Reduce JavaScript Execution Time

High Impact+25 points estimated

Why It Matters

6.2 seconds of main-thread work blocks user interactions and delays all Core Web Vitals significantly.

How to Fix

Remove unused JavaScript from Shopify Chat widget (19KB), Klaviyo (18KB), and YouTube embeds (142KB). Use Shopify's Script Tag API to defer non-critical scripts. Consider replacing heavy third-party widgets with lighter alternatives or load them only when needed.

What This Score Means

A score of 35 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 store has severe performance issues with a critically low score of 35/100. The biggest problem is excessive JavaScript execution, with the browser spending over 6 seconds processing and running scripts, which completely blocks user interactions and delays page loading. The site's Largest Contentful Paint takes an alarming 16.8 seconds, primarily due to heavy third-party scripts from YouTube, PayPal, and chat widgets that are unnecessarily slowing down the initial page load. Reducing JavaScript payloads, deferring non-critical scripts, and addressing render-blocking CSS files could potentially improve the score by 40+ points and dramatically enhance the shopping experience for customers.

Other Optimization Recommendations

Eliminate Render Blocking CSS

High Impact+18 points estimated

Why It Matters:

Render-blocking CSS delays First Contentful Paint by 1.05 seconds, preventing users from seeing content quickly.

How to Fix:

Inline critical CSS for above-the-fold content directly in your Shopify theme's liquid templates. Use Shopify's asset_url filter with media='print' onload='this.media="all"' to defer non-critical CSS files like section-footer.css and section-multicolumn.css. Minimize base.css by removing unused styles.

Optimize LCP Image Loading

High Impact+12 points estimated

Why It Matters:

The LCP image has lazy loading applied and lacks fetchpriority, delaying the largest contentful paint significantly.

How to Fix:

Remove loading='lazy' from the hero image in your image-with-text section. Add fetchpriority='high' to the LCP image element. Use Shopify's responsive image system with appropriate srcset values. Consider preloading the LCP image using <link rel='preload' as='image'> in your theme's head section.
