One of the disadvantages of working with a network is that they charge a commission, which is normally up to 30% of what you charge affiliates. For example, this is how it works: Brand C affiliate program might sell $1 million of clothing. They pay their affiliates 10% commission, so the total commission of the program would be $100,000. The affiliate network would then charge 30% override on this figure so the brand would pay $130,000. The affiliates would get the $100,000 commission and the affiliate network would get $30,000 override.
Provide contact information. It shows that you are a credible and experienced marketer. This is especially important if you're running your affiliate program through your own script. Unfortunately, too often affiliates work hard promoting and selling a program and never receive their commissions. You should always make sure that your affiliates are confident that this will never happen to them while they are working with you.
