I have some friends of mine who have their personal blog . They don't use .wordpress or anything they have their own domain which they use as blog . So I was thinking on asking them or even paying them to post an article about my website (which is blackhat). Would this help me rank like PBN's would? Since they are my friends if anything goes wrong I can ask them to remove / edit the article. So yea I'm sure they will ask me money since I owe them some but I don't want to go into this if it doesnt help . What do you think ?Are blog backlinks good?
