That way, if you decide to write a review to promote it or send the affiliate link for the product's sales page to your email list, etc., you will have first-hand knowledge of how it works. This will help you to decide it the product has real value pertaining to your niche. I, personally, won't sell anything I haven't tried myself to be sure they work as advertised. Selling just to make money with no real value is a sure way to lose customers and ultimately destroy your business. Bad reputations are hard to get rid of once you get one, especially when there's money involved. With that being said, I hope you all have a great holiday season.
Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.
