Hello there fellow BlackHatWorld members. I've got some cash to reinvest and i have decided to build a PBN. Can you recommend me some guide to follow or something? 1. I've got some quite old domains with good BL profile which i'am not using and i want to use them for my PBN. I'll change the hosting and that stuff. Can i? 2. Is it good if all of my PBN domains are on the same hosting but different ips ? 3. What do you do about content ? I have plan for about 30 to 50 domains to start with and its impossible to maintain writing content for that much domains on monthly basic. Is spun content good for PBN's? I'm talking about human readable manual spun content. 4. What about the ratio about posts with links and posts without links? On what ratio should i keep up? I'm thinking to set this to 5/1... Have 5 posts with no links then 1 with link and so on... 5. Is it okay if i link from my PBN to multiple money sites? Or strictly one PBN per money site? 6. Do the domains needs to be strictly related to the niche or just the post from where i'm linking from? 7. Finding the good domains question. I've constructed a simple formula with the basics metrics for mass checking the domains if they are good or not. Its the following: ((DA+PA)/100)+(Number of BL/1000)+(Number of referring domains/500)+((TF+CITATION-FLOW)/100)+(PR/10)+(If already indexed +1 if not -1) -If the final result from the formula above is greater than 4 i think that domain is good. + Checking if the domain has over optimized anchor text or containing any adult or pharma content. Am i on the right path? That's everything that is unclear to me right now. I'm expecting to get it clear ASAP and get started with building my PBN. Thanks in advance.
