Optimize Image Delivery and Sizing
High Impact+15 points estimated
Why It Matters
Images waste 942KB and delay LCP by 4.1 seconds due to oversized files and outdated formats.
How to Fix
Convert all JPEG images to WebP format for 50-70% size reduction. Resize background images to match their display dimensions (currently serving 1000x496 images for 665x330 display). Add width and height attributes to prevent layout shifts. Implement responsive images with srcset for different screen sizes.

What This Score Means
A score of 64 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 e-commerce website has poor performance with a score of 64/100, primarily due to an extremely slow Largest Contentful Paint of 20.4 seconds and Time to Interactive of 23.3 seconds. The biggest issues are excessive unused CSS (130 KiB wasted) and JavaScript (493 KiB wasted), particularly from Google reCAPTCHA scripts that are loaded but barely used, along with render-blocking resources that delay initial page rendering by 580ms. Additionally, the site is loading a massive 4.6 MB of data per page visit, with poorly optimized images that could be reduced by 942 KiB through modern formats like WebP and proper sizing. Cleaning up unused code, optimizing images, and implementing better caching strategies could dramatically improve load times and user experience.
Other Optimization Recommendations
Remove Unused CSS and JavaScript
High Impact+18 points estimatedWhy It Matters:
Unused code blocks rendering for 450ms and wastes 634KB of bandwidth, directly delaying LCP by 1.5 seconds.
How to Fix:
Audit your merged CSS file to remove 94% unused styles, especially from reCAPTCHA components not needed on homepage. Use tools like PurgeCSS to eliminate unused JavaScript from Google Analytics and reCAPTCHA. Consider loading reCAPTCHA only when contact forms are actually displayed.
Eliminate Render-Blocking Resources
High Impact+12 points estimatedWhy It Matters:
CSS and JavaScript files block initial page render for 580ms, preventing users from seeing content quickly.
How to Fix:
Inline critical CSS for above-the-fold content directly in HTML. Defer non-critical CSS using media='print' onload='this.media="all"' technique. Move JavaScript files like requirejs-config.min.js to load after HTML parsing using defer attribute. Preload the LCP background image with fetchpriority='high'.
