How much money will I make?
Several factors determine the amount of income an affiliate can earn with a program. Are you selling a subscription service (such as website membership) or a consumable product (such as disposable contact lenses) that means repeat purchases and a more reliable income source? Does the company track repeat customers by storing your affiliate referral id with the customer's record in the database, or do they use the less reliable method of placing a cookie on the customer's computer?

Is this a fly-by-night operation?
Another concern of affiliates is how long the program will be around. There's nothing more discouraging than investing the necessary time to build a customer base and downline just to have the company go belly-up. If you have noticed indicators of a program's long-term success or failure, people who read your review would benefit from your insight. Even if you aren't 100% sure that a company will succeed or fail, it's appropriate to include educated guesses as long as you explain your reasoning.

Why should I choose this opportunity over that one?
It can also be helpful to discuss how this opportunity matches up against similar programs. In this case "similar programs" refers to programs that provide comparable products or services as opposed to programs with comparable compensation plans.

A final consideration of your review may be length. Some people prefer to read detailed reviews that delve into every aspect of a company. Others prefer to read short reviews that highlight only the most noteworthy pros and cons. Both style have supporters and can result in quality reviews. The important thing is to share information that you found helpful when you were evaluating the program.   Clay Mabbitt
