Remove Render Blocking CSS
High Impact+16 points estimated
Why It Matters
CSS files block initial page render for 1,550ms, significantly delaying FCP and LCP.
How to Fix
Inline critical above-the-fold CSS directly in theme.liquid head section. Load non-critical CSS asynchronously using media='print' onload technique. Optimize compiled_assets/styles.css by removing unused CSS rules (86% unused currently).

AI Performance Analysis
This Shopify store has poor performance with a score of 57/100, primarily due to excessive page redirects that are adding over 1 second of delay before the page even starts loading. The biggest issue is that users must wait through multiple redirects (likely from preview/theme switching), causing the First Contentful Paint to take 4.1 seconds and Largest Contentful Paint to reach 5.7 seconds - well beyond Google's recommended thresholds. Additionally, the site is loading 141KB of unused CSS and has render-blocking stylesheets that could be optimized. Fixing the redirect chain and streamlining the CSS delivery could potentially improve the performance score by 25-30 points and dramatically reduce load times for customers.
Other Optimization Recommendations
Eliminate Multiple Page Redirects
High Impact+18 points estimatedWhy It Matters:
Redirect chain wastes 1,070ms and delays both LCP and FCP by over 1 second.
How to Fix:
Update Shopify theme settings to remove preview parameters from URLs. Configure canonical URLs in theme.liquid to avoid _ab, _bt, and _fd parameters. Set up proper URL redirects in Shopify admin to eliminate the 2-hop redirect chain.
Optimize Swiper Library Usage
Medium Impact+8 points estimatedWhy It Matters:
Swiper.js causes 105ms of forced reflows and contains 55% unused JavaScript code.
How to Fix:
Replace heavy Swiper library with Shopify's native slider components where possible. If Swiper is required, load only needed modules and defer initialization until user interaction. Consider using CSS-only carousels for simple slider functionality.
