Niche Site Case Study Using a Private Blog Network

Wanted to share the success of one of my sites that I used my PBN to promote. There’s a lot of other factors that goes into this but the PBN was a big part at ranking this site. How do I know this? There was a time recently where I removed some of my PBN links and two weeks later the site dropped in rankings. I added them back and two weeks later the site came back in rankings. Crazy right? I don’t recommend doing this.
