How this was measured.

Measured on 9 October 2026.
5 buyer questions, on ChatGPT, Claude, Perplexity, Gemini, Grok and AI Overview.
Asked more than once.
Each question went to each engine several times (Google AI Overview once), so the tables show rates, not one list.
Gaps stay gaps.
An answer that failed is left out of every count, never read as one that named nobody.
Every answer is here.
Quoted word for word, and in the CSV and JSON.
