I have a .co EMD that's been sitting in my account for a couple of years that I'd like to build an authority site on. I'm a little concerned about it, however, as it has 67 backlinks to Live Journal blogs, all as part of a copy and paste post. URL is linked directly to the keyword. The links are nofollow. I understand not having link diversity is bad, but help a newbie out... are these backlinks going to create problems when I try to rank the new site? Does it make a difference if they're nofollow?
