What is Multisite?

Updated on October 21st, 2020

A multisite network (or “Multisite” for short) is a collection of sites that all share the same WordPress installation and database. These sites can also share plugins and themes that can be managed and updated network-wide. Multisite installs are great for projects that include an umbrella site.


A restaurant group with multiple locations or a college with multiple departments. Each location or department could be a sub-site of the parent site and management could administer each site from a single WordPress dashboard.

Should I use Multisite for my project?

Multisite is not appropriate for all projects and sites. WordPress Multisite networks require a higher level of WordPress developer knowledge to set up and manage.

Due to the fact that these run on shared server resources and a single database, we strongly advise against trying to include too many vastly different child sites inside a single Multisite, especially if there are going to be a lot of different themes or plugins involved. Doing so can cause network-wide performance issues or even downtime.

If you have any questions about if Multisite is a good solution for your project, contact one of our WordPress experts.
