Optimize Unused JavaScript Bundle

High Impact+20 points estimated

Why It Matters

358KB of unused JavaScript is adding 2.4 seconds to LCP and blocking main thread execution.

How to Fix

Enable Nuxt's tree-shaking by setting 'build.extractCSS: true' in nuxt.config.js. Implement dynamic imports for heavy components using Vue's defineAsyncComponent(). Move Google Analytics to a separate worker thread or use Nuxt's @nuxtjs/gtm module for better performance. Split vendor bundles using Nuxt's build.splitChunks configuration.

What This Score Means

A score of 50 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 Nuxt/Vue website has poor performance with a score of 50/100, indicating significant issues that hurt user experience. The biggest problem is render-blocking CSS files that are preventing the page from loading quickly, causing an extremely slow Largest Contentful Paint of 11.6 seconds and delaying first content visibility to 7.8 seconds. The site is also loading 358 KB of unused JavaScript and serving oversized images with poor caching, which compounds the loading delays. Fixing the render-blocking resources alone could improve loading times by over 1 second, while optimizing unused code and implementing proper image sizing could dramatically boost the performance score.

Other Optimization Recommendations

Eliminate Render-Blocking CSS

High Impact+25 points estimated

Why It Matters:

Critical CSS files are blocking initial render for 1.2 seconds, severely delaying both FCP and LCP.

How to Fix:

Inline critical CSS in your Nuxt config using the 'css' property for above-the-fold styles. Use Nuxt's built-in code splitting by moving non-critical styles to component-level <style> blocks. Configure the build process to defer loading of unused CSS files like cart.y9TWX9T0.css and configure.CUv6LAjM.css which are 100% unused.

Implement Responsive Image Optimization

Medium Impact+8 points estimated

Why It Matters:

The hero image is oversized by 41KB and has insufficient caching, contributing to poor LCP performance.

How to Fix:

Use Nuxt's @nuxt/image module to automatically generate responsive images with proper srcset. Configure image caching headers to extend beyond 60 seconds - set cache-control to 'public, max-age=31536000' for static images. Optimize the hero image dimensions to match its display size (364x364 instead of 700x700) in your image processing pipeline.
