In this article, we will show you why you need a CDN for your WordPress blog.

Why You Need a CDN for Your WordPress Blog


What is a CDN and Why you need a CDN

To find out what is a CDN, simply click to view the infographic. You can also continue reading our article for written details.

Note: Just to clarify, CDN is something you use on top of having a web hosting account because it helps speed up things.

CDN does not replace a web hosting account, as you still need to have a hosting provider like SiteGround or Bluehost.

What is a CDN?

CDN is short for Content Delivery Network, which is a network of servers that deliver cached static content from websites to users based on the user’s geographic location.

If this sounds overwhelming, then let’s break it down in simpler words.

How Does a CDN Work?

Normally, when a user comes to your WordPress blog, their browser downloads the website from your web host’s server (i.e. HostGator). Your web host’s server is located at a physical location, for example, Houston, Texas.

What this means is that every user is accessing this one server in Texas to view your WordPress website. Now, if you have a high volume of traffic, then you can overload your server, which leads to a slow loading site or even server crash.

This is where a CDN comes in handy. A CDN is a network of servers that are spread throughout the world. When you use a CDN, your static content is cached and stored on all of these servers.

How does a CDN work

Static content includes images, stylesheets (CSS files), javascript, and more. When a user visits your website, the CDN technology redirects them to the closest server to their location.

For example, if your main server is hosted in Houston, TX, and someone from Durham, England tries to access it, then they will be redirected to the closest server, which may be in London.

This limits the number of internet hops needed to transmit the static files to your end-user. Because the user’s computer is closer in location to the CDN server, the files will load faster.

By having your content available on multiple servers around the world, you can make your pages load faster from the user’s perspective. In simple words, the closer the CDN server is to where your user is, the faster the user gets the content.

Now, you may be wondering if a CDN is worth it on your website? Let’s look at why you need it for your WordPress blog.

Why Do You Need a CDN for Your WordPress Blog?

Having a CDN can impact your website’s performance and boost the user experience. Below are some of the advantages of using a CDN:

  • Speed – A CDN helps improve the page load time of your site and makes it faster.
  • Crash Resistance – Using a CDN allows you to distribute the load to multiple servers instead of having 100% traffic to our main server, thus making it less likely to crash.
  • Improved User Experience – With a CDN making your website faster, you’ll noticed a decline in bounce rate on your site. It also increases the numbers of pages viewed by each user. Clearly, a fast site means improved user experience.
  • Improvement in SEO – Google has stated that faster sites tend to rank higher in search engines. A CDN can boost your WordPress SEO and help you achieve higher keyword rankings.

Which is the Best CDN for WordPress?

There are many WordPress CDN services in the market. We recommend as the best CDN provider that you use for your WordPress website. It has servers spread across the world and offers affordable pricing plans.

If you’re looking for a CDN service that also provides security features, then we suggest using Sucuri. It offers a powerful WordPress firewall and CDN to protect your site from different threats while ensuring fast load times. We use Sucuri on WPBeginner as a CDN and website security plugin.

  1. Thanks for this helpful article.

    I am with Bluehost and recently I selected CDN and noticed that my website was loading much faster. But, some users could not access my website as the following message came up:


    I got Bluehost to revert back to my original setting. Is their a way around this?

    • You would want to reach out to BlueHost’s support and they should be able to assist.


  2. Hello

    will I be losing all my blog posts if I changed my host from Hostgator to CDN network?

  3. Thank you for clarifying the purpose of a CDN. A very straightforward and easy to understand explanation. wpbeginner is a great resource and I’m starting to appreciate your value to the WordPress community!

  4. Can you please compare some Free CDN service for low traffic site which can’t afford services like MAX CDN. Cloudflare, Incapsula and Amazon are offering free cdn but don’t know which one to choose.

  5. Thanks for interesting post.
    If I understand it correctly CDN is useful for websites with international orientation, but not for websites with a national user base. I am located in the Netherlands (small country), and my website is focusing on people in the Netherlands. Am I correct that CDN is not going to improve loading speed for my customers?

  6. If a CDN is serving static content, why would one *also* need server-side and client-side caching?
