What Are the Advantages of Content Delivery Networks (CDNs)?


Have you just launched your website and are looking into ways of improving it? Are you looking for some techniques which will bring positive SEO results and more satisfied and organic users? If your purpose is to provide the best possible online experience to your users, you’re at the right place. We’ll help you understand why a CDN is the solution you’ve been looking for. 

What Is a CDN and How Does It Work?

A Content Delivery Network (CDN) is a network of connections between proxy servers and an origin server. The edge servers are physically located all over the world in order to distribute the content to your global users faster, improving their overall user experience. CDNs use this interconnected system to duplicate and cache the content of the origin server and deliver it to the users who are closest to them geographically. The sole purpose of a CDN is to make high-performance content available to its users. 


CDNs mostly serve for distributing the following web content: 


  • web objects, including text, script, and graphics; 
  • downloadable objects – documents, software, and media files; 
  • applications – e-commerce and portals; 
  • on-demand streaming media; 
  • real-time streaming data; 
  • social networks, etc. 


So, when a user requests a webpage on the web browser, a video, or they want to download some file, the server which is closest to them will deliver the content fast. 


Many companies, especially those in the media industry, have seen amazing results with CDNs. The quick and reliable way of delivering content to the users increases the user experience, and in the end, that’s what every service is about. 


Read on to find out the two reasons why a CDN is essential for your online business and which other advantages it can provide for your website.

How Does a CDN Help Your Website Load Faster?

Studies show a substantial interconnection between the loading time of your website and user satisfaction, traffic, customers, and sales. According to statistics, about 53% of web users will leave your site if it takes more than 3 seconds to load. This indicates that your website may not be losing traffic because of its quality, but because of its slow loading time – an essential point that has to be taken into consideration.

Using a CDN significantly lowers the loading time of your website, providing your global users with a satisfactory website experience – and that’s just one of the many benefits a CDN can provide. If there aren’t any issues with the loading of your website, the chances that your website visitors will return to your site are way higher. Your users’ satisfaction goes hand in hand with the SEO ranking of your website, authority, reputation, and importance – which makes website speed one of the primary factors in having a successful website. 

How Does a CDN Improve the Security of Your Website?

Let’s imagine that you have local traffic only, and that has led you to believe that you don’t need a CDN. Why, when your origin server can handle all of the traffic for your small business just fine? 


Well, what you haven’t thought of is the fact that a CDN isn’t only a “fad” that big international organizations need. We hope that you don’t realize this too late because if you do, it may cost you a lot. Apart from delivering your content to your global users in a fast and reliable manner, a CDN can also add an additional layer of protection and security to your origin server.


If you rely on a CDN, then the attacks that can compromise your data won’t be able to reach your origin server. This is because CDN edge servers have the role of a shield that protects your info on your origin server from attacks, bots, malware, etc. 


CDNs also provide storage for content, archives and the backup of your data if needed. Your content will be secure through the Digital Rights Management which has limited access by requiring user identification and authenticity. 

What Are the Other Advantages of a CDN?

As elaborated earlier, the essential features that a CDN provides to your website are website speed and shorter loading time, as well as security from attacks and secure storage. The other benefits that a CDN can give you are:

  • Improved Website Uptime

A CDN guarantees you 99.9% of uptime. Even if one of your edge servers happens to go down, its role will be overtaken by another proxy server – the one closest to it. This way, the content will still get delivered to your end-users. The fact that your site can be reached at any point is truly amazing, and it’s one of the most basic things users expect in the tech era.

  • Perfect For Multiple Websites

If you manage multiple websites then a CDN is a great way to make sure there are no footprints across the websites so Google and other people can’t track that they are all hosted by the same person. This is especially useful for people who make use of private blog networks, LaunchCDN offers an excellent solution for this with very cheap hosting options.

  • Handling Traffic Spikes

When you first start your business you’re probably focusing on local or niche audiences – you don’t exactly expect anything big to happen overnight. But you can never be sure of that, can you? So, a CDN will always be helpful in handling traffic spikes that can happen quite unexpectedly.

  • Optimized for All Devices

With a CDN, the content that needs to be delivered to your users will be automatically optimized to the device of the user. Therefore, a CDN has the purpose of providing a pleasant user experience, no matter the device your visitors are trying to reach your site from.
