Referral fees aren’t just for the products you recommend. Perhaps the coolest thing about the Amazon Associates program is that you receive credit for any sale associated with your affiliate link for 24 hours. So, if a customer visits the page of the product you recommended, but then goes on to purchase five more eligible items during that same visit, you will receive a portion of that entire sale.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
Products are now put in a category. The commission will be based on the category each product has been placed in whether or not the category is correct. For instance, I had a sale for a child riding toy tractor. Instead of it being in toys category which would have only earned me 3%, it was actually placed in lawn and garden category which I then actually earned 8% instead.
Now most affiliate programs have strict terms and conditions on how the lead is to be generated. There are also certain methods that are outright banned, such as installing adware or spyware that redirect all search queries for a product to an affiliate's page. Some affiliate marketing programs go as far as to lay out how a product or service is to be discussed in the content before an affiliate link can be validated.
