Remove Unused CSS and JavaScript
Medium Impact+10 points estimated
Why It Matters
82% of CSS (11 KiB) and 43% of JavaScript (44 KiB) remain unused, adding 600ms to load times unnecessarily.
How to Fix
Use PurgeCSS or similar tools to remove unused CSS rules from your stylesheet. Split JavaScript into critical and non-critical chunks, loading only essential code initially. Implement code splitting at the component level to load features on-demand.

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 website has poor performance with a score of 62/100, showing significant loading delays with pages taking nearly 10 seconds to become fully interactive. The biggest problem is inefficient caching of font files (Inter fonts), which is wasting 1,800 KB of data and adding over 9 seconds to loading time - fixing this single issue could dramatically improve performance. Additional quick wins include optimizing oversized images (124 KB savings), removing 83% of unused CSS code, and eliminating 44 KB of unnecessary JavaScript code. These combined improvements could potentially boost the performance score by 25-30 points and provide users with a much faster, more responsive experience.
Other Optimization Recommendations
Implement Efficient Font Caching Strategy
High Impact+25 points estimatedWhy It Matters:
Font resources lack cache headers causing 1,802 KiB to re-download on every visit, delaying LCP by 9.15 seconds.
How to Fix:
Configure your web server to set cache-control headers for font files with max-age=31536000 (1 year). Add proper ETags and Last-Modified headers. Consider using a CDN with automatic caching for font delivery.
Optimize Image Sizing and Delivery
High Impact+15 points estimatedWhy It Matters:
Oversized images waste 124 KiB bandwidth and delay LCP by 450ms due to serving full-resolution images for smaller display sizes.
How to Fix:
Generate responsive image versions at multiple sizes (380w, 665w, 1024w, 1536w) using your build process. Implement srcset attributes with appropriate sizes. Use picture elements for art direction on different viewports. Compress images further while maintaining quality.
