5 Best Free CDN Plugins For WordPress & How To Set It Up
Improving your website loading speed takes a very important role in ranking your website on Google. And one of the best ways to supercharge your website is to use a CDN.
In this guide, we explain what a CDN is, why you should use one, and show you how to set up a CDN in WordPress for free.
Even though it may sound like a very advanced process, installing a CDN is quite easy. Thanks to WordPress CDN plugins, you can get it done in just a few steps.
We’ll walk you through the process. First, let’s see what these CDNs are really about.
What is a CDN?
A CDN, or Content Delivery Network, is a system that allows you to store the core resources of your website on the cloud to serve them to your visitors much faster.
When using a CDN, the images, code scripts, and the main elements of your website get stored on a network of servers provided by the CDN. Whenever a user visits your website, the CDN serves your site content to the visitor using the nearest server.
For example, CDNs have servers located around the world. So if a user from Australia visits your website, the CDN will use the nearest server to that location to serve your website content to that user.
As you can imagine, it reduces the time it takes to connect a user to your website, resulting in faster page load times.
Why Use a CDN?
If you want your website, articles, and pages to rank higher in Google search results, you should do everything you can to improve the loading speed of your website.
Google has been using the page loading speed of websites as a ranking factor for many years. Recently, Google introduced Core Web Vitals, a new set of guidelines for optimizing websites for better SEO (search engine optimization).
The first and the main aspect of the Core Web Vitals is “loading”. The time it takes to load a page on your website will determine how Google ranks pages on search results pages. Your website should load in under 2.5 seconds to improve the chances of getting better rankings on Google.
Using a CDN goes a long way to help boost your website loading speed. Since it delivers your website content based on the visitor’s geo-location, your websites will load much faster with minimum delays.
