Assistants sample their output, so the same question gives different results on different runs. We ask each prompt repeatedly on every engine and show you how often you are actually named.
The share of answers that mention you at all. The blunt measure, and the one that moves first when third-party coverage changes.
The share that present you as a suggested option rather than listing you in passing. This is the number that tracks revenue most closely.
Whether what the assistant says about your pricing, features and positioning is currently true. A confident wrong answer costs you the sale as surely as no answer.
