Why Core Web Vitals Matter for SEO
Core Web Vitals are a set of metrics that measure real-world user experience for loading performance, interactivity, and visual stability of a page. They are part of Google's page experience signals and ranking factors. Good Core Web Vitals scores can improve your search rankings and provide a better user experience.
The three key metrics are: Largest Contentful Paint (LCP) which measures loading performance and should occur within 2.5 seconds, First Input Delay (FID) which measures interactivity and should be less than 100 milliseconds, and Cumulative Layout Shift (CLS) which measures visual stability and should be less than 0.1. To improve these metrics, optimize images and media, minimize JavaScript, use content delivery networks, implement lazy loading, and ensure proper sizing for media elements.
