I have a 40 different domains private network with 1 x pr 4, 8 x pr 3, 11 x pr 2, 9 x pr 1 si 11 x pr 0 .
Some of them old and with high authorithy . i have built them on some different ip's on some different servers .
I put an unique article per each of them and have marvelous effects. I have to say that i do not build more than 2 links per article.
The websites are very different one from the others, built in time on some different structures, with unique content , very well done.
The idea of this post is to respond to those which says private networks are dead. Get a life men !!! IT STILL WORKS....
Right now i am working to have aprox 100 different domains until tha end of this year.
