As a web developer, I’ve had multiple clients who needed me to create and manage multiple websites for them. This can be a daunting task, especially if you’re managing a large number of sites. That’s where WordPress Multisite comes in. WordPress Multisite is a powerful feature that allows you to manage multiple WordPress websites from a single installation. In this guide, I’ll take you through everything you need to know about setting up and managing WordPress Multisite.

Introduction to WordPress Multisite

WordPress Multisite is a feature that was introduced in WordPress 3.0. It allows you to create and manage multiple WordPress websites from a single installation.

Each site in the network can have its own domain name, subdomain, or subdirectory.

WordPress Multisite is ideal for anyone who needs to manage multiple websites. It’s especially useful for businesses, organizations, and web developers who manage websites for multiple clients. With WordPress Multisite, you can save time and effort by managing all your sites from a single dashboard.
