Understanding a CDN Domain and why you need it

CDN Domain

A CDN domain is a collection of interlinked servers located across the world. They rely on geographical closeness as the main principle for circulating cached web pages and content to end-users. As a result, every user receives the content they desire from the closest server which accelerates the whole process. Whether there is an increase in web traffic or inadequate bandwidth, end-users receive the content they need with ease. Read along for more details on how CDN works.

Why Do You Need a CDN Domain?

A CDN domain name avails your content to many people from different parts of the world which benefits your website in various ways. Some of the benefits of having a CDN domain include increasing the speed of your site. With a fast website, you can be sure of giving your users a better experience. A CDN circulates bandwidth across different servers as opposed to handling your traffic in a single centralized place. Fast websites rank high in search engines which is an excellent way of enhancing your SEO. Other CDN benefits include:

Prevents Website Crashes

A CDN cuts down the amount of traffic that your main server would have handled. Execution of this process is achieved by delegating end-user content distribution to other servers across the globe. Doing so blocks high traffic volumes that could trigger a website crash. CDN clears oncoming traffic to your site enabling it to perform faster and better which boosts your site’s load time significantly.

The load time of your website pages can impact your conversion rate. Consider optimizing it to avoid losing the number of visitors coming to your website and even revenue. The slightest delay in your website load time can cut down your conversion rate significantly. It can also cut back customer satisfaction and page views.

To avoid this you need to engage reliable CDN providers who can accelerate your website. Remember, customer satisfaction is critical for every business. When your customers are happy there will be an improvement in your overall business and it will also increase your revenue.

Improves Your Website’s SEO Ranking

Search engine optimization is critical for each website owner. A CDN domain speeds up your website and improves user experience which is crucial when it comes to SEO ranking. This happens because Google highlights website load time and user experience to rank your website in search engines.

How does a CDN Domain Work?

Many CDNs run as ASP (Application Service Provides) or SaaS (Software as a Service). Some internet network proprietors started developing their CDN to enhance online content delivery. Their main goal is to boost its infrastructure and generate more revenue. CDN domains operate in various ways as we shall see below.

Content Networking Techniques

CDN domains use a range of content networking techniques to improve content delivery like server load modification, web caching, content services, and request routing.


To reduce the distance between end-users and your site’s server a CDN domain maintains static cached server content of your site on different geographical locations. These are data centers known as PoPs (points of presence). Each point of presence comprises servers and nodes, some of which hit thousands of servers and nodes. These components help circulate content to end-users, based on their geographical location.

They also accelerate content delivery. When users request to view your website, the request is sent to a DNS server. A CDN then forwards the request to the nearest PoP. The node that is nearest to the user presents them with static content which reduces dormancy and enhances user experience.

Considerations to Make when Choosing a CDN

Choosing a CDN can be a difficult task seeing that there are different solutions in the market today. Use the following factors to make an informed choice.

User Geography

Determine where your customers are mainly located. For example, if they are in the UK, you want a CDN that offers excellent international coverage. If a majority of your customers are within your locality, then local hosting without CDN could be ideal.

CDN Performance

Every website owner wants a fast website. If the CDN you choose will slow down your site then it would be of little help. Before choosing a CDN domain you should devise a performance evaluation methodology that helps you make an informed decision. There are various specifications to beware of like a stress test, location, synthetic vs. RUM, and the performance situation you are comparing to.

CDN Availability and Reliability

End-users will be connecting to your website through a CDN, and you will need to guarantee maximum availability and uptime. Evaluate CDNs on their capacity to be liable to SLA (Service Level Agreement).

A CDN Domain is Essential

A CDN domain gives your website excellent value when it comes to efficiency, speed, and improved security. Consider it to improve user experience, increase the number of visitors on your website, and double your revenue.
