Optimize JavaScript Execution Time
Medium Impact+12 points estimated
Why It Matters
1.8 seconds of JavaScript execution time is blocking the main thread and increasing Total Blocking Time by 400ms.
How to Fix
Break up large JavaScript tasks using React.Suspense and lazy loading for heavy components. Move non-critical JavaScript execution to Web Workers where possible. Use React.useMemo and useCallback to prevent unnecessary re-renders that cause forced reflows.

AI Performance Analysis
This Next.js site has poor performance with a score of 65/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking 1.8 seconds, combined with 285 KiB of unused JavaScript code that's unnecessarily slowing down page loads and causing your Largest Contentful Paint to reach 5.8 seconds. The site is also suffering from render-blocking CSS files that could save 580ms if properly optimized, plus nearly 30 KiB of unused CSS that should be removed. Focusing on reducing JavaScript bundle sizes, removing unused code, and optimizing CSS delivery could improve your score by 20-30 points and dramatically speed up the site for users.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+18 points estimatedWhy It Matters:
CSS files are blocking page render for 580ms, directly delaying LCP by 600ms and FCP by 600ms.
How to Fix:
Use Next.js built-in CSS optimization by moving critical CSS inline or using CSS-in-JS solutions like styled-components. Split the large 31KB CSS file into component-specific modules. Implement critical CSS extraction using tools like critical or Critters in your Next.js build process.
Reduce Unused JavaScript Bundles
High Impact+15 points estimatedWhy It Matters:
285KB of unused JavaScript is wasting bandwidth and delaying LCP by 750ms.
How to Fix:
Use Next.js dynamic imports to code-split large components and defer loading until needed. Remove unused Google Tag Manager features or load them asynchronously. Implement tree-shaking by ensuring your build process eliminates dead code from the 74% unused chunks.
