Possible Duplicate:Ratio of No-follow & Do-follow Backlinks I've been playing with seomoz's tools and it seems like our site has a high number of nofollow links. from what I understand this is because a lot of blogs will make the links used in comments nofollow links, thereby not affecting our ranking? is this a problem and what can be done about it? 
high number of nofollow links bad?
seo;nofollow
