Hello all black hat world members..I hope you're doing well..And merry christmas to all those who celebrate it .. I have some Guest Post backlinks from the authority websites e.g engadget, etc. I'd like to ask some questions here. Should I backlink to the Guest Posts? If I should, what type of backlinks should I build ? PBN, web 2 or what? Any help would be appreciated...Thanks a lot, guys..
