I've been running a campaign for a while now (drip feeding). I'm using Article, Blog Comments, Guestbook, Image Comment, Microblog, Social Network, Web 2.0, and Wiki. So far the it's made 1742 verified backlinks. What I'm wondering is, out of those 1742 backlinks it created for me, 852 of them are do-follow with only 148 being no-follow. 1. Do you guys think that is too high? 2. Would you have any suggestions for engines I should or shouldn't be using instead? (just for a general link-build with no tiers?) 3. If I do have too many do-follow links, is it still possible for me to save the URLs by sending some "no-follow" links to it?
