10 Best CDN Providers to Optimize Loading Time and Website Security

Research conducted by Google showed that 53% of users drop off if a site loads its content in three seconds. Hence, having the best CDN providers is a must to improve the site’s speed and performance.

Well, that’s true!

The loading speed of your website does matter and has a significant influence on user experience (UX) and conversion rates. When it comes to loading time, it’s called Latency. And, of course, most of you have experienced it already.

Latency is the delay when you access a website before it fully loads the content to appear on the screen. Several factors cause this delay duration, but mainly because of the distance between you and the server where the website stores the content.

And there, CDN providers come in as a workaround. CDN is designed to shorten such a distance so that audiences all around the world can see your site in just less than 2 seconds.

In this article, we’ll learn:

  • What CDN is
  • How CDN works and its benefits
  • Best CDN providers to put on.

Let’s read on to know more!

What is CDN?

CDN stands for Content Delivery Network. As its name stands for, this is a network that delivers content. It is a network of servers distributed geographically to help people across the world swiftly load web pages.

CDN oversees a quick transfer of the site’s static contents such as images, HTML pages, videos, and CSS/JS files. These files are then cached in a network of servers so that CDN will serve users with copies of web pages from the nearest server location.

We did not even know that we interact with CDN every single day. No matter what content you read and watch on the website, there are CDNs behind every single text, image, or video loaded to your PC or desktop.

These days, CDN has its popularity among website owners and developers. No wonder most of the web traffic is now served via CDNs, even for major websites like Amazon and Netflix.

How Do CDNs Work?

As explained earlier, CDNs function to minimize the distance between your web’s server and the visitors. A CDN caches the static content of your website and stores it in multiple locations or known as Points of Presence (PoPs).

Each PoP has caching servers in charge of delivering the site’s content to visitors within its proximity. In other words, the content is provided to visitors from a closer source. Hence, CDNs can detect where the visitor’s requests come from, and that way, the visitors have a faster loading time to see the webpages.

In a nutshell, CDN helps distribute your content in a cached version in so many places worldwide. As a result, it won’t be time-consuming for visitors located far from the host server.

Let’s say visitors from Indonesia access your UK-hosted website; it will be done through the nearby PoP, Singapore, for instance. They will see your site’s content much faster instead of having their request travel over the Indian and back.

As we know that CDNs work to reduce the page load time, it does bring more benefits to your website.

Let’s see what those are…

Why Are CDNs Important?

Best CDN providers will help you provide a much better UX that can attract customers and SERPs. You can leverage the existence of CDNs if you run an eCommerce business that is really eager to expand the sales area. Here are the benefits of using CDN on your website

1. Enhancing Website Security

Malicious attackers are the biggest threat in the digital world, where all kinds of transactions are done through the internet. Hence, the core competency of CDN is to serve cloud-based solutions and information security.

A Content Delivery Network can enhance website security by mitigating DDoS attacks and protecting websites from spammers over content delivery.

2. Elevating SEO Performance

As everyone knows that the faster a website is, the higher it will be ranked by search engines.

CDNs can speed up the website’s loading time so that it is trusted by Google. That’s a plus point to set your site apart from others that do not use CDNs.

Given that search engines prefer safe and fast websites, activating SSL is a must, and you can get it for free in some best CDN providers.

3. Reducing Latency and Increasing Website Speed

Well, CDN can hamper the wrong things to occur, such as Latency. As mentioned earlier, CDN stores static content such as HTML pages and images on multiple servers worldwide.

Therefore, when visitors access your site, CDN will point it to the closest server to them. This can reduce the server load and speed up the loading time of your site at once.

4. Reducing Bandwidth and Disk Usage

Bandwidth and disk usage are the primary expenses for using website hosting. Oftentimes, bandwidth can exceed existing capacity when there is huge traffic to the website.

Hence, you can use CDN to reduce the required amount of bandwidth to overcome the incoming requests to the server. CDNs help the origin server transfer the site’s data through caching and store them in the Points of Presence (POPs).

5. Skyrocketing Content Availability

Since CDNs have POPs spread geographically, it increases website content availability. What we mean by availability is your website can be accessed by lots of visitors from all over the world.

Besides, CDN can handle requests from these visitors so that they can come to your website faster. And, of course, this helps skyrocketing conversion rates.
