Eliminate Unused JavaScript Code
High Impact+12 points estimated
Why It Matters
282 KiB of unused JavaScript is blocking page load and delaying LCP by 600ms.
How to Fix
Use Next.js bundle analyzer to identify unused code in your chunks. Remove or defer Google Tag Manager and analytics scripts using next/script with strategy='afterInteractive'. Split large bundles and implement dynamic imports for non-critical components using next/dynamic.

AI Performance Analysis
This Next.js site has moderate performance issues with a score of 78/100. The biggest problem is excessive unused JavaScript from Google Analytics and other scripts, which is wasting 282 KB and creating a sluggish 9.3-second Time to Interactive. The site is also being held back by render-blocking CSS files and inefficient image compression that could save an additional 25 KB. Removing unused JavaScript code, optimizing image compression, and implementing proper caching strategies could improve the score by 15+ points and significantly speed up the user experience.
Other Optimization Recommendations
Remove Render Blocking CSS
High Impact+8 points estimatedWhy It Matters:
Critical CSS is blocking initial page render and delaying LCP by 200ms.
How to Fix:
In your Next.js app, inline critical CSS directly in the document head using styled-jsx or CSS-in-JS. Move non-critical styles to load asynchronously using next/dynamic or loadCSS. Consider code-splitting your CSS bundle to only load styles needed for above-the-fold content.
Optimize Image Compression Settings
Medium Impact+5 points estimatedWhy It Matters:
Poor image compression is wasting 25 KiB and impacting LCP performance by 200ms.
How to Fix:
Increase compression quality in your Netlify image transform URLs by lowering the 'q' parameter from 80 to 65-70. For the hero background image, consider using a more aggressive compression or switching to AVIF format. Use Next.js Image component with optimized quality settings for automatic compression.
