Optimize CSS Delivery Strategy
High Impact+18 points estimated
Why It Matters
Render-blocking CSS delays FCP and LCP by 300ms while 94% of the CSS remains unused.
How to Fix
Extract critical CSS for above-the-fold content and inline it in the document head. Use Next.js dynamic imports for component-specific CSS. Remove unused styles from 11e5lkdv_wiez.css or split it into smaller, page-specific bundles.

What This Score Means
A score of 62 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 site has poor performance issues with a score of 62/100. The biggest problem is excessive unused JavaScript (286 KiB), particularly from Google Analytics and Next.js chunks, which is significantly slowing down page loading with an 8.8-second Time to Interactive and 6.9-second Largest Contentful Paint. The site would benefit most from removing unused JavaScript code, optimizing CSS delivery (29 KiB of unused CSS), and implementing better caching strategies for images. Addressing these JavaScript optimization issues alone could save nearly 1 second in load time and dramatically improve the user experience.
Other Optimization Recommendations
Eliminate Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
286 KiB of unused JavaScript is delaying LCP by 1 second and blocking main thread execution.
How to Fix:
Use Next.js dynamic imports to code-split large chunks like 0jwb9_faevhlf.js and 0xt9o5bwccyr4.js. Implement tree shaking in your webpack config to remove dead code. Defer Google Analytics loading until after page interactive using next/script with strategy='afterInteractive'.
Fix Layout Thrashing Issues
Medium Impact+8 points estimatedWhy It Matters:
Forced reflows are consuming 111ms of main thread time and degrading user interaction responsiveness.
How to Fix:
Batch DOM reads and writes in your React components to avoid layout thrashing. Use CSS transforms instead of changing geometric properties. Implement useLayoutEffect carefully and prefer useEffect for non-critical DOM updates in your Next.js components.
