What we’re going to look at is one category here, e-business and e-marketing. When you click on that category, Clickbank automatically sorts the results by popularity. Popularity is basically how many sales that product is getting. As an affiliate, you definitely want to sort the results by gravity. Click on this little dropdown menu and choose Gravity. Gravity is complicated, but it’s basically how many different affiliates are making sales from that product. That’s important for you as an affiliate, because the more different people are making money from that product, that really shows that it’s a proven winner.

Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates".[30] Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
