Five Perfect 'Spare-Time' Online Businesses

Take a look at some of the largest eBay PowerSellers and notice how they specialize in very specific products (iPods, cell phones, dog grooming kits, etc.). This allows them to leverage their efforts. A listing is created once, and money is collected over and over again.

Unlike information marketing, this business requires the handling of physical goods, but even that can be automated, so it shouldn't prevent you from considering this idea.

3. Affiliate marketing: This may possibly be the absolute laziest way to make money because it doesn't require you to have a product, make a sale or ever have any interaction with customers.

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?
