Why It Matters
969 KiB of unused JavaScript is wasting 4.45 seconds of load time and significantly impacting LCP performance.
How to Fix
Remove or defer Google Analytics and GTM scripts until after page load using Shopify's Script Tag API. Audit Zendesk chat widget - load it conditionally or after user interaction. Split JavaScript bundles in your theme to only load necessary code per page type.

AI Performance Analysis
This Shopify site has poor performance with a score of 60/100, primarily due to an extremely slow Largest Contentful Paint of 18.3 seconds. The biggest problem is oversized images that are loading at 1000x1000 pixels but only displaying at 289x289 pixels, wasting 560 KB of data and significantly delaying page load. Additionally, the site has nearly 1MB of unused JavaScript from tracking scripts and third-party tools that could be removed or deferred. Optimizing image sizes, removing unnecessary JavaScript, and fixing render-blocking CSS files could improve the performance score by 30+ points and dramatically reduce loading times for users.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+15 points estimatedWhy It Matters:
Three CSS files are blocking initial page render for 1,121ms, delaying first paint and user experience.
How to Fix:
In your Shopify theme's layout/theme.liquid, inline critical CSS for above-the-fold content. Use rel='preload' for base.css and defer non-critical stylesheets. Move WUN-25.css and header-custom.css to load after initial render using media='print' onload='this.media="all"' technique.
Optimize Hero Section Images
Medium Impact+10 points estimatedWhy It Matters:
Hero images are oversized (1000x1000 served at 289x289), wasting 560 KiB and delaying LCP by 50ms.
How to Fix:
Use Shopify's responsive image API to serve appropriately sized images. Replace static image URLs with responsive srcset using sizes='289px'. Add fetchpriority='high' to LCP image and remove loading='lazy' from above-the-fold hero images in your section template.
