How do I improve my site's Core Web Vitals scores?
Asked on Oct 24, 2025
Answer
Improving your site's Core Web Vitals scores involves optimizing for three main metrics: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Each metric addresses a different aspect of user experience, focusing on loading performance, interactivity, and visual stability.
Example Concept: Core Web Vitals are a set of metrics defined by Google to quantify key aspects of user experience on the web. LCP measures loading performance, FID assesses interactivity, and CLS evaluates visual stability. Improving these scores involves optimizing server response times, reducing JavaScript execution, and ensuring elements are properly sized and positioned to prevent unexpected layout shifts.
Additional Comment:
- Optimize images and use modern formats like WebP to improve LCP.
- Minimize JavaScript and defer non-essential scripts to enhance FID.
- Use CSS to reserve space for images and ads to reduce CLS.
- Leverage browser caching and content delivery networks (CDNs) for faster resource loading.
- Regularly monitor your site's performance using tools like Google PageSpeed Insights and Lighthouse.
