Eliminate Unused JavaScript Code

High Impact+18 points estimated

Why It Matters

248KB of unused JavaScript is blocking rendering and adding 1.2 seconds to LCP.

How to Fix

Use Nuxt's tree-shaking by importing only needed functions instead of entire libraries. Enable code splitting with dynamic imports for route-specific components. Configure Nuxt's vite.build.rollupOptions to exclude unused dependencies from the main bundle.

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, indicating significant room for improvement. The biggest problem is an extremely slow Largest Contentful Paint of 11.4 seconds, primarily caused by an oversized product image (608KB) that could be reduced by over 600KB through proper compression and responsive sizing. The site is also loading 248KB of unused JavaScript and 60KB of unused CSS, which could save 1.2 seconds in load time if removed. Addressing the image optimization alone could improve LCP by 2.4 seconds, while cleaning up the unused code and implementing proper caching would provide substantial additional performance gains.

Other Optimization Recommendations

Optimize LCP Image Delivery

High Impact+25 points estimated

Why It Matters:

The product image is causing an 11.4s LCP delay and wasting 606KB due to poor optimization and discovery.

How to Fix:

Convert the product image to WebP format and resize from 800x450 to 158x89 for the displayed size. Add fetchpriority='high' to the LCP image element. Use Nuxt's <NuxtImg> component with format='webp' and sizes prop for automatic optimization.

Fix Render Blocking Resources

Medium Impact+12 points estimated

Why It Matters:

Multiple CSS files are blocking first paint and delaying FCP by 950ms.

How to Fix:

Inline critical CSS for above-the-fold content using Nuxt's css configuration. Use async loading for non-critical CSS files like ContinuousDates and Textarea components. Implement Nuxt's experimental.inlineSSRStyles to reduce render-blocking requests.
