Optimize Cache Headers Configuration
Medium Impact+5 points estimated
Why It Matters
Poor cache lifetimes for images force unnecessary re-downloads on repeat visits.
How to Fix
Configure next.config.js to set longer cache headers for static assets using custom headers. Set cache-control to 'public, max-age=31536000, immutable' for Next.js optimized images. Use CDN caching for course thumbnails with 1-year expiration.

AI Performance Analysis
This Next.js site has poor performance with a score of 70/100, primarily due to excessive unused code that's slowing down the page. The biggest problem is that 281 KiB of unnecessary JavaScript and 29 KiB of unused CSS are being loaded, causing the largest content to take 5.6 seconds to appear—well beyond the recommended 2.5 seconds. The site is also suffering from render-blocking CSS files that delay initial page rendering by an estimated 550ms. Removing unused JavaScript and CSS, along with optimizing the loading sequence of critical resources, could improve the performance score by 15-20 points and dramatically reduce loading times for users.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+12 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying both LCP and FCP by 550ms.
How to Fix:
Move critical CSS inline in your Next.js pages using styled-jsx or CSS-in-JS. Configure next.config.js to split CSS chunks more efficiently. Use next/dynamic with ssr: false for non-critical components that load heavy CSS.
Remove Unused JavaScript Code
High Impact+10 points estimatedWhy It Matters:
281KB of unused JavaScript is increasing LCP by 750ms and blocking main thread execution.
How to Fix:
Use Next.js bundle analyzer to identify unused code in your chunks. Implement dynamic imports for Google Analytics and other third-party scripts. Configure webpack to exclude unused polyfills and legacy browser support since you can target modern browsers.
