In Internet marketing, an affiliate is a person or company which sends visitors to a website in exchange for commissions.

Affiliates can earn commissions in three ways: per click, per sale and per lead.
Pay-per-click programs have declined dramatically in numbers because of click fraud.
Pay-per-sale and pay-per-lead programs are still very common.
Each affiliate is given a unique link to paste into his or her website, so Commission Junction can track which affiliate is responsible for generating a sale.
Most affiliates own a website or several websites. However, some earn commissions by paying for advertising and sending the visitors directly from the ads to the merchant, others may generate revenues through email camapigns, (please be sure to appy or negative match list to any search campaigns)
