Share of Voice

Share of voice is the proportion of all business mentions across a set of AI answers that belong to one business, measured against the competitors named in the same answers. Where a mention rate asks how often you appear, share of voice asks how much of the room you take up when the question is asked.

How it is computed

Take a panel of questions for one trade in one place, put each to an assistant, and count every business named across all the answers. A business’s share is its own mentions over that total. Weighting is optional: a first-position recommendation can count for more than a name in a list, though this site’s score does not weight it and reports being named first beside the score instead. Because the panel is asked again on the same questions, once the fixes are live and every month with monitoring, the share moves only when the answers move, and the answers are kept verbatim so a change can be traced to the sentence that caused it. The panel is described on the methodology page.

Share of voice and the visibility score

The score is about one business: the share of a fixed panel of answers that named it, on a 0 to 100 scale. Share of voice is relative. You can hold a steady score while a new competitor takes share, or gain share when a competitor drops out of the answers without changing a word on your own site. The two are read together: the score says whether the assistant knows you; the share says who else it knows and how the attention divides.

A common question

Is share of voice the same as market share?

No. Market share is a share of customers or revenue. Share of voice is a share of the names an assistant gives when asked, and it says nothing about who was then hired. The one leads to the other only if being named leads to being chosen, which this measurement does not claim to show.
