kindly I need your help. I have created a blog with around 15 posts, the target keyword for each post was chosen carefully using semrush and LTP. I have also bought between 5 & 10 PBN backlinks for each post. After 2 month my rating hasnt changed except for 1 post which was appearing in the first page of Google after 2 weeks of creating it (so backlinks didnt make any difference). Does anyone has an explanation? I am starting to think that backlinks are meaningless.
