What is WordPress CDN? How does it Speed up your website?


The number of WordPress hosting providers has skyrocketed in the last few years. The increased competition has increased the number of low-quality hosting services that have little to no experience in running WordPress websites, which inevitably causes performance-related issues, just because the server doesn’t have the necessary caching features to optimize your website.

There can be multiple reasons for your WordPress website to be slow, but the root cause is usually improper server configuration. The biggest problem is that WordPress plugins created by different developers can work in an incompatible way, which results in poor optimization. WordPress CDN accelerates these plugin scripts by caching them on their servers.

We embrace researching and sharing techniques to make your WordPress site faster as a performance hosting provider. Using a content delivery network is one of the no-brainers when it comes to speed these days (CDN). They relieve the strain on your web server by speeding up the transmission of material to your visitors, improving their overall experience!

Today, we’ll discuss how a WordPress CDN works, why you should use one, and some of the additional benefits that come with it in layman’s terms. We’ll also show you some speed tests so you can see how much of a performance gain you may expect on your own website.

This article offers a thorough overview of WordPress CDN. It discusses what is CDN and how does it improve page loading speed. In the article, we have put forth different practical reasons why you should consider using a Content Delivery Network for your WordPress website.


Introduction of WordPress CDN:

The term CDN is an abbreviation for “content delivery network.” These are a worldwide network of servers (sometimes referred to as POPs). They’re made to host and distribute static (and sometimes dynamic) material including photos, CSS, JavaScript, and video streams from your WordPress site.

A CDN is a collection of web servers, distributed all over the world. This way, the site visitors get closer to their hosting server and hence superior site performance. The websites that utilize WordPress require CDN for blazing-fast speeds that will enable speedy delivery of your content to users around the world. 

There are a variety of variables that might hinder the performance of your website, but the most common is a lack of a good web hosting provider. However, there is a solution to the problem: CDNs. They have the ability to boost the loading speed of your WordPress website right away. However, most webmasters are unaware of how to use CDNs since they appear to be too complicated.

Why Is WordPress Site Speed So Important?

According to studies, the average human attention span has decreased from 12 seconds to 7 seconds between 2000 and 2016. What does this mean for you as the owner of a website? You just have a few minutes to show consumers your content and persuade them to stay on your site.

Users may abandon your website before it even begins to load if it is too slow. According to a StrangeLoop case study involving Amazon, Google, and other major sites, a one-second delay in page load time can result in a 7% drop in conversions, an 11% drop in page views, and a 16% drop in customer satisfaction.

Furthermore, Google and other search engines have begun penalizing slower websites by ranking them lower in search results, resulting in traffic for such sites. To summarise, if you want more traffic, subscribers, and money from your website, you must optimize it for speed.

How to Test the Speed of Your WordPress Website?

Beginners frequently believe that their website is OK simply because it does not appear to be slow on their computer. That’s a huge blunder. Modern browsers like Chrome store your website in the cache and automatically prefetch it as soon as you start typing an address since you visit it frequently. Your website will load almost instantly as a result of this.

A normal person viewing your website for the first time, on the other hand, may not have the same experience. In fact, users in different parts of the world will have very diverse experiences. This is why we recommend utilizing a tool like IsItWP’s WordPress speed test to check the speed of your website.

It’s a free online tool that lets you test the speed of your website. You might be wondering, “What is a good website speed that I should aim for?” once you’ve completed your website speed test. Under two seconds is an excellent page load time. The faster you can make it, though, the better. A few milliseconds saved here and there can build up to half or even a full second saved on your load time.

How do CDN works?

First and foremost, don’t confuse a CDN with your WordPress hosting provider. These are two entirely different services. A CDN isn’t a replacement for your hosting provider; rather, it’s an additional approach to boost your site’s speed.

What is a CDN and how does it work? For example, when you host your website, you must select a physical data center location, such as the United States Central, Europe, South America, or Asia. Assume you select US Central. This indicates that your website is physically located in Council Bluffs, Iowa, on a “host server.” When people from Europe visit your website, it will take longer for it to load than if they were from, say, Dallas, Texas. Why?

Because the information must go a greater distance. This is referred to as latency. The time and/or delay associated with data transmission through a network is referred to as latency. The longer the distance between two points, the longer the latency.

