Optimize Image Delivery and Sizing
Medium Impact+12 points estimated
Why It Matters
Oversized images waste 2MB of bandwidth and slow down page loading unnecessarily.
How to Fix
Use Shopify's responsive image system with srcset attributes and appropriate width parameters. Replace your 3336px brand images with properly sized versions (max 800px for mobile). Implement lazy loading using Shopify's native loading='lazy' or intersection observer for below-fold images.

What This Score Means
A score of 55 falls in the "Needs Improvement" 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 poor performance with a score of 55/100. The biggest problem is extremely slow page loading caused by multiple page redirects and render-blocking CSS files, which together delay your First Contentful Paint and Largest Contentful Paint by over 2 seconds. The site also suffers from excessive main-thread work (2.8 seconds) and oversized images that waste 2MB of bandwidth. Fixing the redirect chain, deferring non-critical CSS, and properly sizing images could improve your score by 30+ points and dramatically reduce the current 31.5-second Largest Contentful Paint time.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+25 points estimatedWhy It Matters:
Render-blocking CSS delays LCP and FCP by 1,590ms, preventing users from seeing content quickly.
How to Fix:
In your Shopify theme, inline critical above-the-fold CSS directly in the <head> section. Use the 'media' attribute to load non-critical CSS asynchronously. Consider splitting your 46KB styles.css file and deferring non-essential styles using preload with onload fallback.
Remove Unused CSS and JavaScript
High Impact+20 points estimatedWhy It Matters:
Unused code adds 285KB of unnecessary payload, increasing parse time and blocking rendering.
How to Fix:
Use Shopify's liquid conditionals to load CSS/JS only on relevant pages. Remove or replace the Swiper library (55% unused) with a lighter alternative. Audit and eliminate unused Shopify preview bar assets in production. Use code splitting to deliver only necessary JavaScript per page.
