MaxBounty pride themselves on the diversity of campaigns offered to their affiliates. They have over 1,500 programs ranging from gaming, to finance, and dieting, with options to receive your commissions as CPA (cost per action like making a sale), CPL (cost per lead), mobile, or PPC (pay per call.) Allowing you to structure your promotions in a way that works best for you.
Provide excellent customer service. Answer any questions buyers post as quickly as possible. Be professional and courteous. Positive communication builds your reputation with buyers and gets you return business. Also, package your product well and ship it out quickly. Allowing an item to become damaged or taking too long to ship can negatively affect your reputation among buyers. Wrap all items, especially fragile ones, in appropriate packaging. Commit to shipping items as soon as you receive payment.
Be sure to check what kind of customer support you can expect from your affiliate program once you have signed up. Do your research online and if possible, speak to other sellers using the program to get their thoughts. Can you speak to someone via phone or Skype or do you have to wait 72 hours for email responses? Be clear on this because trust me, you will need support at one point or another.
