I really need help with performance:

  • Optimized the images.
  • Added defer to all third party scripts (like GTM).
  • Lazy loading applied to all images, except the first image, which is included in FCP.
  • Cleared unused CSS and animations.
  • Converted all images to WebP format.
  • Minify HTML, CSS, and JS

Which areas should I work on next? Please help me.
