Eliminate Unused JavaScript Code
High Impact+25 points estimated
Why It Matters
811 KiB of unused JavaScript is causing a 3.9 second delay in LCP and significantly blocking page rendering.
How to Fix
Analyze your main JavaScript bundle (index-B5popVF8.js) to identify and remove unused code - 64% is currently unused. Use webpack-bundle-analyzer or similar tools to identify dead code. Consider code splitting to load only necessary JavaScript for each page. Remove or defer the Google Sign-In client if not immediately needed.

What This Score Means
A score of 41 falls in the "Poor" 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 41/100, indicating significant user experience issues. The biggest problem is excessive unused JavaScript (811 KiB) that's delaying page interactivity by nearly 4 seconds, combined with a severely oversized logo image that's 87 KB larger than needed for its display size. The site takes 9.6 seconds to become fully interactive and show its main content, which is far too slow for users. Immediate fixes should focus on removing unused JavaScript code, properly sizing the logo image, and implementing basic caching strategies, which together could improve load times by several seconds and dramatically boost the performance score.
Other Optimization Recommendations
Optimize Logo Image Delivery
High Impact+15 points estimatedWhy It Matters:
The LCP logo image is 87KB larger than needed and missing optimization attributes, delaying page rendering by 2.7 seconds.
How to Fix:
Resize logo.png from 1376x896 to actual display dimensions of 333x217 pixels. Convert to WebP format for better compression. Add fetchpriority='high' attribute to prioritize loading. Add explicit width and height attributes to prevent layout shifts.
Implement Proper Browser Caching
Medium Impact+8 points estimatedWhy It Matters:
No cache headers are set for critical assets totaling 1.35MB, forcing full downloads on every visit.
How to Fix:
Configure your web server to set cache headers for static assets - set 1 year cache for CSS/JS files with versioned filenames. Set appropriate cache headers for images (30 days minimum). Use ETags for better cache validation. This will dramatically improve repeat visit performance.
