The Commissions Report table gives you information about your sales. You can see on what date they were created what type of plan was purchased, and the campaign from which the sale has originated. If you only refer clients with your affiliate link directly without using campaigns, you will see that in the column "default". The last 2 columns show what the status of a sale is and what commission you can expect for it.
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.
