When you recommend a user to any product (usually membership program or products which require recurring monthly payment), you earn a fixed commission when a referred user pays his next bill. Some of the companies offer a recurring commission for a fixed time (Let’s say one year) & many companies offer the same for a lifetime. It all depends upon company marketing policies.
Designed to create a huge amount of traffic at all times, these sites focus on building an audience of millions. These websites promote products to their massive audience through the use of banners and contextual links. This method offers superior exposure and improves conversion rates, resulting in a top-notch revenue for both the seller and the affiliate.
You may have heard of ClickBank, one of the oldest and most popular affiliate networks. A billion-dollar company, ClickBank specializes in digital products like e-books and software, as well as membership sites. If you are comfortable selling information and don’t want the management and administration hassles of “real” businesses, this may be a good starting point. Its commissions can be anywhere from 10% all the way to 75%.
Additionally, you must either include the following disclaimer adjacent to the pricing or availability information or provide it via a hyperlink, pop-up box, scripted pop-up, or other similar method: "Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on [relevant Amazon Site(s), as applicable] at the time of purchase will apply to the purchase of this product." In the above examples, "Details" and "More info" would provide a method for the end user to read the disclaimer.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
