Now we want to analyze each individual books ranking within Amazon.
This may seem a little bit backwards, but the lower the ranking the better the book is selling. For example, the rank #1 book in Amazon currently sells thousands of copies per day. But the #1,000,000 rank book in Amazon probably doesn’t even sell one book a day.
Again, you need to click through each individual book and find out what their rankings are. What you are looking for are keywords that have one or more books with high rankings.
This means that those books are getting organic traffic and making a lot of sales from the keyword that you are looking to rank for. Is a sign, that this first page is profitable.
