Adsense by Google is a genuine and highly successful revenue making tool. All you have to do is create a website or a blog with genuine content. Place google ads on strategic locations throughout your site/blog. As traffic of your site increases, number of conversions increases and your adsense revenue increases. There are lots of people making money using Google Adsense. The only thing you must take care is that whatever you do, it should be according to the terms of service of google.

2.Revenue Sharing Opportunities - To maintain a website or a blog is a hectic task, if you don't have time and resource for that, then the best choice is to go for revenue sharing. If your content is good and worth reading, you can make a fortune from it. This site is among them.

3. Affiliate Marketing - This is also a good option and a very high paying one too. Here you will place affiliate links in your site/blog. If someone signs up you will get a predefined percent of the price of the affiliate product. It can come to even $50 for a sale of a single product!

4. Yahoo or Bidvertiser - These are other rival ad networks to adsense. These are not as good in terms of payout compared to google but is worth a try.

5. Guest blogger opportunities - There are various sites offering revenue for those who are ready to post in their blog. The terms may be in the basis of flat payout or on an adsense share basis.
