AI Performance Analysis

This Shopify site has severe performance issues with a score of just 26/100. The biggest problem is excessive JavaScript execution time (13.4 seconds) that's blocking user interactions, causing your Time to Interactive to reach a devastating 40.2 seconds. The site is also suffering from render-blocking CSS and font files that delay initial content display by over 1 second. To fix this, you should reduce JavaScript payloads, defer non-critical scripts, optimize font loading with proper display properties, and minify your CSS files - these changes could potentially improve your score by 40+ points and dramatically enhance user experience.

Other Optimization Recommendations

Eliminate Render Blocking Resources

High Impact+25 points estimated

Why It Matters:

Blocking CSS and fonts delay First Contentful Paint by 1.14 seconds and prevent content from rendering.

How to Fix:

Inline critical CSS for above-the-fold content in your Shopify theme's head section. Use font-display: swap for Google Fonts to prevent invisible text. Move non-critical CSS files to load asynchronously using media='print' onload='this.media="all"' technique.

Optimize Image Delivery

Medium Impact+8 points estimated

Why It Matters:

Oversized images waste 493KB of bandwidth and delay LCP by 150ms.

How to Fix:

Use Shopify's responsive image system with proper srcset attributes for the hero banner. Compress the made_for_you_mobile.webp image from 241KB to under 100KB. Implement lazy loading for product images below the fold using loading='lazy' attribute.
