Here’s the least you should know.  As an advertiser, the fees are typically less than the big 3.  There are usually less publishers, you won’t find any fortune 500 companies, and many of the affiliates are “mom and pop shop” products.  You’ll also find clickbank type networks that sell software.  I personally am always skeptical of putting a large amount of my budget or energy in any of these programs, although I’ve occasionally found a gem or two. I’ve also gotten burned.  Remember that there tend to be less affiliates in these programs, so you could find a diamond hidden in the rough. But, there’s no guarantee that any product is going to sell, so if the quality of the product isn’t there,  you could also lose your shirt.
