How can I improve my site's Core Web Vitals scores?

Asked on Jan 05, 2026

Answer

Improving your site's Core Web Vitals scores involves optimizing three key metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics assess loading performance, interactivity, and visual stability, respectively.

Example Concept: Core Web Vitals are a set of user-centric metrics that Google uses to evaluate the quality of user experience on a webpage. Improving these scores typically involves optimizing server response times, enhancing resource loading efficiency, and minimizing layout shifts during page load.

Additional Comment:

Optimize images and use modern formats like WebP to improve LCP.
Implement lazy loading for offscreen images and iframes.
Minimize JavaScript execution to reduce FID.
Use CSS for animations instead of JavaScript to improve performance.
Ensure dimensions are set for all media to prevent CLS.
Utilize a Content Delivery Network (CDN) to speed up content delivery.
Regularly test your site using tools like Google PageSpeed Insights or Lighthouse.
