Optimize Critical Resource Loading

High Impact+25 points estimated

Why It Matters

Render-blocking resources delay First Contentful Paint by 2.2 seconds, preventing users from seeing content.

How to Fix

In your Shopify theme's theme.liquid, add preload tags for critical CSS files like base.css. Move TypeKit font loading to use font-display: swap in CSS. Inline critical above-the-fold CSS directly in the HTML head to eliminate render blocking.

AI Performance Analysis

This Shopify site has severe performance issues with a critically low score of 29/100. The biggest problem is an enormous 3.3MB of unused JavaScript that's blocking the page from loading properly, causing an extremely slow Largest Contentful Paint of 49.5 seconds and making the site nearly unusable on mobile devices. The site is loading massive amounts of unnecessary code from third-party services and oversized images that are much larger than needed for their display size. Removing unused JavaScript, properly sizing images, and cleaning up the excessive number of third-party scripts could improve the performance score by 40+ points and transform this from an unusable site into a fast, user-friendly experience.

Other Optimization Recommendations

Remove Unused JavaScript Code

High Impact+35 points estimated

Why It Matters:

3.3 MB of unused JavaScript is delaying LCP by 12.6 seconds and blocking the main thread for 11.3 seconds.

How to Fix:

Audit Pickrr boost UI integration and remove unused chunks (712.4b894668.chunk.js shows 97% waste). In Shopify admin, review and uninstall unused apps. Use code splitting to load JavaScript only when needed. Consider replacing heavy third-party scripts with lighter alternatives.

Implement Responsive Image Sizing

Medium Impact+12 points estimated

Why It Matters:

Press cover images are 7x larger than needed (2251x1845 served for 320x320 display), wasting 4.4 MB of bandwidth.

How to Fix:

In Shopify admin, upload multiple image sizes using Shopify's responsive image system. Update liquid templates to use {% render 'responsive-image' %} snippet. Add srcset attributes with appropriate breakpoints (320w, 640w, 1280w) for press cover images.
