Hi guys, back in 2015 I was ranking a tech site that work out quite well. I was just going through a list of old domains that i saved in a text file, so if I ever needed to go back to them id have the passwords / usernames to add posts. Now these were just made with the purpose for back-links kind of my first attempt at a PBN,but on more of a set and forget kind of view. I built up the pages created content posted my link and left it. Now I just ran a handful of these links through MOZ and found them having a DA of 97+ is this crazy? they are just simple sites how the hell did they hit that high?
