Let’s talk about something that’s important for almost every single website: speed optimisation. To discuss this, we need to mention a key player: the CDN. A CDN plays an important role in optimising website speed. However, many people are unaware of how a content delivery network (CDN) affects speed optimisation.

What is a CDN?

Let’s get to the point and define the concept of a CDN. A CDN is a network of locations around the world, which we will henceforth refer to as PoPs (Points of Presence). Based on customisable parameters, PoPs distribute content locally from the servers and cache those files that do not require constant updating. This system enables the caching of a website’s static content, such as HTML, CSS, JavaScript, image and video files – all of which remain the same for every user. By making these static files available via a CDN with numerous servers located in various parts of the world, the content is delivered to the end user from the server closest to their location. Shortening the distance the data has to travel reduces bandwidth consumption and latency, and significantly improves speed.

Using a CDN improves the user experience by speeding up the delivery of web content to the end user:

• The route taken by the data is better; it reaches the visitor sooner
• The servers used to deliver the content are optimised to handle traffic more efficiently
• These servers are capable of handling large volumes of traffic at certain times

Tips for further optimisation

As well as a CDN, there are a number of other benefits and features that can be used to improve website optimisation and make it faster for search engines.

• Optimising images and videos: This improves server performance by reducing the size of multimedia content delivered to the end user. Use an image optimisation system.
• Stabilising your website: This minimises risks during peak traffic periods.
• Website protection: Acting as the first line of defence at the security layer (user requests are handled by our servers without ever reaching the original servers). Look for protection against DDoS attacks, for example.
• Reduce server load: As content is distributed across multiple servers, the load is handled simultaneously from the caches. This ensures that your own bandwidth is not wasted or overused, and that the server does not crash, whilst also responding more quickly. And if your server were to go down for any reason, your web content would still be displayed, as this content is cached in Edge Services.

That is why using a CDN and the other services mentioned earlier improves the speed and quality of content delivered to the end user, and contributes to your SEO strategy (yes, a CDN speeds up web page loading, which improves your search engine ranking). This therefore has an impact on a website’s search engine ranking. What are you waiting for to improve your search engine ranking and move up the rankings?
