Understanding Core Web Vitals
Google's Core Web Vitals are essential metrics that measure real-world user experience on your website. These three metrics are:
1. Largest Contentful Paint (LCP)
LCP measures the time it takes for the largest content element to become visible. Aim for 2.5 seconds or less.
2. First Input Delay (FID)
FID measures the responsiveness of your page to user interactions. Keep it below 100 milliseconds.
3. Cumulative Layout Shift (CLS)
CLS measures visual stability. Maintain a CLS score below 0.1 to avoid unexpected layout changes.
Optimization Techniques
Implement lazy loading, code splitting, image optimization, and caching strategies to improve these metrics significantly.
