Hi all, First, I'm pretty new to this, so forgive me my ignorance but there's something I really don't understand. I don't know if I'm posting this to the right place, but it's related to AdWords too, and I couldn't find anywhere else to post it. *Admins: if it's in the wrong place, feel free to move my post to where it truly belongs, thanks. Well.. We have a running affiliate program, and lately I got a suspicious affiliate. He's using Google AdWords to advertise and makes his ads look like "official" ones. The problem is, that he's using our brand keywords, and it's clearly stated in the policy that it's strictly prohibited. However, the twist comes after this: I have noticed that this affiliate might have other affiliate accounts with our company and he even has fake affiliate ID's. What does that mean? Example: I go to a UK VPN and check google.co.uk for one of our "prohibited" keywords. Affiliate's ad comes right up. I click it. It redirects me to our website with his affiliate link. I go back to google.co.uk, enter the keyword again, get the ad again and click on it. After this, I get redirected to our website with a _fake_ affiliate ID (checked in our system, it doesn't exist). So right after clicking the Ad, the adwords link redirects to an adserver, which has 4 possible forwarding options. 3 fake affiliate ID links and one real. At this point it somehow reads data from my browser which is not a previously set cookie. (Could it be cache?) As far as I got it, this method is used to distract our attention from his "real" account, he's reading user data somehow, and if the script finds a customer "worthless" (since they have a cookie or whatever which is linking them to another affiliate) then he redirects them to a false Affiliate ID, to hide his prohibited activity. (Imagine if we would see that he refers e.g. 10K uniques daily with the same referer url, we'd instantly suspend his account due to advertising with prohibited keywords) Now he's paying for the misleading ads as well, while he's making thousands per week with the real one. Now the thing I'd like to know is this: how's he doing this? What I recognized: he's using a trackingpixel. But how can he read that I have visited the website and got the aff. ID cookie or not? Sometimes it only works from Safari, Mozilla is completely cookie and cacheless, while I'm using a VPN through a virtual machine, but I can only get the false ads.. Please help me out with this. I only want to understand the method, since I am not fully aware of it. The affiliate partner is getting his money.. Not. Thanks in advance.
