I didn't have many websites, but they were generating enough money to keep me going while I am studying abroad. Last week on Saturday my multi-niche website got deindexed from google. I was ok with that because I still had money generated from the single niche domains. I was about to take action upon the main site in the near future. The sites are promoting black hat niches using cpa offers. Yesterday, I noticed a big decrease in visit stats on the cpa network I am using. When I check, I realize that my other websites are deindexed. Only one out of six is still up. And this is on the same host(as an addon domain) where one of the other website is deindexed. What is really troubling me is that all of the websites were on different hosts, 4 hosts for 6 websites and submitted on different google webmasters tools accounts. The backlink profile is different as well from one another. 3 of my websites have backlinks from a PBN, 2 of them are deindexed. The only one still standing has links from the same PBN. So I assume it is not because of the PBN. The PBN's are all up and healthy. One of the similarities between the websites from what I noticed, they all have a low Trust Flow and decent/high Citation Flow. Something like a 3 TF and 34 CF. Or 2 TF and 18 CF. Another one has 7 TF and 24 CF. 1. Is it possible to be related to this discrepancy in metrics the reason for the mass deindexing ? Another similarity is that I stopped creating backlinks on all websites in the same time, like 5 months ago. And I have lost many of the backlinks based on majestic stats. I also used GSA for creating backlinks apart from the PBN's and manually created WEB 2.0, but I used it with common sense, no churn and burn. 2. Could my stoppage in creating backlinks be a reason for deindexing ? Or the fact that I used GSA ? Other thing that I have noticed is that my articles posted on the deindexed websites are copied on pasted on other websites. Word by word on many websites, 5 to 15 websites. The articles are manually written by myself months or even years ago. 3. Does google really know that I was the first that posted the articles? Am I being deindexed for duplicate content ? The message in google webmasters tools under manual actions is: "Pages on this site appear to use aggressive spam techniques such as automatically generated gibberish, cloaking, scraping content from other websites, and/or repeated or egregious violations of Google's Webmaster Guidelines"
