There are three basic types of affiliate program payment arrangements:
- Pay-per-sale (also called cost-per-sale): Exabytes's affiliate program is an example of a pay-per-sale arrangement. In this arrangement, the merchant site pays an affiliate when the affiliate sends them a customer who purchases something. Some merchant Web sites, pay the affiliate a percentage of the sale and some pay a fixed amount per sale.
- Pay-per-click (cost-per-click): In these programs, the merchant site pays the affiliate based on the number of visitors who click on the link to come to the merchant's site. They don't have to buy anything, and it doesn't matter to the affiliate what a visitor does once he gets to the merchant's site.
- Pay-per-lead (cost-per-lead): Companies with these programs pay their affiliates based on the number of visitors they refer who sign up as leads. This simply means the visitor fills out some requested information at the merchant site, which the merchant site may use as a sales lead or sell to another company as a sales lead.
There are a number of other arrangements as well. Basically, a company could set up an affiliate program based on any action that would benefit them, and then pay their affiliates based on the number of customers the affiliates send them who perform that action.
Additionally, there are a few pay-per-impression affiliate programs. Companies running these programs, also called pay-per-view programs, pay affiliates based only on the number of visitors who see their banner ad. Usually, this sort of arrangement is not structured as an affiliate program, but simply as a traditional advertising program.
The advantage affiliate programs have over traditional advertising is that in an affiliate program, an online merchant only pays its affiliates when it gets a desired result. Traditional advertising, such as the ads you see on TV and a lot of the banner ads on the Internet, is relatively risky for the advertiser.
They spend money on advertising based on a guess of its effectiveness. When an ad brings the company more money than it spent on that ad, the ad is a success. If the company makes less money than it spent, it has to swallow that loss. With an affiliate program, an online merchant only pays its affiliates when things are working. Because there's much less risk to the merchant, it's a lot easier for Web sites to join affiliate programs than it is for them to attract advertisers.
