For the purposes of our licensing, we count one “site” as one installation of WordPress & OptimizePress. So if you have a site where you have installed WordPress and OptimizePress, whether on a subdomain or main domain, that will require one license
If you have further subdomains attached to a multi-site on the same main domain, these will each require their own license.
Remember: You can build an unlimited number of PAGES on each site that you install OptimizePress (landing pages, sales pages, membership pages etc) – your only limitation is your hosting webspace and bandwidth which is set by your chosen hosting company.
