Oh Amazon, you so funny!
Owing to a cyclical book promotion, my second novel 'Dracula's Demeter' is currently being given away FREE on Amazon. When that happens, my books frequently hit #1 in many different categories (based on key words, algorithms, and blah and blah). Flattering, but not lucrative. Lots of downloads, no money. It's Free. And there are so many categories that reaching #1 is not only easy, it's hilarious.
One fellow self-published a book called 'My Left Toe'. It featured a picture of his left toe, and nothing more. Then he bought a copy of his own book; making himself a #1 best selling Amazon author in the category of Kindle store > Biology > Anatomy > Feet > Left Toe. But he was #1, AND he got paid for that sale.
I relate this story because I was amused this morning to see that this new book promotion has managed to make Dracula's Demeter #1 in three categories, including a category called 'Teen & Young Adult Survival Stories'. Dracula's Demeter is many things, but a SURVIVAL STORY is not one of them.
May all of your books (and book promotions) bring you like smiles.
