Increase Hero Image Compression
Medium Impact+3 points estimated
Why It Matters
The backdrop image wastes 11 KiB and impacts perceived loading performance.
How to Fix
Re-encode the backdrop-home-864.avif file with higher compression settings using tools like Squoosh or ImageOptim. Set quality to 75-80% instead of current settings. Consider using a progressive JPEG fallback for better browser support while maintaining the AVIF primary source.

AI Performance Analysis
This website performs reasonably well with a score of 85/100, but has room for improvement in loading speed. The biggest issue is excessive unused JavaScript, particularly from Google Analytics and React components, which wastes 129 KB and delays content loading by 300ms. The site also suffers from slow initial content display, taking 3.2 seconds for First Contentful Paint and 3.5 seconds for the largest content to appear. Removing unused JavaScript code and compressing the main backdrop image (which could save an additional 11 KB) would provide the most significant performance gains and improve user experience.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+8 points estimatedWhy It Matters:
129 KiB of unused JavaScript delays LCP by 300ms and blocks user interactions.
How to Fix:
Tree-shake unused code from Google Analytics by switching to gtag with minimal config. Code-split your React bundle to load only critical components initially. Defer Google Tag Manager loading until after page interaction or use a timeout.
Optimize Critical Resource Loading
High Impact+6 points estimatedWhy It Matters:
Slow First Contentful Paint at 3.2 seconds delays when users see meaningful content.
How to Fix:
Inline critical CSS for above-the-fold content to eliminate render-blocking resources. Preload your main JavaScript bundle using <link rel='preload'> in the HTML head. Use resource hints like dns-prefetch for external domains beyond the current preconnects.
