Prompt Visibility
Where you appear, rank and get cited for the prompts your buyers ask.
Site index for AI agents: /llms.txt. Documentation pages under /docs are also served as markdown at the same URL plus .md (e.g. /docs/geo-audit.md) or via an Accept: text/markdown request.
Track which of your URLs engines use as sources, where each sits in the citation list, and which gain ground.

A citation is the engine saying it trusted your page enough to build an answer on it. Most teams cannot tell a mention from a citation, because their analytics never sees either one.
The same article can be the first source on Perplexity, sixth in a Google AI Overview, and absent from ChatGPT. Reported per engine, that tells you which asset to strengthen.
A citation is not a visit. An engine can cite your page, answer the reader's question completely, and send nobody. Read this alongside AI Traffic.
Cited sources move more than brand mentions: in AirPulse's frozen study, consecutive cited-domain sets shared less than half their combined sources.
