Affiliate programs
They pay you a percentage of the sales you generate for them, or for each visitor you send. This is one of the best ways of making money on the Internet. You don't have to spend time and energy creating your own product. And some of them pay 50% commission. A good recomensdation I would tell you to join is Chapaa City Affiliates. I have made a good income out of it.
Google AdSense
This is one of the easiest ways of making money on the Internet for small and medium sites by displaying relevant, text-based ads from Google AdWords (Google's own advertising program) and receiving a share of the pay-per-click payment. Check out what I have been earning - its easier than you think.
Banners
They were one of the first ways of making money from hobby Web sites, however they are not so popular now since most surfers don't even look at them. In fact, the click-through rate (the percentage of visitors who actually click on a banner) has steadily dropped, from around 5% 4 years ago to less than 0.5% now.
In the Traffic-Building volume of Make Your Site SELL! 2002 (the free ebook describing all possible ways of making money on the Internet), banners are called #1 "Time and Money Wasters." Save yourself months of poorly spent time. Read this essential manual first.
If you have highly relevant, cleverly designed banners, you can beat the odds. However, you need relatively high traffic to actually make more than pocket change. In fact, most banner advertising companies prefer to only pay for actual sales (even click throughs are no longer attractive, since many people click through because they are paid to, and not because they intend to buy anything).
FreebiesUnder this category are things such as free lotto tickets and various games where you can win prizes. Often, these are implemented as pop-ups and are much more annoying than banners.
