Amazon is a great platform to be an affiliate for. They have thousands of products to promote, that each pay from 4% through to 10% commissions.
This video shows how to become an affiliate with Amazon and also how to get your affiliate links to the products you want to promote:
Always follow their guidelines and don’t break any of their rules. If you do things right then you can remain an affiliate for Amazon for years and reap the rewards of the popularity of the website.
A great idea is to create a blog around one topic and add Amazon products from that niche. Then you can rank the website and get free traffic from Google. Then once the website is making money you can even sell it on Flippa.com for a nice lump sum.
Then rinse and repeat the process.
