Eliminate Render-Blocking CSS Resources
High Impact+18 points estimated
Why It Matters
CSS files are delaying both LCP and FCP by 1,530ms, preventing critical content from rendering.
How to Fix
Inline critical CSS directly in the HTML head for above-the-fold content. Defer non-critical CSS like AOS animations and Splide carousel styles using media='print' onload technique. Remove 87% unused CSS from main.min.css or split into page-specific stylesheets.

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 issues that are hurting user experience. The biggest problem is excessive JavaScript execution time (4.4 seconds) combined with massive unused JavaScript code (1,299 KiB wasted), which is causing an extremely slow Time to Interactive of 26.3 seconds and blocking the main thread for 6 seconds. Additionally, the site is suffering from unoptimized images that waste 621 KiB and poor font loading that delays content visibility by 190ms. Reducing JavaScript payloads, optimizing image compression and sizing, and implementing proper font-display settings could improve performance by 30+ points and dramatically reduce load times.
Other Optimization Recommendations
Optimize Critical Image Delivery
High Impact+15 points estimatedWhy It Matters:
Images are blocking LCP for 350ms and wasting 621 KiB with poor compression and oversized dimensions.
How to Fix:
Compress the Filters-not-logged-in@2x.png image to reduce its 353KB size by ~75%. Serve appropriately sized images (637x804 instead of 1179x1489). Add explicit width and height attributes to prevent layout shifts. Use modern formats like WebP for better compression.
Reduce JavaScript Execution Overhead
High Impact+12 points estimatedWhy It Matters:
JavaScript execution blocks the main thread for 4.4 seconds, causing 1,690ms Total Blocking Time and poor interactivity.
How to Fix:
Defer reCAPTCHA loading until user interaction is needed. Remove duplicate reCAPTCHA script references (3 identical 372KB files detected). Break up long JavaScript tasks by using setTimeout or requestIdleCallback for non-critical operations. Consider lazy-loading the Rocket Loader script.
