WordPress CDN integration in 2024

Introduction

WordPress stands as one of the most renowned content management systems (CMS) globally. With nearly 22.5% of all existing websites worldwide powered by WP, its popularity remains unparalleled. This robust system is favored for its:

  • Effortless installation, operation, and customization.
  • Cost-free accessibility.
  • Abundance of free templates, themes, and plugins.
  • Search engine optimization (SEO) friendliness.
  • Intuitive control and management.
  • Robust security features.

Leveraging a Content Delivery Network (CDN) with WordPress can significantly enhance loading speed. Below, we provide comprehensive instructions on integrating a CDN with WP.

Before you start

  • Before you take any steps please back up your files and database.
  • In the following, we will integrate a CDN service using the CDN domain 12345.r.cdnsun.net. Please visit the Services/How-To section to obtain your CDN domain.
  • To integate a CDN service on https:// website you can use https://12345.r.cdnsun.net or you can use a custom CDN domain with SSL enabled.
  • If your website embeds custom fonts then please first enable CORS for them.
  • Before you take any steps please make sure that your CDN domain is ready-to-use here.
