I watched a vid on youtube. I wont link it here because I know this guy is not too popular on BHW and I dont want to promote anybody here. I found some of his ideas interesting though and would like to discuss here. What he says is that most PBN sites have no traffic or other signals (eg social signals). For that reason they dont look like real sites for google which a bit devaluates their link power. What he therefore suggests is to build social signals to the PBNs and even build web2.0 properties. Attached a screenshot I took from the vid. Whats your opinion on this?
