The loading time of your page has a vital role in your website visitor’s user experience. And it can be one of the major contributing factors to page abandonment by your visitors. That's why so many people use free CDNs to boost their loading times.
According to a survey, 40% abandon a page that takes more than 3 seconds to load. Even worse, 79% of web shoppers say that they won’t return to buy again if they found any trouble with the performance of the website.
Undoubtedly, boosting your website speed is critical to the success of your online business. This is where a free content delivery network for WordPress can make a huge difference.
Why the need for speed?
When was the last time you checked how fast your site was performing? Was it fast enough or need some remarkable speed improvements? Well, no matter how smooth, lightweight and speedy your loading times are at your own location, chances are a user is experiencing a significantly slower load-time than that of yours in a different country or geographic location. Wondering, why?
Incidentally, if you are looking to make your website load faster, there are a few plugins such as this one which can make a real difference in performance in a few minutes (with little to zero effort).

What is a CDN and how can it boost your WordPress website speed?
A content delivery network, sometimes also known as a content distribution network, is essentially a geographically distributed network of super powerful proxy servers designed to host static content and deliver a cached copy of the static files to the users based on their geographical location.
The main goal of this network is to make your site load super fast by delivering all its static files to users with the lowest possible latency. To better understand how a CDN actually works, check out this handy graphic from GTmetrix:
So essentially, a Content Distribution Network is a network of multiple servers that are distributed at different locations throughout the world. It caches all the static content and files of your site and delivers it to your visitor based on the geographic locations of the user through a server that is closest to them.
Below image can help you understand how the concept works and how it can boost the speed of your domain.
The way such a service works is very simple. Unlike your hosting provider, which serves your resources from a single location, the service copies all the static resources of your WP to its network of high-speed servers.
Every time a user attempts to access your website, the service then automatically redirects the request from the original host server to the server nearest to the user’s physical location and serves user the cached files. This process cuts down the overall traveling time of your website’s data, which eventually leads to faster page load times, improved search engine rankings and a much better user experience.
There are three main types of content delivery networks:
- Content Service Protocols: These are fully managed hosted networks designed to provide users access to the website files. The services we’re discussing in this blog post falls under this type.
- Peer-to-peer CDNs: With a very small setup and running cost, peer-to-peer (P2P) setups work between personal computers and therefore are not great for hosting your website’s files. BitTorrent is a popular example of a Peer-to-peer network.
- Private CDNs: Alternatively, if you’re not satisfied with available services, you can create your own private service. This means you have to create and manage own global network of servers to serve your static files.
Best of all, using such a service not only boosts the speed of your website but also saves bandwidth costs from your hosting provider. Moreover, having a faster site can improve your search engine rankings as well. Now, the thing is this, a lot of these services cost quite a lot, so if you can find a cheap or no-cost CDN for WordPress, it's of course so much the better because you can boost your site speed until you can afford to pay for a better content distribution WordPress service.
Depending on your budget, interest, and requirements, you can go with any one of the first or the last option. Now let’s take a look at how such a network can benefit your WP.
While the benefits of using such a service can be many, below are just a few of them:
- Speed: A dramatic improvement in the website’s performance is one of the main and biggest reasons why people opt for using this service. Shortening the physical distance between the user and the server, a CDN drastically reduces the network latency – making your site load at the speed of light.
- High Global Availability and Scalability: What if your main server goes down or crashes due to a sudden spike in traffic? When enabled, your website will always stay up and running as multiple servers are there to handle the traffic. Look at CloudFlare's Always Online technology that keeps a website always alive.
- Security: Taking advantage of cutting-edge technologies like WAF (Web Application Firewalls) and Origin Shield, a lot of providers offer an additional layer of security to keep data secure, process customer transactions and prevent DDoS, DNS Amplification, and Layer 7 attacks.
- SEO Advantages: Everyone loves a blazing fast experience, particularly Google which made speed a crucial ranking factor back in 2010. Along with helping you rank higher in search engine results, these services also increase the crawl rate of your images in Google Image Search.
- Lower Bandwidth Costs: Offloading CPU, traffic and other resources from your original hosting server, a CDN can cut bandwidth requests by up to 70%. The lower bandwidth requests are, the more bandwidth costs you save with your web host.

Do I Still Need Hosting If I Get a CDN?
This is one of the most frequently asked questions users have while they’re going to implement a CDN on their site. Well, the right answer to this question is YES. Think of your web host as a kind of virtual space that you pay to rent your online business i.e. your WP. This is the place where you actually upload and store your pages, images, videos, and everything else you need to run your domain perfectly.
A CDN, on the contrary, is something that you use on the top of your web hosting account, something that just speeds things up. Your web host remains the foundation of your domain, where you keep all your non-static files. This additional layer takes all those bulky static files and replicates them across its worldwide network of powerful servers. Concisely, these content services can never replace your web hosting account. You still need to have a WordPress hosting server to store all your files as well as WP.
Free CDNs for WordPress service
For most sites, it is very easy to implement.
All you need to do is tell the service which files it needs to be mirrored, configure your site so it can send requests to the content delivery network service for handling the files. You may also need to modify DNS records and change the name servers as well.
Additionally, if you want a free CDN for WordPress websites, you may need to install plugins to ensure your blog is running optimally on the platform.
Now let’s look at various free WordPress content delivery network services that you can opt for - which cost nothing at all. Most of these service providers allow you to upgrade to a paid service if you outgrow your starter plan which is great because it allows you to start slowly whilst you build your traffic.

It requires a number of CSS and JS files(or libraries) to be able to run the framework, and these as typically hosted on a is one of the most popular frameworks powering millions of websites around the world.

The same service also hosts FontAwesome, and Bootswatch, which are also two "tools" which require the inclusion of a number of files into your project to enable the download and usage of these frameworks.

It is currently powered and sponsored by CloudFlare, Algolia, Digital Ocean. cdnjs currently hosts over 3,000 libraries - the idea is that the service is able to host popular libraries for the benefits of developers and internet users in general.
