What is a CDN and does your website need one? In this article, I will explain what a CDN is and how it affects your site's stats and search engine rankings.
With a CDN, you can significantly improve your site's Google rankings as it improves your site's loading speed. Slow loading speed is the main reason why users leave the site.
What is CDN
CDN (Content Delivery Network) is a geographically distributed network infrastructure that provides fast delivery of content to users of web services and sites. The servers included in the CDN are geographically located in such a way as to minimize the response time for users of the site / service.
The essence of a CDN is to distribute servers to different geographic locations as the further the user is from the original server, the longer the “original” response time.
CDN hosting is a server that caches part of the content or the entire page.
A bit of history
CDN providers began to appear in the late 1990s. As early as 2004, more than 3000 companies were using CDNs; total content delivery costs were up to $ 20 million per month.
What is a CDN for?
- CDN helps to minimize response time for website / service users.
- CDN also helps to reduce the risk of losing access to content due to a fall of the main server. The content will be available all the time while you restore the main server to work.
- CDN helps offload the server and alternates loading between static and dynamic content. Different types of content create a double load on the server. Static content uses RAM, while dynamic content depends on network speed.
- CDNs are also actively used to distribute streaming content.
How to know if you need a CDN

How to choose the right CDN provider?
