Has anyone tried to use any tools or ways to find out best keywords for Amazon which tells you keywords people are searching for on Amazon.
Anyone can help me here? Thanks so much!

Use Long-tail pro for finding great keywords. Before researching keyword, you need to learn about keyword research. Cause you didn't ask here, if you know about how to research keyword. So at first learn about Basic Keyword research.
