Optimize Critical JavaScript Execution

High Impact+25 points estimated

Why It Matters

JavaScript execution takes 5.2 seconds and blocks the main thread for 1.5 seconds, severely impacting user interactions and page responsiveness.

How to Fix

Remove unused code from the Releasit COD form extension (239KB wasted). Defer Facebook Pixel initialization until after page load. Use Shopify's Script Tag API to load non-critical third-party scripts asynchronously after the page becomes interactive.

What This Score Means

A score of 33 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis

This Shopify site has severe performance issues with a critically low score of 33/100. The biggest problem is extremely slow JavaScript execution taking over 15 seconds of main thread work, which is blocking user interactions and causing a devastating 1.5-second delay before users can click anything. The site is loading nearly 7MB of data including massive unoptimized images and over 350KB of unused JavaScript code, while legacy Facebook tracking scripts are adding unnecessary overhead. Immediately reducing JavaScript payloads, compressing images, and removing unused code could improve the score by 40+ points and transform this from an unusable to acceptable user experience.

Other Optimization Recommendations

Compress and Optimize Images

High Impact+20 points estimated

Why It Matters:

Oversized images account for 3.8MB of wasted bytes and delay visual content rendering, directly impacting LCP performance.

How to Fix:

Use Shopify's built-in image optimization by updating liquid templates to use responsive image sizing with proper srcset attributes. Increase compression settings in your image editing workflow before upload. Implement fetchpriority='high' on the LCP image element to prioritize its loading.

Eliminate Render-Blocking Resources

Medium Impact+12 points estimated

Why It Matters:

CSS files are blocking initial page render by 410ms, delaying when users can see meaningful content.

How to Fix:

Inline critical CSS for above-the-fold content directly in the Shopify theme template. Use Shopify's asset_url filter with async loading for non-critical stylesheets. Remove unused CSS rules from base.css (43KB of unused styles) using Shopify's theme inspector.
