How many sites do you need in a PBN?

[anush]

For real? is there any blog/article covering that study that shows PBN links helped pages rank well?

Nobody talks about it openly. And why should they?? Would you, honestly??

The thing is majority of the sites rank because of PBN links. These BS of PBN bad and all are a fuss that has been created by so called SEO experts who have know idea on how in reality things are.

If you get into closed circles of the real webmasters then you will know the truth.
