Here’s my understanding: A casino has two ways to know that a referal came from you:
1. When they visitor arrives they grab the affiliate code from the URL and set a cookie on the visitor’s machine with that code. This is pretty easy.
2. Or, they keep attaching the affiliate code to the end of every url as the visitor wends their way to the site. This is harder to do, and it fails to credit you if the visitor comes back later via someone else’s link, or by typing in the url directly.
I guess a casino could do both — #1 for most visitors, and #2 for those few who have cookies disabled.
My guess is that most casinos do #1, but that’s just a guess.
It would be very helpful to know what percentage of casinos use cookies vs. keeping the code in the url vs. both.
It would also be helpful to know what percentage of users have cookies disabled. Anyone know where to get that kind of data?
