Advanced Web Ranking comes with a feature that allows multiple clients to connect to the same database. This is acomplished by connecting all the client applications to a TCP/IP server that has access to a local (centralized) database.

When you purchase a Server license, you actually purchase an Enterprise client license and the ability to run the Advanced Web Ranking Server. You can connect to this server with as many clients as you have purchased regardless of what license type the clients have: Standard, Professional or Enterprise.

The Server license comes with an Enterprise client license, so when you purchase a Server license you can connect to it with the Enterprise client using the same license key.
