Hey guys, I need some help please, as I am extremely confused. So I've set up a PBN on 30 different C class IP's, with good PA/DA expired domains and I followed all the proper rules to hide my network as much as possible. After posting a few 250 word articles to some money sites, I have realized that they have all got penalized. The only money site that didn't get penalized was over a year old. The money sites which got penalized didn't have the same amount of BL's from the blog network... some only had 2-3 backlinks and others had 12+. I am pretty sure my network didn't get penalized since when I search for titles, or content from my articles, it always pops as #1 for long tails. The penalty is not a manual penalty since added some of the sites to webmaster tools and nothing showed up. None of the PBN sites are in webmaster tools. Content is 100% unique. What's really weird is that the money pages actually start to rank and only got hit after two weeks of adding PBN posts, they didn't all get hit at the same time, some a week after the others. I only added 1 bl to the sites once indexed then every few days I doubled the backlinks, eg, 2, 4, 8 etc.. Here's what I think my be the reasons why it got penalized: Articles of 250 words or less trigger a penalty? IP addresses used banned by google? Maybe other people have abused them? Although I don't think my PBN would rank!? I have posted some articles in different languages over the PBN, could that affect it? Some BN sites have a few articles in different languages, though I dont see how this can be a concrete reason. I have used my kw in the title of my posts, maybe google can see overoptimized BN posts? Although even a site with 3 backlinks each to a different product got penalized, which is really confusing me. Thanks for all your help.
