Affiliate agreements can be entered into by any type of business, from sole proprietor to corporation. Affiliating with another company is a good way to promote your business and make more money by joining with someone who has a proven track record and a larger customer base. But before you join an affiliate program of any kind, consider these questions (from Leslie Truex, Home Business expert).
The support in there is really hit and miss, which can be a bummer, as the quality of response you receive can vary greatly depending upon who replies, and it’s seldom you’ll get much from either of the head muckity mucks. They profess to be active in the community chat, but often times it’s a lot of “hey, great job…keep up the good work and you’ll be making money in no time” kind of fluff. Be prepared to do some Googling when you have a question.
