// Performance
A network of servers distributed globally that serves static assets (images, scripts, fonts) from a location near the user. Reduces TTFB and improves load speed for international visitors. Most modern hosting platforms include a CDN by default.
Why it matters: CDN (Content Delivery Network) is one of the performance signals that shapes how search engines, AI tools, and real visitors experience your website. Getting it right removes friction, protects your rankings, and makes every other optimization work harder. Auditing it regularly is the fastest way to catch regressions before they cost you traffic or conversions.
