Learn how it works. An affiliate marketer embeds her own unique affiliate link in her web page or blog. This link does not have any impact on customers, and it does not alter the price of any products/services being offered by affiliates. However, any time the customer makes a purchase after clicking an affiliate link within a specified time frame, the marketer gets a commission from that sale. How much you earn will depend on each affiliate's prices, commission percentages, and the number of sales you're able to initiate on a weekly or monthly basis.
An affiliate marketing program is a lot of work, and in most situations there's a lot of competition so you're not going to be bringing in money immediately. Business owners and entrepreneurs suppose that all you need do is setup a site and choose an affiliate to associate with and then just let it run its course. But according to Three Ladders Marketing, only 0.6% of affiliate marketers surveyed have been in the game since 2013. That means that affiliate marketing takes time and effort to build and make money.
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.
