Use a Content Delivery Network (CDN)

The people who visit your website belong to various locations in the world, and needless to say, the site-loading speed will differ if the visitors are located far away from where your site is hosted. There are many CDN (Content Delivery Networks) that help in keeping the site-loading speed to a minimum for visitors from various countries. A CDN keeps a copy of your website in various datacenters located in different places. The primary function of a CDN is to serve the webpage to a visitor from the nearest possible location. Cloudflare and MaxCDN are among the most popular CDN services.

The easiest way to use a CDN with WordPress is to install a plugin. We recommend Cloudflare, which protects and accelerates your site with minimal configuration required. As well as improving your site’s speed and security, Cloudflare also provides extensive analytics detailing your site's performance.

However, do keep in mind that not all websites need to use a CDN. It’s a sort of "next-level" optimization, a usually paid third-party tool the use of which is not always strictly necessary. A CDN is crucial only if you’re managing a high-traffic website with an important goal and are thus determined to provide the best possible experience to your users.
