Eliminate PageFly JavaScript Forced Reflows
High Impact+20 points estimated
Why It Matters
PageFly scripts are causing 110ms of forced reflows, blocking the main thread and delaying interactivity.
How to Fix
Access PageFly app settings and disable unused modules or widgets on this product page. Move PageFly scripts to load after DOM content using defer attribute. Consider replacing PageFly sections with native Shopify theme blocks to reduce JavaScript overhead.

AI Performance Analysis
This Shopify site has severe performance problems with a failing score of 0/100, taking 3.4 seconds just to show the first content to users. The biggest issue is an enormous 5.8MB page size, primarily caused by oversized font files (over 1MB just for Merriweather fonts) and unoptimized product images that are loading at 900x900 pixels but only displaying at 322x322 pixels. The site is also suffering from render-blocking CSS files and JavaScript that's causing forced reflows, which makes the page feel sluggish and unresponsive. Immediately compressing and properly sizing the images, optimizing font loading, and addressing the render-blocking resources could dramatically improve load times and user experience.
Other Optimization Recommendations
Optimize Product Images for Performance
High Impact+25 points estimatedWhy It Matters:
Product images are oversized by 271KB and poorly compressed, directly impacting LCP and load speed.
How to Fix:
In Shopify admin, go to Settings > Files and replace current product images with WebP format at 322x322 pixels (actual display size). Enable Shopify's automatic image optimization in theme settings. Use responsive image URLs with proper sizing parameters like ?width=322&height=322.
Defer Render-Blocking CSS Resources
Medium Impact+15 points estimatedWhy It Matters:
CSS files totaling 42KB are blocking initial page render and delaying First Contentful Paint to 3.4 seconds.
How to Fix:
In your Shopify theme code, add media='print' onload="this.media='all'" to non-critical CSS links like plugins.min.css. Inline critical above-the-fold CSS directly in the <head> section. Use Shopify's liquid {% style %} tags for critical product page styles.
