AI Performance Analysis
This website has poor performance with a score of 74/100, primarily due to extremely slow loading times with the Largest Contentful Paint taking 12.8 seconds. The biggest issues are oversized images (340 KB in potential savings) that aren't using modern formats like WebP, and a massive amount of unused CSS code (55 KB waste) that's blocking the page from rendering quickly. The site is also loading too much data overall at 3.4 MB, which significantly impacts load times especially on slower connections. Fixing these image optimization and CSS issues could dramatically improve the user experience and boost the performance score by 15-20 points.
Other Optimization Recommendations
Remove Unused CSS Rules
High Impact+12 points estimatedWhy It Matters:
91% of your CSS is unused, blocking render and delaying LCP by 300ms.
How to Fix:
Use PurgeCSS or UnCSS to remove unused styles from your main stylesheet. Split critical above-the-fold CSS and inline it in the head. Defer non-critical CSS using media='print' onload='this.media="all"' technique.
Defer Render-Blocking Resources
Medium Impact+8 points estimatedWhy It Matters:
CSS files are blocking first paint and delaying page rendering by 270ms.
How to Fix:
Add async or defer attributes to non-critical JavaScript files. Inline critical CSS directly in the HTML head section. Move render-blocking CSS to load after first contentful paint using preload with onload handler.
