In the last couple of years, several high-profile brands and influencers (Warner Brothers and the Kardashians, to name a few) have come under scrutiny for failing to disclose paid advertisements. Along with this enhanced focus from the FTC comes the new General Protection Data Regulation (GDPR) regulations, ensuring affiliate marketers will be more focused on compliance and transparency than ever before.
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.
