Hi s.id friends,
Domain sub pages are pages after your custom domain on s.id.
For example, the following s.id custom domain: https://exampledomain.id and uses the sub page domain https://exampledomain.id/domainsubpages with a different microsite address.
For the pro package you get 1 custom domain and 10 domain sub pages.
For the ultimate package you get 10 custom domains and 10 sub pages per domain.
For more details, check at s.id/subscription and if you have any questions, you can contact the email helpdesk@s.id
