Hi,
I am an Amazon Affiliate/Associate and doing it successfully for many years. I know almost all stuff related to this field.
Please note that to earn passive income from Amazon Affiliate program, you need to create Product Review websites where you should publish high quality reviews/articles and link to Amazon products within them. You need to attract Search Engine (Google) visitors to your website to earn actual money.
If you can get at least 100 visitors per day from Google on your Amazon review website, then you can earn around $10-$15/day ($300-$500/Month). To get 100 visitors per day, I suggest 100 high quality and lengthy reviews on your website.
I have done many such websites for me and for my clients.
Please ping me if you need more information.
