Understand your demographics. Every affiliate will have their own target demographic. As the affiliate marketer, it's your job to understand your affiliates' demographics, and tailor your advertisements or reviews in such a way that that target demographic will be reached through your platform. Knowing, for example, the target demographic's age, interests, and average income range, will help you tailor your reviews and advertisements to that demographic.
Can you make money with affiliate marketing? The short answer is yes, affiliate programs can earn a extra money and even a full-time income from home. The long answer is a little more complicated. Like any home income venture, success comes not so much from what you choose to do to make money, but whether or not you do what needs to be done correctly and consistently.
