A Content Delivery Network (CDN) is a network of distributed servers whose main goal is to accelerate and optimise the delivery of web content and services. This is done by bringing content closer to end users, usually by storing copies of web resources such as text, images and videos on multiple geographically distributed servers. When a user accesses a particular piece of content, the CDN forwards the request to the nearest server to minimise delays and latency.

By using CDNs, companies can not only improve the performance of their website, but also increase reliability and security. For example, CDNs can intelligently distribute traffic to better handle peak loads and even fend off DDoS attacks. In this way, CDNs play a crucial role in ensuring a high quality of service, which in turn improves the user experience and ultimately conversion rates.

For marketing experts, the use of a CDN offers the opportunity to organise multimedia campaigns more smoothly and achieve global reach without compromising performance. In addition, advanced analyses and monitoring functions of CDNs enable a deeper insight into user behaviour. This provides valuable data that can be used to optimise marketing strategies. In an increasingly globalised and digitalised world, a CDN is therefore an indispensable tool in the modern marketing toolkit.
