The public dataset reports citation rates, rankings, and evidence counts. It excludes internal query identifiers, raw cited URLs, and answer-engine provider payloads. MRI measures observed root-domain citations in monitored prompts, not all AI answers, recommendation quality, web traffic or commercial performance. A citation is not source support.
AuthorityTech publication intelligence projection is a downstream practitioner projection. It is not source evidence, citation provenance, or sameAs identity for the neutral dataset.

Embed this profile’s badge
The link goes to this profile, the alt text is the citation above, and the badge is live: it always shows the current release, so it changes when the release changes and returns 404 if this domain leaves the released population. The embedder decides the link’s rel attribute. To keep a fixed image, download the SVG.
