How to Use a Content Delivery Network (CDN) with WordPress
In this article, we’ll introduce you to the basics of using a CDN and discuss why it’s a smart idea. Then, we’ll look at 9 CDN solutions you can use on your WordPress site.
The world is moving faster than ever, and that means your website needs to keep up. No matter where you are in the world, chances are your users are scattered across the globe. For that reason, you need to make sure that your site is capable of performing quickly, regardless of geographic location.
One way you can keep your site’s speed and performance consistent is by using a Content Delivery Network (CDN). A CDN is a network of remote servers spread out all over the world, each of which contains a copy of your site that visitors can access. Not only will this make your site faster, but it can also help to secure it and reduce your bandwidth usage.
An Introduction to Content Delivery Networks (CDNs)
While the two may seem similar, it’s important to recognize that a CDN is not the same thing as a web host. Your host is the server where your site ‘lives,’ and is sometimes called the ‘origin server.’ The CDN servers simply copy static files from your origin server to deliver them to your visitors more quickly.
The Benefits of Using a CDN with Your Site
Normally, when a user visits your site, they connect directly to the origin server through their browser and download all the necessary files from there. However, this can lead to problems for users who are located far away from the origin server. This distance can cause significantly longer loading times.
Your site’s speed can negatively affect its bounce rates, which can, in turn, be catastrophic for your conversions. Therefore, this is not a small issue. Since all visitors are requesting the same files from one server, you may even experience more downtime.
That’s where a CDN comes in handy. When you use a CDN, visitors will instead connect to your site via the server closest to them. That way, your pages load much faster and will cause less strain on your origin server.
Using a CDN also:
- Makes your site more crash-resistant. If one CDN server goes down, the site will simply load from another. This enables you to handle more traffic.
- Improves the user experience. The fact that your site is effectively spread across the globe creates a more consistent experience for all visitors.
- Improves your SEO ranking. A site’s speed is factored into its search engine rankings, so speeding it up makes it more likely to appear higher in search results.
- Reduces bandwidth usage. Since your origin server doesn’t need to send as much data to each visitor, you minimize the amount of bandwidth needed.
- Helps protect against basic attacks. A CDN is designed to cope with large amounts of traffic, which helps against the most common types of malicious activity, such as Distributed Denial of Service (DDoS) attacks.
As you can see, using a CDN can help improve a lot more than just your site’s speed and reliability. The only question left is how to get started. Let’s now take a look at some of the best CDN solutions you can implement on your WordPress site.
