What are the terms of the program? Is there anything I need to be aware of that would make a program not worth it for me. For example, Amazon Associates does not allow you to put your affiliate links in emails. If your main method of communication with your audience is via email, Amazon might not be a good fit for you. Wayfair, for example, does not allow their affiliates to post affiliate links on Pinterest or any other social media site. If that’s a strategy you rely on, Wayfair might not be a good fit for you.
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". 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.
