Here’s a category I found today when I sneaked around with Kindle Spy on Amazon:
Not bad, eh?
$5.56 on average per book, $1,724 average monthly revenue (estimated, of course). Low competition.
Could you write books for that category?
I bet you could, if you learned how to write about anything, and you can learn it when you get my book.
