How we count
We ask ChatGPT, Gemini, Perplexity and Google AI Overviews the questions people in the US actually search for (15 for this category), asked from the US, and read every answer: 56 answers here.
A brand scores when an answer recommends it. Its rank is the share of answers that named it. Shops, review sites and brands an answer warns against are not counted. Different spellings of the same brand are merged.
