Optimize Product Images for Display Size
Medium Impact+12 points estimated
Why It Matters
Product images are 4x larger than needed (1200x1047 served for 302x302 display) wasting 286 KiB bandwidth.
How to Fix
Use Shopify's responsive image URLs with size parameters like '_302x302_crop_center'. Implement srcset with multiple sizes for different screen densities. Add fetchpriority='high' to the LCP image and ensure it's not lazy loaded.

AI Performance Analysis
This Shopify site has severe performance issues with a critically low score of 12/100. The biggest problem is an extremely slow Time to Interactive of 18 seconds, caused primarily by 332KB of unused JavaScript from bundle files and Google Tag Manager scripts that are blocking the page from becoming functional. The site also suffers from major layout shifts (CLS score of 0.896) due to unsized images in the loading screen, and a painfully slow Largest Contentful Paint of 17.7 seconds. Immediate fixes should focus on removing or deferring unused JavaScript, properly sizing images to prevent layout shifts, and optimizing the bundle loading process - these changes could potentially improve the performance score by 50+ points and dramatically enhance user experience.
Other Optimization Recommendations
Eliminate Layout Shifts from Loading Screen
High Impact+25 points estimatedWhy It Matters:
Massive layout shift (0.896 CLS) from unsized loading spinner image causes poor user experience and terrible CLS score.
How to Fix:
Add explicit width and height attributes to the loading spinner image in div.gbbLoadingScreen. Set fixed dimensions in CSS instead of width: 100% and height: auto. Consider removing the loading screen entirely if the bundle app loads quickly enough.
Reduce Unused JavaScript Bundle Size
High Impact+18 points estimatedWhy It Matters:
332 KiB of unused JavaScript (65% waste in bundle file) delays LCP by 2.4 seconds and blocks main thread.
How to Fix:
Configure the Easy Bundle app to only load required JavaScript modules. Use dynamic imports for bundle functionality that's not immediately needed. Contact the app developer about code splitting options to reduce the initial bundle size.
