Why It Matters

795 KiB of unused JavaScript is blocking page load for 600ms and delaying LCP by the same amount.

AI Performance Analysis

This Shopify site has severe performance issues with a critically low score of 36/100. The biggest problem is excessive JavaScript execution taking 2.3 seconds, which creates a massive 1,300ms blocking time that prevents users from interacting with the page for nearly 30 seconds. The site is loading 795 KB of unused JavaScript code and suffering from poorly optimized images that could be reduced by 2.7 MB. Removing or deferring unnecessary scripts, compressing images, and implementing better caching could potentially improve the score by 40+ points and dramatically enhance user experience.

Implement Efficient Image Delivery

Medium Impact+12 points estimated
