Remove Unused CSS and JavaScript
High Impact+12 points estimated
Why It Matters
29KB of unused CSS and 282KB of unused JavaScript are unnecessarily increasing bundle size and blocking the main thread for 1.1 seconds.
How to Fix
Enable tree shaking in Next.js webpack config and use dynamic imports for large components. Run npm install --save-dev @next/bundle-analyzer to identify bloated chunks. Remove unused polyfills by updating your browserslist to exclude legacy browser support if not needed.

What This Score Means
A score of 92 falls in the "Good" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This Next.js site has excellent performance with a score of 92/100, but there are still some optimization opportunities. The biggest issue is render-blocking CSS files that are delaying your page's initial render by about 590ms, which impacts both First Contentful Paint and Largest Contentful Paint. You could see immediate improvements by deferring or inlining the CSS, and removing 282 KiB of unused JavaScript would further enhance loading speed. Additionally, the site is loading legacy JavaScript polyfills that aren't needed for modern browsers, wasting 40 KiB that could be eliminated by updating your build process.
Other Optimization Recommendations
Eliminate Render Blocking CSS Resources
High Impact+15 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying LCP/FCP by 590ms, preventing users from seeing content quickly.
How to Fix:
Inline critical CSS for above-the-fold content in Next.js using styled-jsx or CSS-in-JS libraries. Use next/dynamic with ssr: false for non-critical components. Split large CSS files and load non-critical styles asynchronously using media='print' onload='this.media="all"' technique.
Fix Forced Reflow Performance Issues
Medium Impact+8 points estimatedWhy It Matters:
JavaScript is causing 43ms of forced reflows by reading layout properties after DOM changes, degrading user interaction responsiveness.
How to Fix:
Batch DOM reads and writes separately to avoid layout thrashing. Use CSS transforms instead of changing layout properties like offsetWidth. Implement React's useLayoutEffect for DOM measurements and cache geometric calculations where possible.
