Optimize Large Contentful Paint Element

High Impact+18 points estimated

Why It Matters

LCP is delayed by 9 seconds due to poor resource discovery and lack of priority hints on the banner element.

How to Fix

Add fetchpriority='high' to the banner section's background image or primary content. Use Next.js Image component with priority={true} for LCP images. Preload the banner's critical resources using next/head with <link rel='preload'> for fonts and images.

AI Performance Analysis

This Next.js/React website has poor performance with a score of 58/100. The biggest problem is an extremely slow Largest Contentful Paint of 9.0 seconds, primarily caused by render-blocking CSS files that delay page rendering by over 1 second. The site is also loading 468KB of unused JavaScript and 65KB of unused CSS, while images are oversized and poorly cached. Fixing the render-blocking resources, optimizing images, and removing unused code could improve the score by 30+ points and dramatically reduce load times from 14 seconds to under 4 seconds.

Other Optimization Recommendations

Eliminate Render-Blocking CSS Resources

High Impact+15 points estimated

Why It Matters:

CSS files are blocking initial render for over 1 second, severely delaying First Contentful Paint.

How to Fix:

Use Next.js dynamic imports for non-critical CSS modules. Implement critical CSS inlining in your _app.js for above-the-fold styles. Move remaining CSS to load asynchronously using next/dynamic with { ssr: false } for non-essential components.

Reduce Unused JavaScript Bundles

High Impact+12 points estimated

Why It Matters:

468KB of unused JavaScript is increasing Total Blocking Time and delaying interactivity.

How to Fix:

Implement code splitting in Next.js using dynamic imports for large components. Use next/bundle-analyzer to identify unused chunks. Remove or lazy-load the Google Analytics bundle and split the 2352 chunk into smaller, route-specific bundles using Next.js automatic code splitting.
