Loading speed depends on several factors. The highest-impact actions are:
- Optimize images: use modern formats (WebP or AVIF), compress without perceptible quality loss, implement lazy loading for below-the-fold images.
- Minify and compress: minify CSS, JavaScript and HTML. Enable Brotli or Gzip compression on the server.
- Use a CDN: distribute static content across servers close to the user. Cloudflare, Google Cloud CDN and CloudFront are popular options.
- Reduce third-party scripts: every tracking tag, widget or external plugin adds weight. Keep only the essentials.
- Efficient rendering: avoid render-blocking CSS and JavaScript. Load scripts with async or defer whenever possible.
