What Is WordPress Multisite?
Multisite is a built-in WordPress feature that allows one WordPress installation to host multiple websites. Each site shares the same WordPress core, plugins, and themes but has its own content, settings, and user base.
When to Use Multisite
Multisite is ideal for organisations managing multiple related sites — a university with department sites, a news network with regional editions, or an agency managing client sites centrally. It reduces maintenance overhead significantly.
Setting It Up
Enable Multisite by adding SUBDOMAIN_INSTALL and WP_ALLOW_MULTISITE constants to wp-config.php and updating .htaccess rules. Then use the Network Setup wizard to choose between subdomain (site1.domain.com) or subdirectory (domain.com/site1) structure.
Limitations to Know
Not all plugins are Multisite-compatible. Plugins must be network-activated or activated per site. If one site has performance problems it can affect all sites on the network. For very large or high-traffic sites, separate installs may be more appropriate.
