AI referral attribution
Measuring the visits that arrived from an AI answer, the traffic-side complement to share of voice. It is weaker than it looks. Referrer granularity varies by engine, some send none, and agentic browsers send a browser's. A visit proves a person followed a link once; it is not evidence that the page influenced any future answer, and a page cited often with no click-through is invisible to it entirely. Useful as a trend on one site; not comparable across engines or sites.
