI answers, across a set of buyer questions, that go to one brand rather than to its competitors. In Limelit it is the Share of voice number: This brand's slice of all tracked-brand mentions (you plus your tracked competitors). It shows who dominates the conversation, and sums toward 100% across the tracked set. It is computed as (your mentions / mentions of you plus every tracked competitor) x 100.

(your mentions / mentions of you plus every tracked competitor) x 100

Questions

## The things people ask us first.

### How is AI share of voice different from AI visibility?

Visibility asks how often answers name you at all. Share of voice asks how the mentions split between you and the competitors you track, so it can fall while visibility rises if a competitor gains faster.

### Does AI share of voice add up to 100%?

Yes, across the tracked set. Your share plus every tracked competitor's share sums toward 100%, so adding a competitor to the set lowers everyone else's share.

### Which AI engines count toward share of voice in Limelit?

Every engine you run: ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews and Google AI Mode are on every account, with no engine paywall.

### Does a brand the prompt already names count as a mention?

No. A mention counts only when the brand string appears in the answer text, and a model echoing a brand the prompt named is filtered out as a likely hallucination.
