Fix Critical Resource Caching

Medium Impact+12 points estimated

Why It Matters

Missing cache headers force users to re-download 222 KiB on every visit, slowing repeat page loads.

How to Fix

Configure your CDN/server to set long-term cache headers (1 year) for static assets like images and JavaScript bundles. Set shorter cache (20 minutes) for Facebook scripts. Use Nuxt's built-in asset fingerprinting to enable safe long-term caching.

What This Score Means

A score of 67 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 67/100, primarily due to an extremely slow Largest Contentful Paint of 7.7 seconds. The biggest culprit is excessive unused JavaScript (211 KiB worth) that's blocking the page from loading quickly, combined with unoptimized images that could be compressed and resized to save 152 KiB. The site is also suffering from inefficient caching and render-blocking CSS files that delay the initial paint by 3.6 seconds. Removing unused JavaScript, optimizing images, and implementing proper caching could potentially improve the performance score by 25+ points and dramatically enhance user experience.

Other Optimization Recommendations

Remove Unused JavaScript Code

High Impact+25 points estimated

Why It Matters:

Eliminating 211 KiB of unused JavaScript can improve LCP by 900ms and reduce blocking time significantly.

How to Fix:

Use Nuxt's tree-shaking by enabling 'build.analyze' to identify unused code. Split the large CHSsAhP0.js bundle using dynamic imports for non-critical components. Consider lazy-loading Facebook Pixel or moving it to a web worker to reduce main thread blocking.

Optimize Image Delivery Pipeline

High Impact+20 points estimated

Why It Matters:

Poor image optimization is causing 152 KiB waste and 900ms LCP delay for critical product images.

How to Fix:

Implement responsive images using Nuxt Image module with multiple sizes for the product image (currently 700x700 displayed as 158x158). Enable automatic WebP/AVIF conversion and compression. Add proper srcset attributes to serve appropriately sized images based on device.
