AIRANKS — The Authoritative Rankings for AI Web Content

AIRANKS measures AI visibility: we ask AI models real product and service questions, capture the complete answers as immutable observations, and publish what they contain — which brands were mentioned, which domains were cited, and which exact pages were linked. Every domain gets an AIR score from 1–10 (a decile of visibility in the active dataset; 0 means insufficient data), with the methodology in the open.

The Incomparability Lattice

what the intervals separate, not what the list claims

An edge means one brand's interval sits strictly above another's — zero overlap. No edge between two brands is not a gap in the drawing, it is the finding: their intervals overlap, and the bootstrap cannot tell them apart. Brands on the same rung are incomparable, not tied — the ranking above orders them anyway because a list has to print a total order; this diagram is the honest version.
