hey guys, i want to establish my own PBN step by step. First i will buy around 10 domains to start blogs and get more after the 10 blogs have high DA and PA. How can i increase the DA of my PBN ? Shall i buy some high DA and PA links for them ? Will the DA drop after i stop buying links ? because i can not afford to keep buying links. Sorry for the stupid questions, i am newbie.
