Hello I'm posting this to ask you guys if anyone has any suggestion on how I can find a whole PBN. There are many sites in my niche which I know are using PBN's as they are ranking on competitive keywords, but when you look at there back link profile all you see is low quality comment links. I know it's not possible to get a site on the first page with comment links in my niche. And some 8 month old sites don't even show any backlinks at all in Ahrefs, but still they are ranking first. Seems like my competitors are smart enough to block Ahrefs, OSE etc bots through the robots.txt or whatever way. I just wanted to ask you guys if you have any creative ways of figuring out a PBN that can't be traced by backlinks profile.
