How to optimize hexbytes.in
94% of your CSS (107KB) and 198KB of JavaScript are unused, causing 1.2 second delay in FCP and LCP.
Use Next.js dynamic imports to code-split unused page components like about-43053e657f5c6c8c.js. Remove unused Tailwind CSS classes with PurgeCSS configuration in next.config.js. Defer third-party scripts like Google Analytics and Facebook Pixel until after page load.
A score of 37 falls in the "Poor" 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.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

Measures visual stability - how much content shifts during page load
This Next.js/React site has poor performance with a score of 37/100, indicating significant user experience issues. The biggest problem is massive image optimization failures - three testimonial images are consuming over 4MB while displaying at tiny 140x80 pixel sizes, creating enormous waste and severely impacting load times. Your Largest Contentful Paint takes a painful 9.5 seconds, and users can't interact with the page for over 14 seconds due to excessive JavaScript blocking the main thread. Converting images to modern formats (WebP/AVIF), properly sizing them for display dimensions, and reducing unused JavaScript could easily improve your score by 30+ points and dramatically speed up the site.
Why It Matters:
The redirect from hexbytes.in to www.hexbytes.in delays LCP by 800ms, while oversized testimonial images waste 4MB of bandwidth.
How to Fix:
Update all internal links to use https://www.hexbytes.in directly to eliminate the redirect. Convert testimonial images to WebP format and resize from 800x800 to 140x140 using Next.js Image component with proper width/height props. Add fetchpriority='high' to the LCP image.
Why It Matters:
Legacy JavaScript polyfills and forced reflows block the main thread for 435ms, degrading user interaction responsiveness.
How to Fix:
Update Next.js target to 'es2020' in next.config.js to remove unnecessary polyfills for modern browsers. Optimize React components causing forced reflows by batching DOM reads/writes and using CSS transforms instead of layout-triggering properties. Consider removing Facebook Pixel or loading it asynchronously.
