So I made 1x PBN backlink per day for five of my money sites for about 14 days until end of december '16. The keyword position from two of them started to drop heavily. I am talking about from #10-15 to #60-Nowhere. Now after more than 45 days they are still nowhere, it still seems like the rankings won't come back / rank in a higher position than before. On the three other money sites it had no impact atll all. They didnt lose rankings, but also they didnt improve. Anyone experienced the same? I thought about the PBN domains are penalized, but they are still in the serps and seem to be fine.
