How is this measured?
Every month we ask ChatGPT, Claude, Gemini, and Perplexity a frozen panel of 50 real buyer questions about mattresses, each phrased three ways and repeated three times. We detect which brands each answer mentions and explicitly recommends, then score every brand 0–100 with statistical confidence intervals. Nothing on this page is sponsored, and paying never affects a score.
Know when AI changes its mind
One digest email per cycle, only when something statistically real happens — a new consensus pick, a brand the AIs stopped recommending.
Scores are 0–100 visibility scores with bootstrap 95% confidence intervals; mention and recommendation rates are averaged across the four core assistants. helloranked accepts no payment for placement — see the full methodology. Raw data is open (CC BY 4.0) on the data page.
