Question about new domain
 

I bought new domain milftube.tv, if im redirecting the domain to my site themilf.org its i can make a seo for it? for an example i promote the milftube.tv domain with backlinks it will help my domain themilf.org?

It might help a bit but why promote a domain that just redirects to other domain/site? I would rather build backlinks for themilf.org directly.

Will help more if you will build a custom site on your new domaine where to promote your old site !

thank you guys

I could be wrong but I believe using redirects is frowned upon by search engines, unless you use a 301 redirect.
