How domains are counted by our license checking system

Each separate WordPress installation where you activate our product counts as one license activation.

What counts as a separate activation

The following are always counted separately if they are different WordPress installs:

Main domains (e.g. example.com )
Subdomains (e.g. blog.example.com , staging.example.com )
Subdirectories (e.g. example.com/test-site )
Staging, development, or testing sites

Using the same license key on multiple sites is allowed only if your license includes enough activation slots.

Subdomains do not share the activation of the main domain.

WordPress Multisite

In a WordPress Multisite network, each sub-site where the product is activated counts as one activation, whether the network uses subdomains or subfolders.

A special multisite license key is not required—you only need enough activations for the number of sites.

Managing activations

If you reach your activation limit, you can deactivate the license on an unused site and reuse that activation elsewhere.
