I've been looking into the traffic and conversion of my course and in the sources it shows a site called anonymz. I clicked on it and it just shows a site that says there you can block the referer when a vistitor clicks a link on your homepage and i've had 3 visitors from there. Does anybody know what this is? This source differs from the rest. Thank you in advance.
The only reason to send links through there is to hide where the link came from. Probably originating from some pirate site if I had to guess - whoever is using it doesn't want you or Udemy to know about them. But if it's only 3 visitors, it's probably not worth worrying about. It's possible it's nothing nefarious and just someone running a website who is overzealous about privacy.
