Remove Unused JavaScript and Polyfills
High Impact+18 points estimated
Why It Matters
297KB of unused JavaScript is blocking the main thread and delaying LCP by 900ms.
How to Fix
Update your Next.js target to 'es2017' or newer in next.config.js to eliminate unnecessary polyfills for modern browsers. Use webpack-bundle-analyzer to identify unused code in your chunks. Implement code splitting with next/dynamic for large components like analytics that aren't immediately needed.

What This Score Means
A score of 64 falls in the "Needs Improvement" 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/React site has poor performance with a score of 64/100, primarily due to excessive JavaScript that's blocking the page from becoming interactive. The biggest issue is unused JavaScript (297 KiB) combined with legacy polyfills (43 KiB) that modern browsers don't need, causing your Largest Contentful Paint to suffer at 5.9 seconds and Time to Interactive to crawl at 9.2 seconds. The site is also loading 34 KiB of unused CSS and has render-blocking stylesheets that delay initial page rendering by 560ms. Cleaning up your JavaScript bundles, removing unnecessary polyfills, and optimizing your CSS could easily improve your score by 20-30 points and dramatically speed up the user experience.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+12 points estimatedWhy It Matters:
CSS files are blocking initial page render and delaying LCP by 550ms.
How to Fix:
Update your Next.js build configuration to inline critical CSS for above-the-fold content. Use next/dynamic with ssr: false for non-critical components. Split the large 34KB CSS bundle by implementing CSS modules or component-specific styles to reduce the initial blocking payload.
Fix Forced Layout Reflows
Medium Impact+8 points estimatedWhy It Matters:
JavaScript is triggering 151ms of forced reflows, blocking user interactions and increasing Total Blocking Time.
How to Fix:
Batch DOM reads and writes by collecting all measurements before making style changes. Use CSS transforms instead of changing geometric properties like offsetWidth. Consider using React's useLayoutEffect sparingly and prefer useEffect for non-critical layout updates.
