Eliminate Render Blocking CSS
High Impact+15 points estimated
Why It Matters
Your CSS file is blocking initial render and delaying LCP by 350ms, preventing users from seeing content.
How to Fix
Inline critical above-the-fold CSS directly in the HTML head section. Load the remaining CSS (index-BjYuMvG_.css) asynchronously using media='print' onload technique. Remove the 90% unused CSS rules or split into component-specific stylesheets.

What This Score Means
A score of 68 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 concerning performance issues with a score of 68/100, indicating significant room for improvement. The biggest problem is excessive unused JavaScript code, which is wasting 84 KiB and slowing down page loading by nearly half a second - over 43% of the main JavaScript file isn't actually being used. The site also suffers from render-blocking CSS that delays content appearance by 350ms and unused CSS rules consuming an additional 33 KiB of bandwidth. These issues are causing slow loading times, with the largest content not appearing until 5.6 seconds and first content taking 3.5 seconds to show, which will frustrate users and hurt search rankings.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+18 points estimatedWhy It Matters:
84KB of unused JavaScript is blocking LCP by 450ms and delaying first paint by the same amount.
How to Fix:
Audit your main bundle (index-DH6OJpmO.js) to remove 43% unused code and InfoHome component's 71% unused code. Use tree-shaking in your build process and code-splitting to load components only when needed. Consider lazy loading the InfoHome component if it's below the fold.
Optimize Network Request Chain
Medium Impact+8 points estimatedWhy It Matters:
Your longest dependency chain takes 1.46 seconds, creating unnecessary delays in content loading.
How to Fix:
Preload critical JavaScript files like Utility-B4Vngspv.js and InfoHome-MVBnKouZ.js using <link rel='preload'>. Bundle frequently used small JavaScript files together to reduce network requests. Consider inlining small utilities directly in your main bundle.
