PBN courses & good sources to read

Hey. Can someone share a course for PBN creating? Or maybe any kind of good related sources to read about PBN.

First consider that PBN are solely a Black hat technique, not white hat (for the subforum where you posted this)
Secondly, consider giving a check to purush/inspireme labs content (@vishyjames):
https://www.blackhatworld.com/seo/the-no-nonsense-guide-to-building-your-pbn-in-2017.944503/There is some more videos from him in platforms like udemy
Although I feel you should be reading a lot in the forum about this and try to join the pieces one by one once you have covered some basics.

Also check threads by @splishsplash as he knows a bit about PBNs.

just search on the forum, there are many threads about how to create PBNs.

Visit market place you can find many threads for PBN.. Also refer google and youtube for tutorials for reference..
