If you already have an Amazon affiliate account and you build a new website you will need to add it to your Amazon affiliate account settings.
This is really important since Amazon has really strict rules regarding spamming. So many people that are into affiliate marketing go about it the wrong way and spam their affiliate links anywhere and everywhere. This just gives affiliate marketing a bad name.... and if you do this with your Amazon links you will lose your affiliate account with them.
The only place you can put your Amazon affiliate links is on your own websites that you have listed with Amazon. Don't send them out via email or share them on social media or leave them in comments on someone else's website.
This video shows you how to properly add your websites to your Amazon affiliate account.
