LLM Visibility
How often your brand or website is cited in AI system responses.
Full definition
LLM Visibility is a metric measuring how often and in what tone your brand, product, or expertise is mentioned in responses from large language models (ChatGPT, Claude, Gemini, Perplexity).
This is a new dimension of digital presence: a site can rank #1 in Google yet have zero LLM visibility — and vice versa.
How to measure: manual monitoring (a list of 20–30 target questions + monthly checks across several models), or automated tools (Profound, Otterly.AI, BrandMentions AI).
What drives it: volume of expert content, mentions in authoritative publications, presence in Wikidata/Wikipedia, reviews on Trustpilot/G2, Schema.org markup.
