Share of voice (AI)

AI share of voice is a brand's citation or mention rate expressed as a proportion of the total across a defined competitive set, for a given prompt set, surface and market.

Share of voice is only meaningful when the competitive set is declared. Adding or removing one competitor changes every number in the report.

Like citation share, it should carry an interval, since it is derived from sampled rates.
