Advanced Website Performance Analysis

• Unoptimized Images
  15 images could be optimized, saving ~1.8MB of page weight. This is causing slow loading times.
  Optimization Solution:

  • Compress images using tools like TinyPNG or Squoosh
  • Convert images to modern formats like WebP
  • Implement responsive images with srcset attribute
  • Set explicit width and height for images
  • Use lazy loading for below-the-fold images
• Render-Blocking Resources
  5 CSS files and 3 JavaScript files delay page rendering by 1.2 seconds.
  Optimization Solution:

  • Minify and combine CSS/JS files
  • Defer non-critical JavaScript
  • Load CSS asynchronously using preload
  • Remove unused CSS with PurgeCSS
  • Implement code splitting for JavaScript
• No Caching Policy
  Static resources are not cached, increasing load times for repeat visitors by 40%.
  Optimization Solution:

  • Set cache-control headers for static assets
  • Implement browser caching with max-age directive
  • Use service workers for advanced caching
  • Leverage CDN caching for global performance
  • Set proper ETag headers for cache validation
