Sources and method

For each technology the pass rate is the report's good_number divided by tested for the 'overall' Core Web Vitals assessment on mobile in the 2026-09-01 release (the latest available), worldwide and all site ranks, shown to one decimal place. 'Origins assessed' is the tested count.

A site passes when LCP, INP and CLS are all good at the 75th percentile of real Chrome users. Samples are small for Salesforce Commerce Cloud and GoDaddy Website Builder. Platform detection is by Wappalyzer, so a WooCommerce store is also counted under WordPress.
