Fix Render Blocking Resources
High Impact+15 points estimated
Why It Matters
Critical rendering is blocked for 310ms by CSS and JavaScript files that could be deferred.
How to Fix
Move non-critical CSS like accelerated-checkout-backwards-compat.css to load after first paint. Inline critical above-the-fold CSS directly in the HTML. Use Shopify's Script Tag API to load third-party scripts like Visually.io after page interactive.

What This Score Means

AI Performance Analysis
This Shopify store has severe performance issues with a dismal score of 33/100. The biggest problem is excessive JavaScript execution taking over 27 seconds of main thread work, causing the page to become interactive only after 27 seconds and delaying the Largest Contentful Paint to nearly 14 seconds. The site is loading 345KB of unused JavaScript (primarily from Google Tag Manager and analytics scripts) and 33KB of unused CSS, while also suffering from render-blocking requests that delay initial page rendering by 310ms. Removing unused code, optimizing JavaScript delivery, and implementing proper caching could potentially improve the score by 40+ points and dramatically enhance user experience.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+25 points estimatedWhy It Matters:
345 KiB of unused JavaScript is delaying LCP by 750ms and blocking user interactions.
How to Fix:
Audit Google Tag Manager scripts and remove unused tracking codes. Use Shopify's built-in analytics instead of redundant GTM implementations. Defer non-critical third-party scripts like Klaviyo and Northbeam until after page load using async/defer attributes.
Optimize Image Delivery Performance
High Impact+20 points estimatedWhy It Matters:
Images are oversized and poorly compressed, wasting 255 KiB and delaying LCP by 150ms.
How to Fix:
Enable Shopify's automatic WebP conversion in theme settings. Resize product images to match display dimensions (525x318 instead of 684x414). Implement responsive images using Shopify's image transformation URLs with appropriate srcset attributes.
