To use the Aruba Seo and Aruba Mix services your website must be registered with Aruba.
This is because the service provides new landing pages to improve the search engine ranking, which will be published on special third level domains associated to the main domain.
Consequently, during the order process, the system will check this: if the domain is not registered with Aruba the system will ask if you wish to register the domain or transfer it to Aruba and you can then purchase the advertising services during the domain order process.
If however, the domain is registered with another Provider and you do not wish to transfer it, you can request a project service.
Whereas, if you choose the Aruba Click service, your domain does not need to be registered with Aruba.
