Just like to add 1 additional "CON" to the list of Pros and Cons of Clickbank. Their rule on paying out the commissions earned. You must have 5 sales all from different credit card accounts before they will pay you what you have earned. That flat out sucks!. Affiliates work hard to get even 1 sale and because of Clickbanks rule, lose that money over time if they cannot get another 4 sales, the commission keeps reducing steadily if 4 more sales are not forthcoming. Clickbank has got to change that rule, which many feel is illegal!. A sale, is a sale, and the commission must be paid out. Basically, Clickbank is "Ripping-Off" affiliate marketers.
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.
