# Share of Model Voice (SOMV)

> What Share of Model Voice (SOMV) measures: how often a brand is mentioned by ChatGPT, Perplexity and Claude — the new visibility metric, explained.

Synonyms: SOMV, AI share of voice, AI answer visibility

Classic SEO metrics such as ranking position or visibility index assume a results list a user clicks through. With generative AI answers, that list is often gone — there's just a single, summarised answer. Share of Model Voice carries the underlying idea of visibility over into this new reality: how often does a brand appear in the answers of leading AI systems when users ask typical industry questions — and in what tone, in what position, in comparison to which competitors?

SOMV is measured by regularly putting recurring customer questions to ChatGPT, Perplexity, Claude and comparable systems, and logging whether, how often, and how correctly your own business is mentioned. For businesses, this figure is increasingly becoming the real visibility metric — regardless of whether it still results in a classic website click.
