I am just starting with CJ. I noticed with my ebay affiliate that if I need a different PID for each website. what if I used the wrong ID on the wrong website? Would I get created since it came from my account?
I just dont undrstand why they dont let one number be the person, why several would be required. just curious.
I suppose they do that for better tarcking (it's better for you as well because you will have better stats which of your sites sells more/better )
It's primarily for your own tracking. You don't HAVE to use different PIDs if you don't want to do so. You will still get commissions even if the PID is from the original domain and it's used on your other domains. The PID is primarily for your own domain tracking, and the SID is for even more specifics.
