CVR-14 (14-Day Conversion Velocity)

CVR-14 measures how often shoppers who land on your product page actually buy, averaged across the last 14 days. The 14-day window is wide enough to smooth out daily noise but narrow enough to reflect recent listing performance. Amazon's A10 algorithm normalizes each listing's CVR-14 against its subcategory median, so a 6% CVR in a category where the median is 4% scores higher than a 9% CVR in a category where the median is 10%. The May 2026 algorithm rewrite up-weighted CVR-14 substantially. As a practical consequence, a keyword in your title that earns impressions but converts poorly now actively hurts your organic rank, because it drags your CVR-14 down.
