How to tell if a high ranking site is using PBN? I tired using ahrefs & majesticseo to see what they're doing, but the report only shows approximately 100-200 links. Nothing spectacular or outstanding. So could they be using a PBN? Or maybe, they are sending links to a buffer site then 301 to their money site? If that's the case, will it show the 'buffer site' in the report, or all the backlinks that are being 301 in the report also?
