Hello. On September I bought a domain that was indexed correctly on google and I was going to use it as PBN. I have planned many filler articles up today. Today I was going to drop my first external backlink to my money site. Before of that I did a research on google... and all the pages were missing. Any of filler articles I published during this months was indexed. So I added my site to a fake google webmaster account... And it's not spammed. It doesn't have any penalization at all. Something weird I notice though is that this PBN has 2.243 not found warning from the previous owner. This link are all .pdf files so I can't do much... Is this the cause? A build this site with Drupal and it's the first time I use this cms... Maybe I messed up something with this cms?
