What the AI answer engines said when real buying questions were put to them, with no vendor named in the question.

“Answers” is how many of that category’s answers named this product. “Questions” is how many of its distinct buying questions named it at least once. Each category is asked twice from scratch and is only published if the top ten reproduces.
The page above is free and always will be. Two things are not: $9.99 a month to be told when this row moves — the rank, who took the mentions you were absent from, and which questions started or stopped naming you — and a $29.99 one-off report on why the engines name someone else, read out of the raw answers rather than guessed.
