How to optimize capriprivateboattours.com
LCP is 7.0 seconds due to poor TTFB (870ms), resource delays (558ms), and render delays (1043ms) affecting the hero image.
Eliminate the redirect from root to /it path in Next.js routing. Optimize server response time by implementing proper caching headers. Add fetchpriority='high' and preload the hero image with <link rel='preload' as='image'>. Configure proper crossorigin attribute for Supabase preconnect.
A score of 56 falls in the "Needs Improvement" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

This Next.js/React site has poor performance with a score of 56/100, primarily due to an extremely slow Largest Contentful Paint of 7.0 seconds. The biggest issue is a redirect that's adding 760ms of delay before the page even starts loading, combined with a very slow server response time (870ms) and an unoptimized hero background image that could be compressed to save 26KB. The site is also loading 285KB of unused JavaScript from Google Analytics and other scripts that aren't needed immediately. Fixing the redirect, optimizing server response time, compressing the hero image, and deferring non-critical JavaScript could potentially improve the performance score by 25+ points and dramatically reduce load times for users.
Why It Matters:
Images are poorly compressed and oversized, wasting 47KB and delaying LCP by 600ms.
How to Fix:
Increase compression on the hero image to save 26KB. Implement Next.js responsive images with proper sizes prop for the tailored-for-you image. Use Next.js Image component optimization with quality=60 for non-critical images. Enable Supabase image transformations for automatic resizing.
Why It Matters:
CSS files are blocking First Contentful Paint by 400ms, delaying initial page rendering.
How to Fix:
Inline critical CSS for above-the-fold content in Next.js _document.js. Move non-critical CSS to load asynchronously using next/dynamic with ssr:false. Split large CSS chunks using Next.js CSS modules. Defer PostHog and tracking scripts until after page interactive.
Once your site is optimized, maintain that speed. Use DeployHQ for zero-downtime, automated deployments—so performance fixes and updates go live safely every time, without breaking your site.
