A superior user experience is everything when it comes to administering a website. On the one hand, the user expectations are immense; the site should provide information, media, and engagement. On the other hand, the Internet is growing, making it harder and competitive to provide a tremendously user-friendly website. Given the upcoming advancements focussed on loading, interactivity, and visual stability, it’s the perfect time for your business to audit your site’s performance. Perhaps you’ve heard that one major constituent of this should be a reevaluation of the site’s Content Delivery Network (CDN) set-up.

Read on to find out how a CDN can speed up your web assets, why it matters for SEO, and how it can become the backbone of your website conversion strategy:

What is a CDN?

It’s imperative for businesses not to miss out on the power of CDNs and explore how a CDN works behind the curtains to deliver fast, efficient and secure delivery of your content to websites and Internet services. Research shows that a 2-second delay in the load time for your website can lead to more than a 4% loss in consumer satisfaction and a 4.3% loss in revenue per user.

A CDN is a distributed model of servers designed to deliver web content ASAP to end-users. Without a CDN, your server might go offline and prevent visitors from accessing your site and its content. Therefore, CDNs are fundamental for improving websites’ speed and overall performance that may have a global reach and those experiencing surges in traffic or high traffic regularly.

How Does it Work?

To avoid the dissatisfied users generated by slow service, CDNs move content closer to the user to overcome latency and improve the UX. However, there are quite a few intricate technical challenges in its workings.

First, to overcome the latency for any user, a CDN must have a content caching server nearby. Caches are organised into PoPs, distributed throughout large geographic regions, and placed in major population centres within those regions. Next, CDN providers often place servers at Internet Exchange Points (IXPs), the physical location where internet service providers connect and exchange traffic. Lastly, as a request is being processed, the CDN references the index and conducts the user’s traffic to the closest available server in that region. Thus, potentially any data that can be digitised can be delivered via CDN.

Types of CDNs

CDNs expand the end-to-end carrier networks by disseminating on it a variety of intelligent applications using techniques intended to optimise content delivery. There are essentially two primary set-ups for a CDN: a P2P (Peer-to-Peer) network and a peering or private model. However, security can be breached through a P2P CDN; it’s better to adopt the second type.

P2Ps are decentralised and made up, primarily, of the data of users that have been opened up to permit anyone to look for specific files to pull from their computers through the use of a server termed as ‘tracker.’ Whereas, in the peering or private CDN model, a firm can manage a system of servers across a broad geographic area. This speeds up loading times and helps to keep the site from crashing.

What Can it Do For Your Website?

For any site developer or business owner, the ultimate benefit that a CDN solution offers is enhanced user experience by reducing latency in capturing real-time digital data and content. In addition, geographical locations play a crucial role in latency and download speed as the CDN will distribute traffic to the nearest available PoP (Points of Presence). Thus, a strong CDN network helps reduce webpage loading time and increases the data transmission rate.

The CDN solution providers distribute the user requests amongst all the CDN servers to minimise the load. Load balancing of CDN also aids in evading overloaded servers and crashes. A CDN provider usually handles nearly half the volume of Internet data traffic, resulting in large volumes of analytical information generated. This is shared with the end-users to drive actionable insights.

Final Words

The farther the users are from a company’s information centre, the more delayed its app/website loads — producing a frustrating and inconsistent user experience. This problem can be corrected via a content delivery network (CDN). A CDN keeps a site secured to make sure that a high standard of integrity, encryption, and authentication is delivered. Companies ought to examine their security concerns, and figure out what can be done by CDNs to deliver content securely. Whether you’re using a platform with an in-built CDN or waiting to integrate one from a third-party vendor, a CDN service shall facilitate you to build or grow into a high-traffic website that extends to a global audience.
