Eliminate Unused JavaScript Code
High Impact+25 points estimated
Why It Matters
378 KiB of unused JavaScript is blocking the main thread and delaying LCP by 1.4 seconds.
How to Fix
Remove or defer Facebook Pixel (119KB unused), Google Analytics scripts (127KB unused), and Shopify Chat widget until user interaction. Use Shopify's native analytics instead of multiple tracking scripts. Implement code splitting for app extensions to load only when needed.

AI Performance Analysis
This Shopify store has poor performance with a critically low score of 44/100. The biggest problem is excessive JavaScript execution taking 2.3 seconds, which severely impacts loading speed with pages taking nearly 21 seconds to become interactive and 19.4 seconds for the largest content to appear. The site is loading 378 KiB of unused JavaScript code and suffering from unoptimized images that could be reduced by 431 KiB, while render-blocking CSS files are delaying the initial page display by 660ms. Removing unused JavaScript, compressing and properly sizing images, and deferring non-critical CSS would dramatically improve user experience and could potentially double the performance score.
Other Optimization Recommendations
Optimize Image Delivery Performance
High Impact+18 points estimatedWhy It Matters:
Oversized images waste 431 KiB and delay LCP by 300ms with poor compression ratios.
How to Fix:
In Shopify Admin, enable automatic WebP conversion in Settings > Files. Use responsive image sizes - serve 372x372 images for mobile display instead of 800x800. Compress product images to 80-85% quality before upload. Add explicit width/height attributes to prevent layout shifts.
Reduce JavaScript Execution Time
High Impact+12 points estimatedWhy It Matters:
2.3 seconds of JavaScript execution blocks user interactions and creates 490ms of blocking time.
How to Fix:
Minify JavaScript files in Shopify app extensions (18KB savings available). Remove or lazy-load non-essential apps like trust badges and bundles until after page load. Use Shopify's Script Tag API to defer third-party scripts until user interaction.
