# AIRANKS — The Authoritative Rankings for AI Web Content (full)

> AIRANKS measures AI visibility. We ask the Machine real product and service questions
> ("what is the best espresso machine"), capture the complete answers as immutable
> observations, and publish what they contain: which brands were mentioned, which domains
> were cited, which exact pages were linked. Scores are 1–10 deciles of visibility within
> the active dataset; 0 means insufficient data, never "bad". Counts are cumulative
> observations, not rates.

## What we measure

Every observation is a stored, replayable record of one answer to one phrase at one moment:
the phrase asked, the full answer, every brand the answer ranked, and every citation the
answer carried (host and canonical URL, with advertising click-ids flagged when present).
From those observations we derive:

- **Phrase rankings** — which brands an answer ranks for a given question, with stability
  measured across resamples rather than asserted from a single run.
- **Brand visibility** — how often a brand appears across all answers in the dataset.
- **Domain citations** — which sites answers cite as sources, at host and page granularity,
  including the share of citations that arrive through advertising-tagged links.
- **AIR score** — a 1–10 decile of visibility. Gates apply before anything is scored:
  domains need 3+ occurrences, brands 5+ mentions, phrases 25+ observations.

## What we deliberately do not claim

- We do not claim to know why the Machine answers as it does — only what it answered.
- A window is not a rate: a good day is reported as a day, never multiplied into a trend.
- Datasets are never pooled across measurement conditions; each dataset is its own axis.
- A mismatch with any public chat app is not an error: we measure the model's API surface,
  and the app may source its answers differently.
