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.

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

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.

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.
