If you've created a PBN (Private Blog Network), what's the best way to utilize it to promote your money site? Do you link from the front page? From inner pages? How many links per blog to the money site? Also, what's the lowest level PR you should have in your PBN? Is PR1 too low? PR2? Obviously, the higher the better but is having some PR1 niche links bad? Thanks for any guidance.
