Why It Matters
Unused JavaScript totals 349 KiB and blocks the main thread for 3.5 seconds, severely impacting TBT.
How to Fix
Implement dynamic imports for non-critical components in Next.js using next/dynamic. Use webpack-bundle-analyzer to identify unused code. Enable tree shaking and code splitting for route-based chunks.

AI Performance Analysis
This Next.js/React site has severe performance issues with a critically low score of 29/100. The biggest problem is an extremely slow Largest Contentful Paint of 23.2 seconds, caused by lazy-loaded images that should be prioritized, combined with massive JavaScript execution taking 3.5 seconds to process. The site is loading nearly 4MB of data including unused CSS (71KB) and JavaScript (349KB), while render-blocking stylesheets delay the initial page display by 1.4 seconds. Removing lazy loading from above-the-fold images, reducing unused code, and optimizing the JavaScript bundle size could dramatically improve performance and user experience.
Other Optimization Recommendations
Optimize LCP Image Loading
High Impact+25 points estimatedWhy It Matters:
The LCP image has lazy loading enabled and lacks priority hints, causing a 23.2s LCP delay.
How to Fix:
Remove loading='lazy' from the hero image and add fetchpriority='high'. Use Next.js Image component with priority={true} prop. Preload the LCP image URL in the document head using <link rel='preload' as='image'>.
Eliminate Render-Blocking CSS
High Impact+18 points estimatedWhy It Matters:
Multiple CSS files block first paint for 1.4 seconds, delaying FCP significantly.
How to Fix:
Inline critical CSS for above-the-fold content in the Next.js _document.js file. Use next-optimized-css to automatically split and defer non-critical stylesheets. Combine smaller CSS files into single bundles.