Serving data requests from browsers to hosting servers and the requested content from hosting servers back to web browsers requires many networking hops (communication instances between intermediate networking devices). This is when a CDN comes in handy. Loading your site’s content from servers closer to them helps to reduce latency. These CDN servers are also known as POPs (Points of Presence) (points of presence).

WordPress users are sometimes hesitant to investigate content delivery networks since it can be intimidating initially. So, in layman’s words, here’s how they function and can be deployed in three simple steps:

Step 1:

Choose a CDN provider and sign up for their service. These are usually priced monthly or based on data usage. The majority of companies will give you a calculator to estimate your costs.

Step 2:

To integrate it, you can use a free plugin like CDN Enabler or WP Rocket. These plugins connect your assets to the CDN automatically. You don’t have to do anything to get your material on the CDN; it’s completely automated! It’s a lot easier to set up a CDN now than it was a few years ago.

Step 3:

When customers visit your website, the content of your WordPress site is now loaded from several CDNs across the world. As a result, your content is now loaded from a POP in Europe for European visitors to your site in Iowa. 

What are their methods for accomplishing this? IP Anycast + geolocation routing are the two most common technologies used by CDNs to route users to the correct location. They can automatically recognize the source of user requests and route them to the closest POP. However, selecting a strategic server location for your WordPress host is still critical.

Because, even if a CDN aids in the distribution of your media and content, your hosting provider must still get a single request when your website is loaded. Unless you use full-page caching on a proxy server.

How does CDN speed up your WordPress Website?

When you use CDN on your WordPress website, the person that visits your page will only obtain the HTML code from your origin server. The rest of the content will be loaded from a CDN server that has been developed and optimized specifically for this purpose. Let’s have a look at how this can help your WordPress website.

The most important reason to use a Content Delivery Network is to improve the speed of your website. It should go without saying that a speedy website leads to higher conversion rates, a better user experience, lower website traffic, and longer visits.

Because the majority of your website’s loading time is spent downloading static resources such as photos and CSS stylesheets, it’s easy to deduce that employing a CDN will speed up your site. This is mostly accomplished through the use of file caching concepts. Caching is used by Content Delivery Networks to deliver your files to users’ browsers faster, the same how caching plugins are used by WordPress websites.

CDN’s heart and soul are caching. This is accomplished by transferring your static content files to considerably more powerful proxy servers that are specifically designed to distribute material more quickly.

The closer the cache server is to the user, the less time it takes for your page’s whole data to be loaded into the browser. The RAM on these machines has been increased, and the storage is SSD. The RAM is utilized for the most important stuff, while the SSD is used for less important content that is still cacheable and can be requested by users.

One of the most compelling reasons to use a CDN is to improve performance. A faster loading site has been demonstrated to correspond with increased conversion rates, lower bounce rates, and a longer average visitor duration time after time. That’s not to mention a generally improved user experience. 

When was the last time you hit the back button on your browser because a website took too long to load? This is exactly what you don’t want to happen. But don’t take our word for it; here are some brief numbers from some of the industry’s most respected figures:

  • A 1-  7% drop in conversions can be caused by a second delay in page response.
  • The BBC has discovered that for every additional second it takes for their site to load, they lose 10% of their users.
  • According to statistics from Google’s DoubleClick, 53% of visits to mobile sites are abandoned after 3 seconds.
  • AliExpress observed a 36 percent reduction in load time, a 10.5% rise in orders, and a 27 percent boost in new customer conversion.

Here are a few ways that a CDN can help your WordPress website speed up.

  • Reduces TTFB: As previously mentioned, a WordPress CDN can help reduce latency by reducing the physical distance that data must travel. However, it can also help you get to the first byte faster (TTFB). To put it another way, this is the time it takes for the browser to get its first byte of data from the server. The longer it takes to obtain that data, the longer it takes for your website to be shown.

  • Faster Delivery Through Caching: CDNs use caching in the same way as your WordPress host or a plugin does. One of the reasons they can deliver files so quickly is because of this. However, it’s crucial to understand how caching works. After a CDN receives a copy of your material, a visitor must normally request it once or twice before it is cached on the CDN. The HTTP header “X-Cache” is added by a CDN to requests. The file will often show up as a MISS on the first or second request, indicating that it has not yet been cached.
