Another important benefit is that you only market a product as long as it is worthwhile. You an drop any product you like at any time. Of course, the merchants can also stop using affiliates as well.
You can be an affiliate marketer for almost any product, from computer memory to 40-inch plasma TVs, from baseballs to car components. You can also market digital products, and this is one very attractive way to go – in fact, generally it is the most lucrative because the costs of producing digital products are very low. Therefore, the commission levels are high – often 50-60%, and some are 75%. With physical products, the commission levels are more like 5-10%, but the products may be expensive.
