Remove Render-Blocking CSS
Medium Impact+8 points estimated
Why It Matters
CSS files block initial page render and delay First Contentful Paint by 600ms.
How to Fix
Inline critical above-the-fold CSS directly in the HTML head. Load non-critical CSS asynchronously using media='print' onload='this.media="all"' technique. Consider removing unused CSS from the reCAPTCHA stylesheet which is 96% unused.

What This Score Means
A score of 37 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 severe performance issues with a critically low score of 37/100, indicating major user experience problems. The biggest issue is massive JavaScript bloat, particularly from Google reCAPTCHA which is loading over 600KB of unused code and taking 2.2 seconds to execute, severely delaying page interactivity to 13.8 seconds. Additionally, images are poorly optimized with oversized files wasting 106KB of downloads, and render-blocking CSS is preventing content from appearing quickly. Removing unused JavaScript, properly sizing images, and deferring non-critical resources could improve the score by 30+ points and reduce load times by over 5 seconds.
Other Optimization Recommendations
Eliminate Unused JavaScript Resources
High Impact+25 points estimatedWhy It Matters:
Removing 627KB of unused JavaScript could improve LCP by 5.4 seconds and reduce main thread blocking.
How to Fix:
Remove or defer loading of Google reCAPTCHA until user interaction is needed. Implement async/defer attributes on tracking scripts. Split critical JavaScript from non-critical code and load non-critical scripts after page interactive event.
Optimize Hero Image Delivery
High Impact+12 points estimatedWhy It Matters:
The main hero image is oversized by 81KB and directly impacts LCP timing.
How to Fix:
Resize the hero image from 1200x800 to match its display size of 380x253 for mobile. Generate properly sized responsive images for different breakpoints. Consider using next-gen formats like AVIF for additional compression.
