Remove Unused JavaScript Bundles

High Impact+20 points estimated

Why It Matters

725 KiB of unused JavaScript is wasting 3.6 seconds of load time and blocking the main thread.

How to Fix

Use Next.js dynamic imports with next/dynamic to code-split large vendor chunks. Analyze your bundle with @next/bundle-analyzer to identify unused dependencies. Configure tree-shaking in your webpack config and remove unused polyfills from your target browser configuration.

What This Score Means

A score of 29 falls in the "Poor" 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 Next.js site has severe performance issues with a score of only 29/100. The biggest problems are massive amounts of unused JavaScript (725 KiB wasted) and render-blocking CSS files that delay initial page rendering by nearly 2 seconds, causing the main content to take a devastating 14 seconds to appear. The site also suffers from significant layout shifts (0.26 CLS score) due to unsized images and experiences over 1 second of blocking time from excessive JavaScript execution. Removing unused code, optimizing CSS delivery, and properly sizing images could dramatically improve the score by 40+ points and transform the user experience from frustratingly slow to acceptably fast.

Other Optimization Recommendations

Eliminate Render-Blocking CSS Resources

High Impact+25 points estimated

Why It Matters:

CSS files are blocking page rendering for 1.9 seconds, severely delaying LCP by preventing content from appearing.

How to Fix:

In your Next.js app, split critical CSS using the 'critical' package and inline it in the <head>. Move non-critical CSS to load asynchronously using next/dynamic or implement CSS code splitting. Consider using Next.js built-in CSS optimization by ensuring proper import order.

Fix Layout Shifts from Images

Medium Impact+8 points estimated

Why It Matters:

Unsized images are causing 0.258 CLS score, making content jump and hurting user experience.

How to Fix:

Add explicit width and height props to all Next.js Image components. Use the 'fill' prop with proper container sizing for responsive images. Implement placeholder='blur' with blurDataURL for smooth loading transitions to prevent layout shifts.
