Best Practices for CDNs

Select a CDN with servers close to your target audience. Popular options include Cloudflare, Amazon CloudFront, and Fastly. Global coverage reduces latency for international visitors.
Configure your CDN to cache static assets like images, CSS, JavaScript, and fonts. This reduces load on your origin server and speeds up page delivery to users worldwide.
Most CDNs offer automatic compression. Enable Gzip or Brotli compression to reduce file sizes by 60-80%, dramatically improving load times for users far from your origin server.
Many CDNs offer automatic image optimisation, converting images to modern formats (WebP, AVIF) and resizing them based on device. This can significantly improve page speed scores.
