I'm just curious we got a system going on at our website, and I don't know how to do affiliate program to track I want other people to earn cash from it, but I don't quite know how it works, like is there somewhere that supports this. What I want is for every person that visits my site from a unique id from another site I'd like to pay the referring site a commission, or percentage of what I sale on my site? who can support something like this, my payments go through paypal?
You would either need to be with an affiliate network like ShareASale, CJ, LinkShare, etc. which can cost quite a bit. Or you can manage it yourself. You are looking for affiliate management software or just affiliate software. I have a link in my sig that takes you to a website where on it is a link that lists some of the top used affiliate software. I don't want to leave a direct link to it as it will be against these forums TOS.
You need an affiliate mamagement program. I'll pm you the link. It's free and does almost everything you need. pay per impression, clicks, sales and more. Easy to install. Tell me then when you use it how it works.
I've seen succesful affiliates that will run an affiliate program on a cost per lead basis such as signing up for an email newsletter as a way to aquire a list to then target for its merchant affiliate program's that it promotes. good luck
