Given the breadth of this topic, we are just going to focus on just the aspect of keyword research for Amazon Affiliate Marketing.
That said, to start the keyword research process, you should already have a few Amazon products that you would be promoting as an Amazon Associate.
Create a small list of phrases that are relevant to the product.
One quick way to complete this task is by looking at the "Title" of the Amazon product listing and using the keywords you find.

Using the product title in the example above, these are some seed keywords.
Now that you have your list, take each phrase and use that to search for more Amazon keywords using our simple and effective Amazon keyword research tool.
Make sure to use each of the search mode; normal, precise, and broad.
Also, follow some of the same deep keyword search techniques discussed in the section about finding keywords for a Sponsored Products campaign advertisement.
