I made an Amazon Review site last month and has been stuck on page 3 for my main keyword which only has 600 monthly searches but the page 1 is half filled with other Amazon review sites. Using my free Ahrefs account, I saw that the number 1 result for that keyword has only really weak backlinks but still manage to be on top. I tried making Web 2.0s but only 3 or 4 are even indexed on Google. Besides that, I haven't done any link building but only concentrated on content and making my site look nice. I'm getting around 10-20 visitors a day not from my main but from relevant product keywords. Anyways, what is the next step I should take to get my site to the front page? I have been thinking about this for days and the only thing I came up with was buying links or making my own PBN. I was thinking of buying PR 6 backlinks here from the marketplace. Any advice is appreciated!
