Fix Hero Section Layout Shifts
High Impact+20 points estimated
Why It Matters
The main hero section causes 0.288 CLS score due to content shifting during load, representing 95% of total layout shift issues.
How to Fix
Add explicit width and height attributes to all images in the hero section. Use CSS aspect-ratio or min-height to reserve space for dynamic content. Implement Next.js Image component with priority={true} for above-the-fold images to prevent shifts.

AI Performance Analysis
This Next.js site has severe performance issues with a poor score of 41/100. The biggest problem is excessive JavaScript blocking the main thread for over 3 seconds, causing the page to take nearly 20 seconds to become fully interactive. The site loads 399KB of unused JavaScript from Google Analytics and other third-party scripts, while also suffering from major layout shifts (0.302 CLS score) that make content jump around as it loads. Reducing JavaScript payloads, removing unused code, and fixing layout shifts by adding proper image dimensions could dramatically improve load times and user experience.
Other Optimization Recommendations

High Impact+25 points estimatedWhy It Matters:
399 KiB of unused JavaScript and 3.3s of main thread blocking time severely impact Time to Interactive (19.9s) and user experience.
How to Fix:
Implement Next.js dynamic imports for non-critical components using next/dynamic. Remove duplicate Google Tag Manager instances (3 similar scripts loading). Use webpack-bundle-analyzer to identify and eliminate unused code from your Next.js bundles.

Medium Impact+8 points estimatedWhy It Matters:
Font display issues cause 30ms delay to First Contentful Paint and contribute to layout shifts during text rendering.
How to Fix:
Add font-display: swap to your custom Aprova-Black font CSS declaration. Implement font metric overrides in your Next.js _document.js to match fallback fonts. Preload critical fonts using Next.js Head component with rel='preload'.
