Remove Unused JavaScript Code Splitting
High Impact+15 points estimated
Why It Matters
281 KiB of unused JavaScript is increasing bundle size and delaying LCP by 900ms.
How to Fix
Use Next.js dynamic imports with React.lazy() for components not needed on initial load. Configure webpack-bundle-analyzer to identify unused code. Remove or defer Google Tag Manager and analytics scripts using next/script with strategy='afterInteractive'.

AI Performance Analysis
This Next.js site has poor performance with a score of 52/100, indicating significant user experience issues. The biggest problem is an extremely slow Time to Interactive of 11 seconds, primarily caused by excessive JavaScript execution (4+ seconds) from oversized bundles that contain 281 KiB of unused code and outdated polyfills. The site is also suffering from render-blocking CSS files and forced reflows that delay content painting, resulting in a sluggish 6.2-second Largest Contentful Paint. Removing unused JavaScript, updating the build configuration to eliminate unnecessary polyfills, and optimizing CSS delivery could dramatically improve performance and reduce loading times by several seconds.
Other Optimization Recommendations
Eliminate Render Blocking CSS Resources
High Impact+18 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying LCP by 600ms, preventing users from seeing content quickly.
How to Fix:
In your Next.js app, move critical CSS inline using next/head for above-the-fold styles. Use dynamic imports for non-critical CSS chunks. Configure next.config.js to enable CSS optimization with experimental.optimizeCss: true.
Upgrade JavaScript Build Target Configuration
Medium Impact+8 points estimatedWhy It Matters:
Legacy JavaScript polyfills add 40 KiB of unnecessary code that modern browsers don't need.
How to Fix:
Update your Next.js config to target modern browsers by setting target: 'es2020' in next.config.js. Configure Babel to exclude unnecessary polyfills for Array.prototype.at, Object.hasOwn, and other modern features. Use browserslist to define your supported browser versions.
