Content Delivery Network (CDN)

A Content Delivery Network (CDN) is a network of servers spread across the whole world that stores copies of your website files closer to your visitors. Instead of fetching every file from one central server, the visitor gets the data from a server nearby, which greatly shortens your load time.

How does a CDN work?

When someone visits your site, static files such as images, stylesheets and scripts are delivered from the nearest server, the so-called edge node. A visitor from Antwerp thus gets data from a European data center instead of from a server on the other side of the world. Less distance means less delay. The CDN also absorbs peaks in traffic and keeps your site standing when many people visit at once.

What does a CDN deliver?

The main gain is speed. Faster delivery improves your page speed and contributes directly to better Core Web Vitals, in particular your LCP, because your largest elements arrive faster. In combination with smart lazy loading you get the most out of both. Most CDNs also deliver content over a secure connection, which works well with your SSL certificate. They also often offer protection against attacks and relieve your main server.

Why this matters for your growth

At Customer Impact we build sites that are not only beautiful, but that perform where it counts. A CDN is invisible to the visitor, but noticeable in every second you save. In B2B, where decision-makers often visit from different locations and networks, a fast, reliable site ensures your proposition always comes into view smoothly. Speed that does not cost you customers is speed that works.
