Good performance on Core Web Vitals leads to better rankings on Google, as user experience directly impacts SEO.

Key Concepts or Points

Largest Contentful Paint (LCP)

LCP measures how quickly the largest visible content element (like an image or text block) loads on the screen. Read more

First Input Delay (FID)

FID measures the time it takes for the page to respond to a user’s first interaction (click, tap, etc.). Read more

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.
