A content delivery network (a.k.a CDN) is one of those things you hear whenever someone is talking about speeding up a website.
But what is a CDN and why is it useful?
CDNs have become one of the easiest ways to make your site load faster. In fact, all speed checking tools like GT Metrix and Google Page Speed suggest using a good content delivery network (CDN) to improve a site’s performance.
People with technical backgrounds are aware of what CDNs are and the benefits of using a content delivery network. But for non-technical people, the concept can seem alien.
Well, there’s nothing to worry about because, in this blog post, I will be talking in-depth about content delivery networks and why you should be using one.

What is a CDN a.k.a Content Delivery Network?
Let me start out in layman’s language.
We bloggers and website owners usually use shared hosting, and all of our files are hosted at a data center. For example, my site is hosted with Kinsta hosting, and I’m using a Texas (USA) data center.
Now, when a user opens ShoutMeLoud.com, their request goes to my data center in Texas, and the files from my site load onto the user’s browser. Sounds simple, right?
But if the user is far away from my Texas data center, there will be many high pings and latency, and thus, it can take a lot of time for the site to load.
Now, a content delivery network has data centers in different geographical locations, and when your site is using a CDN and a reader or customers opens your site, your files (images, static files, etc.) are served from the nearest data centre of the CDN you are using. This reduces the pings and latency, and your site serves faster.
This is the first and prime benefit of using a CDN.

In other words, they use a technique called content replication. This is where your content is copied on different servers located in different regions.
A good CDN service will have multiple servers in different locations. When you are serving your WordPress (or any other website) files using a content delivery network, you are essentially saving the time of your readers and reducing the server load. Files will now be served from other servers and not your hosting company.

When you configure a CDN, you use the pull or push technique to upload your existing files to a server.
Here is a self-explanatory image from MaxCDN which explain how this works:
Benefits of using a CDN
There are many direct benefits of using a CDN:
- Your page speed improves (and ranking will improve).
- Your readers/clients/customers will be happier.
- You can handle more traffic.
- You will be saving money on your limited bandwidth hosting.
1. Google Ranking
Google has made it clear that page load time is one of the search engine ranking factors. By using a CDN, you will be speeding up your site by a great extent.
Moreover, it will help you reduce the bounce rate (which is also good for SEO).
For any website, the faster it loads, the better it is.
2. More Conversions and Sales
Because your site loads faster, your readers and clients will be much happier.
Where there are happy clients, there are more sales.
I’m willing to bet that you would be pretty frustrated to do business with someone whose website took ages to load.
3. Handle More Traffic
Whenever your blog posts go viral, your server gets a huge amount of traffic. Many times, your site crashes and gives errors like: “Internal server error” or “Database error”.
With a good content delivery network service, you can easily minimize such down times and your site can handle a lot more traffic.
4. Reduce Hosting Cost
When you are using dedicated or VPS hosting, or any limited bandwidth hosting, using a CDN will reduce your costs by a great margin.
CDNs are way cheaper than web hosting, and since your files will be served from CDN servers, you need not worry about the bandwidth cost of your web hosting.
If you are still not convinced and are still not sure about the benefits of using a CDN, here is a simple video which explains it all:
It doesn’t matter how big or small your site is, using a content delivery network service will surely help you boost your site’s load time and server response. The only hard part for newbies is setting it up.
