An e-commerce merchant that wants to be able to reach a wider base of internet users and shoppers may hire an affiliate. An affiliate could be the owner of multiple websites or email marketing lists; therefore, the more websites or email lists that an affiliate has, the wider his network. The affiliate that has been hired would then communicate and promote the products offered on the ecommerce platform to his network. The affiliate does this by implementing banner ads, text ads and/or links on their multiple owned websites or via email to their clientele. Advertisement could be in the form of articles, videos, images, etc., which are used to draw an audience’s attention to a service or product.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online.

When beginning your affiliate marketing career, you’ll want to cultivate an audience that has very specific interests. This allows you to tailor your affiliate campaigns to that niche, increasing the likelihood that you’ll convert.

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.

No matter what method you select for generating your online income, there's one very important thing to understand.
