Core Web Vitals measure real-world user experience on your website. They strongly influence both SEO and user satisfaction.
The Three Core Web Vitals
- LCP: Largest Contentful Paint – loading performance.
- INP/FID: Interaction to Next Paint – input responsiveness.
- CLS: Cumulative Layout Shift – visual stability.
Improving LCP
Optimize and lazy-load images, use fast hosting, and minimize render-blocking resources.
Improving Interactivity
Reduce heavy JavaScript, defer non-essential scripts, and simplify complex UI elements.
Improving CLS
Always reserve space for images and ads to prevent layout shifts as the page loads.
