ars pays weekly with no holdback and pimproll and trafficcash are right behind them.

i'd say the most common payout is twice a month, sent around 5 - 8 days after the end of the period. so for money made from the first to the fifteenth, checks are sent out around the 20th or the 23rd.

personally i rarely promote a sponsor who pays only once per month, and even then i won't send as much traffic as i would to a program that pays more frequently. the sad fact is many of us in this business have been ripped off by sponsors - often sponsors we've had long relationships with.
