Eliminate Render Blocking CSS
Medium Impact+8 points estimated
Why It Matters
Two CSS files are blocking initial render, adding 150ms delay to First Contentful Paint.
How to Fix
Use Next.js built-in CSS optimization by importing critical styles in _app.js. Move non-critical styles to load asynchronously using next/dynamic with ssr: false. Inline critical CSS for above-the-fold content in the document head.

AI Performance Analysis
This Next.js site has poor performance with a score of 63/100, indicating significant issues that need attention. The biggest problem is extremely slow content loading, with the Largest Contentful Paint taking 7.9 seconds - far exceeding Google's recommended 2.5 seconds. The main culprits are oversized images that are much larger than their display dimensions (wasting 317 KiB), unused JavaScript from Google Analytics and tracking scripts (wasting 116 KiB), and render-blocking CSS files that delay initial page rendering. Optimizing image sizes, removing unused JavaScript code, and deferring non-critical resources could dramatically improve load times and boost the performance score by 25+ points.
Other Optimization Recommendations

High Impact+15 points estimatedWhy It Matters:
The LCP image has 1.9 seconds of render delay and poor compression, directly impacting the 7.9s LCP score.
How to Fix:
Increase compression on the hero image (4210-900x600.webp) to save 54KB. Move the image to a CDN with better cache headers. Use Next.js Image component with priority prop and optimize=true for automatic optimization.
Remove Unused JavaScript Code
High Impact+12 points estimatedWhy It Matters:
116KB of unused JavaScript from Google Tag Manager scripts delays LCP by 350ms and FCP by 300ms.
How to Fix:
Implement Google Tag Manager with Next.js gtag configuration to load only required tracking. Use next/script component with strategy='afterInteractive' for non-critical analytics. Remove unused tracking pixels and defer secondary scripts.
