Affiliate marketing is a fantastic way to make money online. If you're not familiar with the term then here's a brief explanation… As an Affiliate, you will promote other peoples products and receive a commission for any sales that were made from clicking on your links.
For example, this blog Single Man's Paradise has affiliate links. If you book a hotel, join a dating site or buy a product from Amazon then I receive a small commission from these companies. It's not much, but if you have decent traffic then those sales can add up to a nice monthly salary.
The sky is the limit when it comes to affiliate marketing. If you have an extremely popular site (or group of sites) you can make very good money. What I love about affiliate marketing is it's hassle free. I don't have to worry about shipping products or dealing with customer service. All I do is promote the product.
The thing I don't like about affiliate marketing is it's not a real business… Despite the freedom, you are still working for someone else. Break their terms and conditions and you're done.
You're basically a freelance marketer for companies and they call the shots. They also make the real money while giving you a tiny cut. Your goal should be to create your own product that others can promote.
