Optimize Third-Party JavaScript Performance
High Impact+20 points estimated
Why It Matters
Unused JavaScript from GoKwik and tracking scripts blocks the main thread for 2.2 seconds, severely impacting interactivity.
How to Fix
Remove or defer unused GoKwik cart functionality (225KB unused). Use Google Tag Manager's async loading for tracking scripts. In Shopify admin, audit installed apps and remove unused ones. Implement script loading strategies to prioritize critical functionality first.

AI Performance Analysis
This Shopify site has poor performance with a score of 55/100, primarily due to excessive JavaScript execution that's blocking user interactions for over 28 seconds. The biggest issue is unoptimized JavaScript from third-party services (GoKwik cart, Google Analytics) which accounts for 2.2 seconds of processing time and creates significant layout shifts as images load without proper dimensions. The site is also loading 6.8MB of data with 1MB of unused JavaScript and CSS, while images are oversized for their display dimensions. Minifying JavaScript, optimizing images with proper sizing, and reducing unused code could improve the score by 20-30 points and dramatically reduce the 4.8-second loading time for main content.
Other Optimization Recommendations
Fix Unsized Images Causing Layout Shifts
High Impact+25 points estimatedWhy It Matters:
Images without dimensions cause major layout shifts (CLS 0.105), directly harming user experience and Core Web Vitals.
How to Fix:
Add explicit width and height attributes to all images, especially the hero slider image and partner logos. In your Shopify theme, edit image tags to include dimensions and add fetchpriority='high' to the LCP image. Use CSS aspect-ratio for responsive behavior while maintaining dimensions.
Minify and Optimize CSS Delivery
Medium Impact+10 points estimatedWhy It Matters:
Unminified CSS and unused rules delay LCP by 300ms and waste 76KB of network bandwidth.
How to Fix:
Enable CSS minification in your Shopify theme settings. Remove unused CSS from Font Awesome (99% unused) and GoKwik styles (100% unused). Use Shopify's asset bundling to combine CSS files and reduce render-blocking requests.
