Hi, I'm currently in a situation and I need your perspective to consider should I do it or not. The thing is, my post was stuck at #2 for a while. I have done many kinds of links (all safe). However, I was wondering whether should I boost the tier 1 with high DA/PA, TF/CF PBN links? I know the benefits of tier 2 and what they capable of. However, I still afraid of getting penalize by Google when doing so. What is your perspective/opinion? My situation: Here is my tier 1: Unique article 700+ words Some are authority links, like Engadget, Huffingtonpost, or LifeHack Some are normal niche related sites. What should I do? What would you do?
