How to earn money from amazon?

First create an account with Amazon. Then Join Amazon Associates. They will guide you step by step, just follow the instructions. Then you will get html codes for any product of your choice or banners of your choice. Put those banners on your blogs or sites. Or better create an online store with a niche category of products and promote it. If you work on this you will get good results. But you need to be unique in your product selection and store design etc. You can also sell your own products on Amazon. You have to list them through your seller account. Also try MTurk, it is like doing tasks and getting paid. So you can choose the way you want to earn money from Amazon. It is up to you! All the best!
