Medium Impact+12 points estimated
Why It Matters
Critical resources have no cache headers, forcing users to re-download 600KB on every visit.
How to Fix
Configure Nuxt's nitro.storage with appropriate cache headers for static assets. Set Cache-Control headers for images (1 year) and CSS/JS (1 month). Use Nuxt's built-in static asset optimization by placing images in the public directory.

What This Score Means
A score of 65 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 site has poor performance with a score of 65/100, primarily due to extremely slow loading times that hurt user experience. The biggest problem is the Largest Contentful Paint taking 10.5 seconds, largely caused by an oversized 608KB product image that could be reduced by over 600KB through modern formats like WebP and proper sizing. The site is also loading 175KB of unused JavaScript code and has render-blocking CSS files that delay the initial page display by nearly 300ms. Fixing the image optimization alone could improve loading speed by 3.5+ seconds and significantly boost the performance score.
Other Optimization Recommendations
Optimize Product Image Delivery
High Impact+25 points estimatedWhy It Matters:
The main product image (608KB) is severely oversized and delays LCP by 3.55 seconds.
How to Fix:
Use Nuxt Image module with responsive breakpoints and WebP format. Add srcset with appropriate sizes for mobile/desktop. Implement server-side image optimization or use a CDN like Cloudinary with Nuxt's @nuxtjs/cloudinary module.
Remove Unused JavaScript Code
High Impact+18 points estimatedWhy It Matters:
175KB of unused JavaScript delays LCP by 750ms and blocks the main thread unnecessarily.
How to Fix:
Enable Nuxt's tree-shaking by setting nitro.experimental.wasm = true. Use dynamic imports for heavy components with defineAsyncComponent(). Run nuxt analyze to identify unused dependencies and remove them from your bundle.
