CWV

Meaning

CWV stands for Core Web Vitals: a set of measurements describing the loading speed, responsiveness and visual stability of real page visits. They are Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift. Google's guidance treats the good range as LCP within 2.5 seconds, INP of 200 milliseconds or less and CLS of 0.1 or less, measured at the 75th percentile of visits. You can check them in Search Console and PageSpeed Insights. See also: Technical SEO, CDN, and the guide Technical SEO Basics: Speed, Mobile, Crawling and Security.
