I'm getting some super weird rankings hitting me for 4 different websites all in the same niche targeting the same keywords on separate hosting accounts. I've been working on building out these websites for the past month, and one of them I built a week ago. Let me back up a bit and talk about the first one, I built it on june 27th, built a couple wordpress blogs to it, added some content to those wordpress blogs and some social signals. Please note that I buy all my social signals from blackhatlinks.com (I'm not affiliated with them, I'm just stating facts). It indexed pretty quickly on its own and things started rolling for that website #1 and it started ranking on the 5th page for one or two keywords. This niche is a totally wide open niche, it's literally three people trying to rank for these exact keywords, me and some other random two guys. One guy is ranked #1 for the main keyword, the other page 2 and he sometimes pops up for page 1 at the bottom. I started building my PBN from a cool guy here on bhw and everything was going swell. I build out 10 pbn domains in a few weeks time, didn't link out, and let the pages naturally index with 3-4 pages of content on each. I started linking out to my first site in the middle of july and got things going to page 2 and sometimes bottom of page 1 for all my keywords. Now fast forward to yesterday all my keywords on all 4 websites took a nose dive all to page 5-7. Now I built 4 sites in total for this niche, on separate hosting accounts, and they all have private whois information. How could this keep happening? I'm at a complete loss of words on how this logically keeps happening. I know its a thin-content penalty, but why were all 4 of my websites hit at the same time? One of my competitors is right there with me on the 5th - 7th page for all his keywords as well. The other guy, he's still ranked #1 for the main keywords. His rankings have been rock solid for months. Could this guy be mass-reporting my sites/his competitors? I use seperate WMT accounts for each website and I use my mobile phone's web browser to accessing them + my 4g data. I dont use google analytics anymore, I honestly dont use any type of visitor tracking on them period. None of this logically makes sense, its driving me up a wall trying to get it figured out. I think shit through logically and nothing makes sense here in this case besides the guy mass-reporting me.
