Google's recent update to Core Web Vitals prioritizes user experience on websites, ranking search results accordingly. The three pillars of Core Web Vitals are speed, responsiveness, and visual stability, measured by Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) respectively. LCP measures perceived load speed, FID measures interactivity, and CLS measures visual stability. To improve these metrics, developers can optimize images, reduce JavaScript execution time, cache assets, avoid excessive DOM size, and adopt a Jamstack architecture on Netlify, which enables compression, minification, and caching by default, resulting in faster site delivery and better user experience.
