I currently have a PBN about 50 websites, all in a specific niche made around 1 money website. In last month or so 6 PBN websites got deindexed and 2 of them got partially deindexed (homepage deindexed). I am linking with my 50 PBNs mainly to 4 different pages on my money website. What deindexed websites have in common that all of them are linking to the same page on my money website. There are still about 6 PBN websites left that are linking to that specific page and are still indexed. All the other PBNs that are linking to other 3 pages are still indexed. Just a coincidence? About deindexed websites: I host all PBNs on different cheap hosting. 2 different domain registrars, all have privacy They are mix of dropped domains and domains purchased at auction Different Wordpress themes They all have 2-3 posts - Not enough? Some of them also linking to other authority websites in that niche They all block bad robots with WP Robots Txt plugin They all have All In One SEO plugin in common I did exactly the same for all other PBN sites that are still indexed. I also put one of those deindexed domains in google webmaster tools and there aren't any messages. Anyone got similar experience?
