Fast websites feel premium. They also convert better. On mobile, speed is usually limited by images, JavaScript, and render-blocking resources.

Start with Core Web Vitals

  • LCP: the main content appears quickly
  • INP: taps feel responsive
  • CLS: layout doesn’t jump around

Images: the biggest lever

  • Serve appropriately sized images (don’t ship 1600px for a 360px card)
  • Use modern formats when possible
  • Lazy-load below-the-fold images

Reduce JS and CSS work

  • Ship only what you use
  • Avoid heavy libraries for small UI needs
  • Defer non-critical scripts

Caching and CDN basics

  • Cache images and static assets aggressively
  • Use a CDN for predictable latency across India
