Never used the disavow tool but I have a site I made when I was a noob I want to try and rank. It's metrics are 18TF 18CF 22DA 34PA 60RD. Unfortunately, I had no idea what I was doing back then, so I bought a bunch of cheap PBN links. I'm ranking like 150-250 for every keyword I'm trying. On-page is perfect, metrics of the site are great. Only issues are some over-optimized anchor text, and the crappy pbns in the backlinks profile. Would you disavow?
