Reduce Main Thread Blocking
High Impact+20 points estimated
Why It Matters
JavaScript execution blocks the main thread for 3.5 seconds, preventing user interactions and increasing TBT to 450ms.
How to Fix
Update your Next.js build configuration to target modern browsers and remove legacy polyfills (saves 14KB). Split large JavaScript chunks using dynamic imports for non-critical features. Move third-party scripts like Clarity analytics to web workers or defer until after page interactive.

AI Performance Analysis
This Next.js/Shopify site has poor performance with a score of 65/100, particularly struggling with slow loading times. The biggest problem is excessive JavaScript execution taking 3.5 seconds of main thread work, which is blocking user interactions and causing the page to become fully interactive only after 8.2 seconds. The site is also serving oversized product images that are 4x larger than needed, wasting over 2MB of bandwidth, and these images lack proper dimensions causing layout shifts. Optimizing JavaScript payloads, properly sizing images with responsive formats, and adding explicit width/height attributes to images could dramatically improve loading speed and user experience.
Other Optimization Recommendations
Optimize Oversized Product Images
High Impact+25 points estimatedWhy It Matters:
Product images are 4x larger than needed, wasting 2.4MB and delaying LCP by 5.8 seconds.
How to Fix:
Configure Shopify's responsive image settings to serve appropriately sized images. Update Next.js Image components to use srcSet with multiple breakpoints (274w, 548w, 822w). Enable automatic WebP conversion in your CDN settings. Add priority loading to above-the-fold product images.
Eliminate Render Blocking CSS
Medium Impact+8 points estimatedWhy It Matters:
Critical CSS files delay first paint by 160ms and prevent users from seeing content immediately.
How to Fix:
Inline critical CSS directly in your Next.js pages using styled-jsx or CSS-in-JS. Move non-critical stylesheets to load asynchronously using Next.js dynamic imports. Configure your build process to automatically extract and inline above-the-fold CSS.
