Eliminate Render-Blocking CSS
High Impact+3 points estimated
Why It Matters
CSS file blocks initial page render for 150ms, directly delaying both LCP and FCP.
How to Fix
Inline critical CSS for above-the-fold content in the HTML head. Move non-critical CSS to load asynchronously using media='print' onload='this.media="all"' technique. Consider splitting CSS into critical and non-critical bundles in your build process.

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 website has excellent performance with a score of 94/100, but there are still some optimization opportunities. The biggest issue is render-blocking CSS that's delaying page loading by 150ms, which affects both your Largest Contentful Paint (2.7s) and First Contentful Paint times. Additionally, you have 69 KiB of unused JavaScript from analytics and your main app bundle that could be optimized or deferred to improve loading speed. Addressing the render-blocking CSS and trimming unused JavaScript could push your already strong performance score even higher and reduce your Speed Index from 4.2 seconds.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+2 points estimatedWhy It Matters:
69KB of unused JavaScript wastes 300ms of processing time and delays LCP by 300ms.
How to Fix:
Analyze Matomo analytics script and remove unused features or switch to GA4. Use tree-shaking in your build process to eliminate dead code from app-B75yEAbr.js. Implement code splitting to load only required JavaScript per page.
Fix Forced Layout Reflows
Medium Impact+1 point estimatedWhy It Matters:
JavaScript queries geometric properties after DOM changes, causing 33ms of unnecessary layout work.
How to Fix:
Batch DOM reads and writes to avoid layout thrashing in your JavaScript. Cache geometric property values instead of repeatedly querying offsetWidth/offsetHeight. Use CSS transforms instead of changing layout properties when possible.
