This is essentially a “referral” business, or as one of my book contributors likes to call it, “passionate recommendations.” Basically, you can get paid a referral commission just for sending people to sites (or vendors) that are set up to pay affiliate fees once a sale is made. The vendor does all the selling, fulfills the purchase and handles any customer service issues–and you just collect your check..not bad!
Some people choose affiliates based on who or what is paying the highest commissions, and that certainly is a viable option. Most people opt to choose products or goods they are passionate about so that the process is much more fun and engaging.
Insurance and credit card companies pay high commissions for referrals that convert to customers ($40 to $150 and up), but the competition is fierce. It may pay well, but is this something you’ll enjoy doing for the long haul?
Alternatively, you could take a look at your hobbies and other things you enjoy and see which affiliate programs are a good match. As always, do your research to verify the viability of your market. A good place to look for ideas (and downloadable products just waiting for an affiliate) is ClickBank.com.
