I own a company for teams Ex myteams.com . A team registers and they get a site at team1.myteams.com. Content on each sub team site is mostly unique and I have several back links on each to the main site myteams.com.
I also provide them with a unique URl team1.com will show team1.myteams.com.
So couple questions
As far as SEO should i be pushing the team1.com url or team1.myteams.com url?
Is a link from team1.com or team1.myteams.com better for my site, their site or both
How many back links should the sub sites have?
Thanks
