Key Concepts or Points

Cumulative Layout Shift (CLS)
CLS tracks how much the layout shifts during page load, affecting the stability and visual experience of the page. Read more
Detailed Tips or Best Practices
1. Optimize LCP by Reducing Render-Blocking Resources
Ensure that critical CSS, JavaScript, and fonts load early to improve the speed at which content is visible.
2. Minimize FID with Efficient JavaScript
Break up long JavaScript tasks into smaller, async tasks to ensure fast interaction with the page.
3. Reduce CLS by Avoiding Layout Shifts
Reserve space for images and fonts during page load, and ensure dynamic content is positioned predictably.
4. Use Next.js Image Optimization
Leverage Next.js’s built-in image optimization features to serve the right image sizes for different devices and reduce LCP.
5. Implement Lazy Loading
Lazy load offscreen content such as images and videos to reduce initial page load time.
Conclusion
Optimizing Core Web Vitals enhances both user experience and SEO performance. Focus on LCP, FID, and CLS to improve your site’s ranking and usability.
