How this is measured

PromptRadar asks ChatGPT, Perplexity, Google AI and Claude real buying questions on behalf of the websites it tracks, then records which brands each answer named and which domains it cited. This page counts 2,975 answers from 241 scans, one scan per website, refreshed November 4, 2026.

Only aggregates are published. The questions themselves, the answer text, and the identity of the websites that ran a scan stay private. A domain appears here only when answers from at least 3 different websites cited it, and a brand enters a ranking only when answers from at least 2 different websites named it.
