High Impact+12 points estimated
Why It Matters
Blocking CSS files delay First Contentful Paint by 410ms, slowing initial page render.
How to Fix
Inline critical CSS for above-the-fold content directly in your Shopify theme. Use media='print' onload technique to defer non-critical CSS like cart-drawer.css. Remove unused CSS rules that account for 73KB of wasted bytes.

AI Performance Analysis
This Shopify site has poor performance with a score of 50/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking 5.3 seconds of main thread work, which is blocking the page from becoming interactive for nearly 30 seconds and causing a painfully slow Speed Index of 9.6 seconds. The site is also suffering from major layout shifts (CLS of 0.304) due to unsized images and web font loading, plus it's loading 1+ MB of unused JavaScript and CSS that could be removed. Reducing JavaScript payloads, properly sizing images, and eliminating render-blocking resources could improve the performance score by 30+ points and dramatically enhance user experience.
Other Optimization Recommendations
Fix Layout Shifts from Images
High Impact+15 points estimatedWhy It Matters:
Unsized images cause major layout shifts (CLS 0.304) that hurt user experience and rankings.
How to Fix:
Add explicit width and height attributes to your hero banner image and all carousel images. In Shopify theme code, modify image tags to include dimensions. Add fetchpriority='high' to your LCP image to prioritize loading.
Reduce JavaScript Execution Time
High Impact+18 points estimatedWhy It Matters:
JavaScript blocks the main thread for 5.3 seconds, preventing user interactions and delaying page responsiveness.
How to Fix:
Remove or defer the large Gokwik cart script (247KB) that's 91% unused. Audit your Shopify apps and remove unnecessary ones. Use Shopify's Script Tag API to load non-critical scripts after page load.
