A: It means you can use this license for the specified number of sites. If your license covers five sites, you can install and use the plugin on up to five different websites. If you have an unlimited site license, you can use the plugin on as many sites as you want, whether it’s your clients’ websites or your own multiple projects.

This does not limit the number of directory entries or listings you can create within those sites—it’s only about how many sites you can install the plugin on.
