AI visibility metrics, defined once
The AI visibility metrics and SEO metrics Quattr measures, every one of them: what it means, how it's calculated, which sources feed it, which skills use it, which reports you meet it in, and what it is not to be confused with. Written for the analyst who needs the formula and the newcomer who needs the sentence.
These are the measurements Quattr's MCP answers with inside Claude, ChatGPT and Cursor, watch one get answered if you'd rather see it than read it.

Verified: the formula and sources were confirmed against the product by the analytics owner (Saket Mittal, September 2026). Inferred: the definition follows the product's documentation and has not yet been confirmed against the implementation. In review: drafted, awaiting the analytics owner's sign-off, shown so the gap is visible rather than hidden.
