Why It Matters
Multiple redirects add 760ms delay before any content can load, significantly hurting all Core Web Vitals.
How to Fix
Update your domain configuration to serve https://harlowe.eu/en-eu directly without redirecting from https://harlowe.eu/. Configure your Shopify domain settings or CDN to point directly to the final URL. Update all internal links and canonical URLs to use the final destination.

AI Performance Analysis
This Shopify/React site has poor performance with a score of 53/100. The biggest problem is render-blocking CSS files that are delaying page loading by 600ms, combined with a slow initial server response that adds another 560ms of delay. The site is also experiencing forced reflows from JavaScript that query page geometry, causing layout thrashing and poor user experience. Fixing the render-blocking resources by deferring or inlining critical CSS, optimizing server response time, and addressing the JavaScript performance issues could improve loading speeds by over 1 second and significantly boost the performance score.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+12 points estimatedWhy It Matters:
Critical CSS files are blocking page render by 600ms, directly delaying both FCP and LCP.
How to Fix:
In your Shopify theme, inline critical CSS for above-the-fold content directly in the <head>. Use Shopify's liquid {% style %} tags to inline essential styles. Defer non-critical CSS like SanityModules-B_l4pjL9.css and root-BWvG-ZxC.css using media='print' onload='this.media="all"' technique.
Optimize JavaScript Bundle Loading
Medium Impact+8 points estimatedWhy It Matters:
Heavy JavaScript execution (2.0s) creates main thread blocking and forced reflows totaling 147ms.
How to Fix:
Split your large components-CBmdcfh3.js bundle using React.lazy() and Suspense for code splitting. Implement dynamic imports for non-critical Shopify app components. Use React.memo() to prevent unnecessary re-renders that trigger layout recalculations in your product recommendation components.
