Improving page loading speed is one of the important factors in search engine optimization. Caching and and optimizing the content delivery can drastically improve the speed of your website. WordPress has free plugins like W3 Total Cache and premium caching plugins like WP Rocket for optimization. However, choosing the content delivery network is outside the scope of your WordPress installation. Hence, you have to look carefully before choosing the best CDN for your WordPress site.
What is CDN?
Before we go further with list of CDN provider, you have to first understand what is a Content Distribution Network (CDN)? Most WordPress site uses static files like images, videos, CSS and JS files. Every time when a user opens your website, all these static files need to be served from your hosting server. This may be an easy task when the user and server are in the same geographical location. However, this is not the case in general.
Most web hosting companies are based out of USA or offer servers from one of the US states. When a user from Australia opens the site hosted on USA server, it will take few seconds in the network for the static files to reach the user. It may even delay more depending on the internet connection speed of the user. In addition to delay in page loading speed, your web server will face lot of load for serving the files for every request all over the world.
CDN caches the static files of your site and serve from the nearest location of your user. This will help you in the following ways:
- Reduce the page loading speed by serving static files from the nearest server.
- Save bandwidth of your hosting server as the CDN servers will serve the cached content instead of communicating with your hosting server.
- Some CDN also offers firewall and filter bad bots to protect your site from hackers.
Integrating CDN with WordPress
Unlike caching plugins that you can install on your site, there are different ways to integrate CDN in WordPress.
- Change your nameservers to CDN servers in DNS zone editor of your domain. This will route all your traffic through the CDN server.
- Create zones for static files and assign CNAME for that zones in your DNS settings.
- Integrate CDN using caching or a dedicated plugin.
