Optimize Above-fold Video Loading
High Impact+18 points estimated
Why It Matters
The LCP video has 4.7 seconds of element render delay and lacks fetchpriority optimization.
How to Fix
Add fetchpriority='high' to the video element that serves as LCP. Preload the video poster image using <link rel='preload' as='image' href='/images/video-placeholder.webp'>. Consider using a lighter video format or optimized poster image for faster initial render.

AI Performance Analysis
This Next.js website has poor performance with a score of 56/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking over 3 seconds, which is blocking the main thread and preventing user interactions - your page doesn't become interactive until 10.6 seconds, which is extremely slow. The site is also serving an unnecessarily large 12MB video file and oversized images that aren't properly optimized for mobile devices. Reducing JavaScript bundle sizes, optimizing the video file, and implementing responsive images could improve your score by 30+ points and dramatically speed up load times for your users.
Other Optimization Recommendations
Reduce JavaScript Bundle Size
High Impact+15 points estimatedWhy It Matters:
182 KiB of unused JavaScript is delaying LCP by 950ms and blocking main thread for 1.6 seconds.
How to Fix:
Enable Next.js code splitting by using dynamic imports for non-critical components. Remove unused polyfills by updating your Babel config to target modern browsers only. Defer third-party scripts (Facebook Pixel, Google Analytics) using Next.js Script component with strategy='afterInteractive'.
Implement Proper Image Optimization
Medium Impact+8 points estimatedWhy It Matters:
Images are oversized by 131 KiB and missing responsive optimization, impacting LCP by 200ms.
How to Fix:
Configure Next.js Image component with proper responsive breakpoints matching your CSS. Use quality={75} instead of quality={100} for blog images. Add sizes='(max-width: 575px) 545px, (max-width: 992px) 975px, 100vw' with correct breakpoint values that match your actual layout.
