# Mention Rate

**Mention rate** is the foundational metric for understanding an LLM's perception of a brand and the first pillar of the [[framework-three-prong-ai-perception|Three-Prong Lens]] that underpins [[concept-share-of-model-d10|Share of Model]]. It tracks the raw frequency with which a specific brand is explicitly named by a specific LLM when queried about a category or use case.

Because LLMs act as **gatekeepers** — either featuring a brand or omitting it entirely — mention rate is effectively a **binary indicator of existence within the AI's 'consciousness.'** Unlike traditional search, where a brand might simply rank lower on 'page two,' a **zero mention rate on an LLM means total invisibility** to the consumer (see [[claim-no-page-two-in-llms]] and [[quote-no-page-two]]).

**Enrichment:** External SOM frameworks corroborate this as the core input. Agile Brand Guide defines the base ratio as (mentions of your brand ÷ total brand mentions in responses) × 100; TrySteakhouse's equivalent 'citation probability' is (Total Mentions / Total Runs) × 100; Marketing Week's SOM coverage centers on tracking mention rate over time. Because generation is stochastic, a reliable mention rate must be derived from **many prompts and regenerations**, not a single query.
