Hostgator.com also pays a hefty amount for 20+ referred customers.
Hostgator uses CJ in addition to its in house affiliate program. Some people might find that to a good option.
so I think I need the one who pay more for referered.
I highly recommend you to think beyond the size of the commission. After all, as a referrer/affiliate, you're only as good as your reputation. You should try and choose a very good host, with a well paying affiliate program.
