Remove Unused JavaScript Code
High Impact+20 points estimated
Why It Matters
706 KiB of unused JavaScript is loaded unnecessarily, wasting 3.66 seconds and blocking user interactions.
How to Fix
Use Next.js dynamic imports to code-split large vendor chunks like vendors-d1fb907c (142KB unused). Analyze your bundle with @next/bundle-analyzer and remove unused dependencies. Implement lazy loading for components not needed on initial page load using next/dynamic with ssr: false.

What This Score Means
A score of 41 falls in the "Poor" 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 severe performance issues with a score of 41/100. The biggest problem is an extremely slow Largest Contentful Paint of 17.2 seconds, primarily caused by render-blocking CSS files that are delaying page loading by 750ms and massive amounts of unused JavaScript (706 KiB). The site is also experiencing significant layout shifts (0.27 CLS score) from unsized images and elements moving around as the page loads. Optimizing CSS delivery, removing unused JavaScript, and fixing layout shift issues could dramatically improve performance and user experience by several seconds.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+25 points estimatedWhy It Matters:
Three CSS files are blocking initial render for 750ms, directly delaying LCP by 3.65 seconds.
How to Fix:
Implement critical CSS inlining in your Next.js app by extracting above-the-fold styles into a <style> tag in the document head. Use next/dynamic to code-split and lazy load non-critical CSS. Consider using @next/bundle-analyzer to identify which CSS chunks can be deferred.
Fix Layout Shift Issues
Medium Impact+10 points estimatedWhy It Matters:
Multiple layout shifts (CLS: 0.27) are caused by unsized images and dynamic content loading, hurting user experience.
How to Fix:
Add explicit width and height props to all Next.js Image components to reserve space. Use CSS aspect-ratio or min-height for dynamic content containers. Implement skeleton screens for the main content area that's causing the largest shift (0.18 CLS impact).
