I've been thinking about created a pbn for my site for a while now. The site domain is approx 3 months old and main keyword is about medium in toughness to rank. I have a few questions though: Would they have the same value if i used new domains? How many do you recommend for a medium keyword? Will i be able to see its value after a few days or will it take weeks to see increase? Could i push them onto another site the 301 them? Will this have the same effect as direct linking to money site?
