Does my website need a CDN?
In short and in plain language
A network of servers in many countries can deliver files close to each visitor. This pays off when your visitors are spread far apart.
Do most visitors come from Germany, with your server here? Then it adds little. Caching and smaller images usually help more.
For shops with customers all over the world, it can cut load times a lot.
We do not suggest it by default. In our analysis we check if it is worth it for you.
A Content Delivery Network is worthwhile above all when your visitors are geographically dispersed. The CDN keeps static resources like images, CSS and JavaScript on servers in many countries and serves them from the nearest location. The effect is a shorter distance and therefore lower latency, which is especially noticeable for the LCP resource.
For a regional website with predominantly German visitors and a server located in Germany, the added benefit is limited, here caching and image optimization usually achieve more. For international websites or shops with a worldwide customer base, a CDN can considerably cut load times for distant visitors. So we do not recommend a CDN by default but assess in the performance analysis whether your visitor distribution justifies it.
