PBN links bring 90% of my link juice. The other 10% are web2.0, directories etc. The point is, these 10% make a lot of work and bring little effect. I would like just to use my PBNs. Lets say I have a website with just 5 heavy PBN home page links and no other links. Will that raise red flags? I am not talking about anchors here, for sure I have to be careful with these.
