Optimize Responsive Image Sizes

High Impact+15 points estimated

Why It Matters

Images are 133 KiB larger than needed for their display dimensions, delaying LCP by 150ms.

How to Fix

Configure Nuxt Image module with proper breakpoints: add 'sizes' prop matching your CSS breakpoints (378px mobile). Use '@nuxt/image' with 'fit=cover&f=webp' and implement multiple size variants. Set 'densities=[1,2]' for retina support.

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 website has poor performance with a score of 65/100, indicating significant user experience issues. The biggest problem is excessive unused JavaScript (223 KiB) that's blocking page interactivity and causing the Largest Contentful Paint to take a slow 6.8 seconds. The site is also serving oversized images that waste 133 KiB of bandwidth and could be optimized with responsive sizing. Removing unused JavaScript code and implementing proper image optimization could potentially improve load times by nearly a second and boost the performance score substantially.

Other Optimization Recommendations

Remove Unused JavaScript Code

High Impact+25 points estimated

Why It Matters:

223 KiB of unused JavaScript is delaying LCP by 900ms and blocking the main thread.

How to Fix:

Use Nuxt's tree-shaking by enabling 'experimental.payloadExtraction' and 'build.extractCSS'. Split your bundle with dynamic imports for routes and components. Remove unused libraries from your Nuxt modules array and audit third-party scripts.

Reduce Main Thread Blocking

Medium Impact+10 points estimated

Why It Matters:

270ms maximum FID indicates long tasks are blocking user interactions after page load.

How to Fix:

Wrap heavy computations in Vue's 'nextTick()' or use Web Workers for data processing. Implement code splitting with Nuxt's lazy loading for components. Use 'setTimeout' to break up long-running JavaScript tasks into smaller chunks.
