Reduce Unused JavaScript Code
High Impact+20 points estimated
Why It Matters
Google Tag Manager scripts contain 1.7MB of unused code, blocking the main thread and delaying LCP by 6.5 seconds.
How to Fix
Access Google Tag Manager and audit all active tags - remove any unused tracking pixels or analytics. Use GTM's built-in triggers to load non-critical scripts only after page interaction. In your Shopify theme, defer GTM loading by adding 'defer' attribute to the script tag or load it via Shopify Scripts API after critical content.

AI Performance Analysis
This Shopify site has severe performance issues with a score of 40/100, indicating extremely slow loading times that will frustrate users. The biggest problem is massively oversized images that are completely unoptimized - review images are being served at 3500x6000+ pixel dimensions but displayed at only 188x250 pixels, wasting nearly 6MB of data and causing the page's largest content to take a devastating 23+ seconds to load. Additionally, the site is loading 1.7MB of unused JavaScript from Google Analytics and Facebook tracking scripts, adding another 6+ seconds of delay. Properly resizing images to match their display dimensions, converting them to modern WebP format, and removing unused JavaScript could easily improve the performance score by 30+ points and reduce load times from 23 seconds to under 5 seconds.
Other Optimization Recommendations
Optimize Review Section Images
High Impact+25 points estimatedWhy It Matters:
Three review images are 6MB total but displayed at only 188px wide, causing massive waste and delaying LCP by 6.5 seconds.
How to Fix:
In your Shopify admin, go to Settings > Files and replace the review images with properly sized versions (188x334px max). Use Shopify's image transformation by adding '_188x334' before the file extension in your theme code. Convert to WebP format using apps like TinyIMG or Booster for 50-70% size reduction.
Add Image Dimensions Explicitly
Medium Impact+8 points estimatedWhy It Matters:
Missing width/height on review images causes layout shifts as content jumps when images load, hurting user experience.
How to Fix:
Edit your Shopify theme's review section template (likely in sections/ folder). Add explicit width='188' and height='334' attributes to all review image tags. Also add CSS with aspect-ratio: 188/334 for better responsive behavior and to prevent layout shifts during loading.
