Earn Extra Income Online thru Affiliate Marketing

For the last one month I was taking paid surveys and so far the payout was not much. So I took the next step in making extra income online last week by singing up with Amazon and Commission Junction and others for Affiliate Marketing. So far I haven't had any luck, I think I need to blog more to attract traffic to my site.

I have signed up with the following companies:

• Amazon
• Commission Junction
• AT&T
• EBay

Let me know if you know any other companies that pays well and have lenient binding contract.
