Defer Non-Critical JavaScript Loading
High Impact+15 points estimated
Why It Matters
Unused JavaScript is costing 600ms in LCP delay and consuming 288 KiB of bandwidth.
How to Fix
Move Google Tag Manager and analytics scripts to load after page interaction using Next.js Script component with strategy='afterInteractive'. Implement code splitting for unused portions of your JavaScript bundles. Use dynamic imports for non-critical components to reduce initial bundle size.

AI Performance Analysis
This Next.js boat tour website has below-average performance with a score of 73/100, struggling with slow loading times that hurt user experience. The biggest problem is an extremely slow Largest Contentful Paint of 6.3 seconds, primarily caused by large video files (over 5MB for the hero video) and render-blocking CSS files that delay the initial page display by 440ms. The site is also loading nearly 300KB of unused JavaScript from Google Analytics and Tag Manager scripts that could be deferred, while inefficient caching settings are missing opportunities to speed up repeat visits. Optimizing video delivery, deferring non-critical JavaScript, and implementing proper caching could easily improve the performance score by 15-20 points and dramatically reduce loading times.
Other Optimization Recommendations
Optimize Hero Video and Images
High Impact+18 points estimatedWhy It Matters:
Large video files (5.7MB + 1.5MB) and unoptimized images are causing slow LCP of 6.3 seconds.
How to Fix:
Compress hero videos using tools like HandBrake with H.264 codec targeting 1-2MB max size. Replace video poster with optimized WebP at higher compression. Use Next.js Image component with priority prop for above-the-fold images and implement responsive sizing.
Implement Efficient Browser Caching
Medium Impact+8 points estimatedWhy It Matters:
Poor cache policies are wasting 192 KiB on repeat visits and delaying LCP by 1050ms.
How to Fix:
Configure your Supabase storage bucket with longer cache headers (max-age=31536000 for static assets). Add cache-busting query parameters for updated content. Set up Next.js static optimization in next.config.js with proper headers for immutable assets.
