How this is measured
Each site's home page is tested with Google PageSpeed Insights (Lighthouse, simulated mid-range phone on a slow 4G connection) when it's enriched; real-user ratings come from the Chrome UX Report where Google has enough visits. Only sites in the Tranco top million are named. See also websites using HubSpot CMS. Updated October 2026.
