The first thing that we want to do is take a look at the total number of books that currently show up in Amazon’s search for the keyword that you are analyzing.
This is fantastic information for trying to gauge competition and saturation.
For example, if you were to search for the term “love” you would find that there are thousands and thousands of books that Kindle currently considers on the subject of “love”.
Ideally we have to find a keyword with at least 40 results and no more than 500 results.
