How the rankings work
Each website's score (0–100) comes from Google's Chrome UX Report — what real Chrome users experienced over a roughly 28-day window. It weights five field metrics at the 75th percentile: Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint, First Contentful Paint and Time to First Byte. Above 80 is good, 61–80 needs improvement, 60 or less is poor.
It measures website performance, not a dealership's sales or service. Active dealership websites with enough Chrome traffic to be measured are ranked; the rest aren't scored rather than scored low.
