I think there are several elements that affiliate programs deemed as a quality one:
1) Obviously fast and timely payments (no hassle would be nice!)
2) Experienced management- solid team of AM’s and execs that know the business
3) High converting brands/ competitive payouts/ high converting marketing materials
4) Trustworthy stats, reporting and tracking
What program(s) are you working with out there that you feel can deliver these to you consistently?
