What is CDN and why do you need it in the first place?

Are you a proud owner of a website? Or do you run a blog? If your answers to these questions are yes, it means that you have one important goal - to offer content that the users who need it can reach quickly and safely.

None of us like to spend time and energy on pages that load slowly. Fortunately, technological advances also thought of this problem, and that is exactly how a CDN was created...

What is a CDN and why may you need one? CDN is a very important link when we talk about the delivery of content because it increases the response speed of the server (ie the loading of the site itself).

Did you know that CDN is actually one of the most important technologies on the Internet today? We live fast, we don't have enough time for everything we would like to see, research, or read... No one has the time or wants to wait minutes for a certain blog to load.

When we look at the statistics of sites that use CDN, we will very easily come to a conclusion about its effectiveness. First 10,000 sites that appear on Google search - half of them use CDN (48.3% to be exact!). Of course, that number is increasing daily, so it is possible to expect that these sites will use CDN in the proportion of an incredible 80% by 2022!

Don't worry, you're still not late to speed up your own site or blog. Yet, if you still think that the lack of technical knowledge makes it difficult for you to understand and use CDN, let us present everything you need to know in a simple manner.

A CDN, or Content Delivery Network, is actually a system of interconnected networks. Of course, all these networks are located in many locations around the world.

What happens when you start using the CDN service? Cached content is delivered by the mentioned servers, and travels faster to the user.

Let's start with this assumption - the user came to your site. Take for example that you have a WordPress blog. The user is there. He or she will be redirected to a specific location. That server can be your company's hosting, in the first place.

Where is your company's core data center located? We'll say it could be in Paris. Are all users being redirected to that master server? That would definitely mean a lot of traffic for just one hosting location, and it would slow down the entire process... 

For that very reason, CDN technology is posted and found all over the globe! This feature redirects users to their nearest server location, making it easier and faster to load the system - no more overloading the main hosting server.

Also, your cache content is stored on each of the CDN servers around the world (of course, if you visit it and use it). Therefore, which server is closest to you - to that server will CDN redirect you, resulting in faster loading of the website.

It is important to note (and we explained at the very beginning in the statistics section) that CDN has a very important impact on SEO and the positioning of your site on Google search engines. How? For the simple reason that it creates the optimal speed, and thus completes the user experience in an ideal way.

Page speed insight and CDN go hand in hand. We have already concluded that CDN prevents the site from crashing - no more inconveniences and annoyances.

It is also worth mentioning that CDN can provide better protection online, primarily against hacker attacks because it offers different types of user protection.

When everything we said comes together, it is very clear why you need a CDN for a site or blog.

Among other things, when you just remember the statistics related to CDN, it will be clear to you that this future is inevitable and that almost all site owners will use CDN technology within just a few years.

Are you ready to speed up and improve the positioning of your own site or blog?

We think you are!
