Here are a few ways you can sell stuff online with affiliate marketing to make money for yourself.

Affiliate Programs. Getting paid to sell other people's products is the quickest way to get going that I have found. Affiliate marketing has been around for over 10 years now and many people look at Amazon.com as one of the first companies to sell products this way.

You can make money selling clicks such as with Google Adsense. You can make money selling leads with affiliate programs like Max Bounty. You can make money selling products. One such way is to sell information products like you would find at ClickBank.

Another thing you can do is affiliate program directories like AssociatePrograms.com or Commissions Junction where they have compiled some of the best products to sell in one place.

Certainly network marketing also offers some great residual income for repeat business on a monthly basis. Many MLM companies will set up your customers and distributors on auto-ship and the products they order go out like clock work every month. When they do you make a commission every month just like clockwork as well.

Selling memberships is also profitable. This can be done through both affiliate marketing as well as network marketing. Getting paid over and over for making one sale is called residual income. Products that can be accessed online and offer value to your customer are great to sell. Paid memberships fit this description. Subscriptions on how to run a home business, personal development, paid newsletters on every subject imaginable, website hosting, autoresponders, and just about anything you can think of, offer you a chance to create residual income.

Two tier programs where you get paid on the sales of people you recruit work great for paid membership programs as well. Of course network marketing falls into this category and can even be better because you can make money every month on the sales of a large group of people.

The key with most paid subscription programs is you make a little bit of money on every sale. The first month this may not amount to much. The second month it can be more. In a year it can be quite a lot. Kind of like compound interest if you know how that works.

Free ways to make money online abound and it is really a question of deciding what interests you and what income model you want to use.
