Why Core Web Vitals Matter

Core Web Vitals directly impact your search rankings, user experience, and ultimately your conversion rates. Google has made it clear: faster sites rank higher.

10 Techniques for Immediate Improvement

None of these 10 techniques require a rewrite. Applied incrementally, they typically move LCP and INP into the green within a single sprint.

1. Image Optimization

Use Next.js Image component with proper sizing, lazy loading, and WebP formats. This alone can reduce LCP by 50-70%.

2. Static Site Generation

Leverage static generation for as many pages as possible. Pre-rendering at build time eliminates server-side compute delays.

3. Edge Rendering

Edge rendering reduces latency by running your code closer to your users. Use Next.js Edge runtime for dynamic content that needs personalization.

  • Use strategic code splitting
  • Implement efficient caching strategies
  • Optimize third-party scripts
  • Reduce CSS and JavaScript bundle sizes
  • Use webp and modern formats
  • Implement responsive images
  • Preload critical resources
