High Impact+15 points estimated
Why It Matters
57KB of unused JavaScript delays LCP by 150ms and blocks the main thread unnecessarily.
How to Fix
Remove or defer Facebook Pixel (fbevents.js) if not essential for tracking. Use Shopify's native analytics instead of third-party tracking scripts. Load remaining scripts conditionally using Shopify's Script Tag API or move to footer with defer attribute.

AI Performance Analysis
This Shopify site has poor performance with a score of 56/100, primarily due to severe layout shift issues. The biggest problem is an unsized image that causes a major layout shift (CLS score of 0.369), making the page feel unstable as content jumps around while loading. The site also suffers from a very slow Largest Contentful Paint of 7.0 seconds and excessive unused JavaScript from Facebook tracking scripts. Adding proper width and height attributes to images, optimizing JavaScript delivery, and reducing render-blocking CSS requests could dramatically improve both the performance score and user experience.

Fix Image Layout Shifts
High Impact+18 points estimatedWhy It Matters:
Unsized images cause a 0.369 CLS score and poor user experience as content jumps during loading.
How to Fix:
Add explicit width='240' and height='240' attributes to the design_8.png image element in your Shopify theme. Update all product images in your liquid templates to include dimensions. Use CSS aspect-ratio property as a fallback for responsive images.
Optimize Asset Caching
Medium Impact+8 points estimatedWhy It Matters:
Poor cache lifetimes force repeated downloads of 125KB assets, slowing repeat visits by 600ms.
How to Fix:
Configure longer cache headers for static assets through your CDN or hosting provider. Set Facebook scripts to load from a cached version or implement service worker caching. Use Shopify's asset pipeline to version and cache theme assets efficiently.
