Hi all, i make a couple private blog network. From those cheap service and middle priced service. I won't mention who is who, you can found it if you are smart. Basically, what i saw is many of those service that i bought, had great PR. But their DA / PA and TF / CF are almost 0 Most of them have even very high / good review. Are this tell us , PR 4 with DA 1 / PA 1 , mozrank 0.00 will increase your ranking ? It did improve my ranking, but i bought too much service that i don't really know which work. But most of them actually are DA 1 / PA 1 , only some of them has better ranking. Check out the ss below http://i.imgur.com/BbDdnuU.png http://i.imgur.com/Na8uYjt.png What you guys think? The review is fake? or just people are too blind and just buy everything they could ? If someone like me had a personal PBN, which i has been using inhouse. All of them have valid PR/DA/PA/mozrank , and start selling on BHW marketing place. Will probably trash every service in there?
