Optimize Image Caching Strategy
Medium Impact+8 points estimated
Why It Matters
Poor cache configuration wastes 44 KiB on repeat visits and slows down returning user experience.
How to Fix
Configure Next.js image optimization with longer cache headers by setting custom cache-control headers in next.config.js. Use Next.js Image component with priority prop for LCP images. Set cache headers to at least 1 year (31536000 seconds) for static image assets in your CDN or server configuration.

What This Score Means
A score of 67 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 67/100, indicating significant room for improvement. The biggest problem is excessive unused JavaScript (284 KiB) that's blocking the main thread for over 2 seconds and delaying your Largest Contentful Paint to 5.6 seconds - well above the recommended 2.5 seconds. The site is also loading 94% unused CSS and has render-blocking stylesheets that could save an additional 560ms if properly optimized. Cleaning up unused code, implementing code splitting, and deferring non-critical resources could easily boost your score by 25+ points and dramatically improve user experience.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+18 points estimatedWhy It Matters:
Render-blocking CSS delays LCP by 560ms and prevents critical content from displaying immediately.
How to Fix:
Inline critical CSS for above-the-fold content directly in the Next.js page component. Use Next.js dynamic imports to load non-critical CSS asynchronously. Configure your Next.js build to split CSS bundles and defer loading of unused styles using next/dynamic with ssr: false for components not needed immediately.
Remove Unused JavaScript Code
High Impact+15 points estimatedWhy It Matters:
Unused JavaScript wastes 284 KiB and delays LCP by 900ms while blocking the main thread unnecessarily.
How to Fix:
Use Next.js bundle analyzer to identify unused code chunks. Implement dynamic imports for Google Analytics and other third-party scripts using next/script with strategy='afterInteractive'. Split large components into smaller chunks and lazy-load non-critical features using React.lazy() and Suspense.
