Online commerce solutions are not the only way to make money online.  The simple blog or content site you maintain as a hobby, might just be a solid source of income. 

Google AdSense

 Google adsense is one of the most popular forms of online advertising.  Google provides various ways for you to link to ads from your site. 

• Search Bar -
• Inline Ads -
• Tool Bar Ads -

One thing to understand before you rush to signup for google is that you will have to pay taxes on the money you make here.  Not that you shouldn't be paying taxes on everything anyways, but on the google tax page you'll find more information about the requirements.  Basically, they'll need you to fill out a W9 which will certify your taxpayer id before they start making payments to you.

Affiliate Programs 

 Although online casinos are one of the most profitable forms of online affiliate programs, there are many other affiliate programs as well.  Amazon, Target, and just about every major retailer has an affiliate program you can join.  The key is going to be knowing how to target your audience.
