Core Web Vitals are now crucial for SEO and user experience. Learn what they are, why they matter, and how to optimize them.
Largest Contentful Paint (LCP)
LCP measures loading performance. Optimize images, minimize CSS, defer non-critical JavaScript, and use content delivery networks (CDNs) to achieve LCP < 2.5s.
First Input Delay (FID)
FID measures interactivity. Reduce JavaScript execution time, break up long tasks, and optimize your JavaScript bundle for FID < 100ms.
Cumulative Layout Shift (CLS)
CLS measures visual stability. Reserve space for media, avoid inserting content above existing content, and use transform instead of properties that trigger layout.
Measurement Tools
Use Google PageSpeed Insights, Lighthouse, WebPageTest, and browser DevTools to measure and monitor your Core Web Vitals.
Optimization Strategies
Implement lazy loading, code splitting, caching strategies, and image optimization. Monitor metrics continuously and iterate.
