Hi there, To start with, excuse me if I'm sounding like a noob in this area. Have seen a lot of posts about tiering PBN sites. Say the more powerful sites will be on tier 1, and the less powerful PBN sites will be on tier 2. Now comes the question, why not directly have all as tier 1s? I mean, if they are quality PBN sites people will not realize their real purpose. And besides, they probably already have a ton of backlinks unlike Web2.0s that need the tier 2s and 3s to funnel link juice. Please advise. Thanks!
