Optimize Image Delivery and Sizing
High Impact+20 points estimated
Why It Matters
Oversized images waste 2.5 MB of bandwidth and significantly delay LCP, especially the hero image.
How to Fix
Use Shopify's responsive image system with proper srcset attributes for product images. Resize images to match their display dimensions - currently serving 1460x1459px images for 412x531px containers. Add fetchpriority='high' to the LCP hero image and ensure WebP format is used consistently across all images.

What This Score Means

AI Performance Analysis
This Shopify site has poor performance with a score of 47/100. The biggest problem is excessive JavaScript execution that takes 1.6 seconds, blocking the main thread for 5.7 seconds and severely delaying page interactivity until 37 seconds. The site loads a massive 465 KiB of unused JavaScript from third-party widgets and tracking scripts, while render-blocking resources delay initial paint by 1.5 seconds. Removing unused JavaScript, optimizing third-party scripts, and fixing render-blocking resources could improve the score by 30+ points and dramatically reduce loading times from the current 32.5 seconds for largest content paint.
Other Optimization Recommendations
Remove Unused JavaScript Resources
High Impact+25 points estimatedWhy It Matters:
Unused JavaScript consumes 465 KiB and delays LCP by 1.95 seconds while blocking main thread execution.
How to Fix:
Remove or defer unused third-party scripts like Gotolstoy widget (175 KiB unused), Appstle subscription script (49 KiB unused), and Google Analytics tracking. Use Shopify's Script Tag API to load only necessary scripts conditionally. Audit app installations and remove unused Shopify apps contributing to JavaScript bloat.
Eliminate Render-Blocking Resources
High Impact+15 points estimatedWhy It Matters:
Critical rendering path is blocked by 1.45 seconds due to external CSS and JavaScript files.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML. Move non-critical third-party resources like Split-type animations and external widget CSS to load asynchronously. Use Shopify's {% render %} tag to inline essential styles and defer remaining stylesheets with media='print' onload technique.
