Affiliate programs are a great way for merchants and Webmasters to generate revenue from their Web sites. Affiliate programs work -- serious affiliates make a significant monthly income from their efforts.

But Webmasters and merchants participating in affiliate programs often face administrative and legal issues. For example: Are my referrals tracked accurately? Will I get paid on time?Will I get paid at all? And most important: Will the company stay in business?
