1. When is it good to start making PBN links? I mean ones from my own private network. Should I build normal diversity links first (web2.0, profiles, wiki, article, press release etc.) to gain a little bit authority first? 2. What about the anchor diversity? Should I use only exact match keyword anchors on PBN posts or how do you handle this? I think I am really struggling on that, because I think sometimes I over-optimize the anchors and it is doing more harm than charm.
