Defer Render-Blocking CSS

High Impact+6 points estimated

Why It Matters

CSS file is blocking initial render and delaying both LCP and FCP by 150ms.

How to Fix

Move the 0t0fvh_tzx82b.css file to load asynchronously using Next.js dynamic imports or rel='preload' with onload handler. Inline critical CSS for above-the-fold content directly in the HTML head. Use Next.js built-in CSS optimization features in next.config.js.

AI Performance Analysis

This Next.js/React website has good performance with a score of 89/100, but there's still room for improvement. The biggest issue is excessive unused JavaScript code that's delaying your Largest Contentful Paint by 750ms and wasting 159KB of bandwidth - nearly 96% of one JavaScript file isn't being used. Additionally, render-blocking CSS is slowing down initial page rendering by 150ms, and your logo image could be optimized to save 55KB by using modern formats like WebP and properly sizing it. Removing unused JavaScript code and deferring non-critical CSS would provide the most significant performance gains for your users.

Other Optimization Recommendations

Remove Unused JavaScript Code

High Impact+8 points estimated

Why It Matters:

159 KiB of unused JavaScript is delaying LCP by 750ms and blocking critical rendering.

How to Fix:

Use Next.js bundle analyzer to identify unused code in your chunks. Implement dynamic imports for non-critical components using React.lazy(). Configure webpack-bundle-analyzer to split chunks more efficiently and remove the 95% unused code in 06g244pea4~aa.js.

Optimize Logo Image Delivery

Medium Impact+4 points estimated

Why It Matters:

Logo image is oversized by 50KB and lacks proper dimensions, affecting both loading speed and CLS.

How to Fix:

Resize logo.png from 431x409 to actual display size of 177x168 pixels. Convert to WebP format to save 31KB. Add explicit width='177' height='168' attributes to the img tag to prevent layout shift during loading.
