At the beginning, Murphy created her own affiliate program in house. She found that this process was a major time sink — she had to take the time to constantly monitor her program and remember to pay affiliates regularly. She made the jump on an affiliate network, where she could immediately access tracking, reporting, and payment systems (as well as instant access to affiliates who were more-than-ready to help sell her products).
Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.
It’s also important to research their payout structure. Not all payouts are the same and tier affiliate marketing often offer different payouts. Some might pay you on the first offer but pay you nothing on any upsells. Ideally, you should be paid for every transaction. In doing your research, you’ll find out which affiliate payout structures are the most profitable.
