The Best CDN Services For WordPress

CDN, short for Content Delivery Network, improves your website’s performance by loading content in a few seconds on your visitor’s device. Not only does a CDN save bandwidth costs from your hosting provider, but your site becomes insanely fast and tends to rank higher in the search engines. While you may think that a CDN is a hosting service or some type of server, it actually uses the cloud to store content and deliver it to visitors from a server that is closest to where they live. This guarantees that your visitors see content within seconds of loading your WordPress site. 

In this post, we will help you find the best free CDN for WordPress so that you can serve your images and other static files from a network of servers around the world. But first, let’s address what is a  CDN and how they function.

What is a CDN?

To put it simply, a CDN helps close the distance and bulk between your website and your website’s visitors. It is a bunch of servers, located across the globe, designed to deliver your website’s files to the site’s visitor in the fastest time. So, regardless of how many large media files, images, or pages you have on your website, a CDN allows your visitors to experience and interact with your website just as fast as if they were locally based. i.e it speeds up content delivery by serving the content from the server that is closest to the visitor.

For websites with a lot of traffic or with a global audience, this is a huge deal. So, instead of discarding your video assets, or trying to find more WordPress plugins to help with compressing image files – you can turn to a CDN to improve your website’s performance (as well as security, stability, and more).

How does CDN work?

With a regular WordPress site, you use a single location server to host your content including images, web pages, blogs, articles, links, etc. All of your visitors go to your website through this single server. This can generate delay in page load speed of your site. To tackle this situation, CDNs were delivered to cache a server’s resources as static content through javascript, images, and stylesheets. 

When a user connects to your site, they request this information and get the static sources delivered through CDN servers nearest to their location. This reduces the entire load on your original WordPress site’s server and makes it faster for users to connect around the world. 

Basically, there are three main components to a CDN:

1. Website files: Theme files, scripts, images, videos, and other static files need to be easily and quickly accessed when someone visits your website. It’s the distance between your site visitor and those files that usually cause your website to load slowly.

2. Pull URLs: When you work with a CDN, you need to have a location from which the global servers can make duplicates of your files. This file directory is known as a ‘Pull URL’.

3. Edge servers: Your main hosting server resides in one or maybe two locations. So when someone visits your website, they are trying to access files from that server’s specific location.

What makes a good CDN?

There are certain features to look for while selecting a CDN:

  • DDoS Security: Most CDN services offer DDoS mitigation or some form of DDoS protection. This is the best way to protect your website from malicious viruses installed by hackers to worsen and abuse your site’s database.
  • Bandwidth: Most CDNs will supply you with some amount of bandwidth per month that you can use for free. At the lowest, you may get 200 GB. However, if you want a powerful site that services a lot of traffic, you may need nearly 2500 GB in bandwidth.
  • Network Performance: If the majority of your site’s visitors are based in the US, it makes sense to go with a CDN with servers spread across that region. However, if you have a spread of visitors from across the US, Europe, and Asia, it would be better for your content to be available on servers in those regions.
  • Image Optimization: One of the reasons that websites lose speed is because of large, high-resolution images. A CDN should offer image optimization that lets your images and websites load in a second.
  • Customer Support: You may not need managed support or an engineer on standby, but 24-hour round-the-clock tech support is essential when you are purchasing any kind of CDN. 

Now let’s move on to the list of best CDN services for WordPress sites.
