Affiliate marketing is the process of earning income every time you promote someone else's products or services. If you generate a sale for the company, you get paid. If you don't generate a sale, you do not get paid. As an affiliate marketer, you can earn limitless money. Affiliate income is not consistent. You'll to look at income from an annual basis instead of monthly. A decent affiliate can make anywhere from $10,000 a year to $400,000. A super affiliate can make upwards of $1,500,000 a year.
