I didnt like the domain I was using for a forum so I bought a new domain and now Im redirecting the old domain to the new forum. Question is I ranked pretty high for a few good keywords, should I keep building links to the old domain for those keywords? Will it do me anygood since its juts redirecting? If this is possible can I just by domains and redirect them to my main site for SEO purposes? Will the rediracting domain still be indexed?
