Hello guys i have a question about something. I have a domain which represents one site(domain.com), on this domain i have 8 more sites(8 x sub.domain.com) that are sub domains. The domain is three months old and i have enough content on any of the sites to get organic traffic and everyone of those sites are doing well by themselves, but now i wish to register the site to web directories. I am wondering if when registering i should add only the domain or i should add every sub domain separately without adding the domain.
Just add the domain. Make the anchor text of your domain the same as the keywords you want to rank for.
