There is no certification needed. However, we do recommend that you learn as much as possible about what it means to be an affiliate. Fortunately, there is a lot of information out there to help educate new affiliates, including podcasts, blogs, webinars, research reports and much more.
Although you do not need training, merchants do have the power to approve or reject affiliate applications. Some are looking for specific qualities in their affiliates and are more selective about who they choose to accept into their program. Often, merchants will not approve sites that are sexually explicit, violent, violate international property laws, advocate discrimination, promote radical religious or political views, or advocate or promote any illegal activities.
