I opened one thread few days ago asking about guest post,pbn,301 etc,but I didn't get answer on my main question so I will ask nicely here. Did you used guest post,did you bought some service or did you do it yourself somehow and did you see increase in ranking? I see 1 guest post 20$+,are they worth it and how much did they improve position of your website? How much guest post you bought? Please provide more details if you have them. Also if you have any tips or anything about guest posts feel free to write them. Thank you for taking your time to help me.
