Amazon’s “Secret” Kindle Category Passwords

Being a self-published writer is never an easy thing, it requires you to be half-writer/half-marketer to succeed, and the ever changing self-publishing world is full of all sorts of little tricks and traps. The traps are mostly about people trying to take your money for “services” you may or may not need, and the tricks are all about getting your book seen by the largest number of people. (And thus improving your chances of people buying your books!)

It doesn’t help that Amazon’s Kindle Direct Publishing platform is itself a giant labyrinth filled with ever changing rules and channels. One recent change is to their “Refine By” sub-categories, which can make a big difference in how your books are shown and presented.

Normally, when you self-publish a book on KDP you get to pick two categories for that book to be in. Say, “Romance>Historical” and “Romance”, and your book would be cataloged under those two categories and subcategories. The problem is that each category already has a certain number of titles in it, arrayed by their ranking on the site as a whole and other factors Amazon doesn’t reveal. So, for example, Romance>Historical has 24,420 ebooks in it at the moment, and Romance itself has 194,408 ebooks.

Good luck getting anyone to notice your nice new book in those piles!

Now, to make things a bit easier on authors, you also get seven “keywords” (which can actually be more than one word) that you can pick to describe your book. Traditionally more keywords could be added later by readers as well, and Amazon would use your keywords and theirs to add your book to a few extra “Refined by” sub-categories that you could only get to by Amazon employees adding your book to them.

Say, for example- Romance>Military. It’s a sub-category that exists, but they had to manually add you to that list if they thought you belonged and you didn’t have any say about it. Being included in that list could also be huge, because instead of competing with 195,408 ebooks the Romance category, your book might now be one of 3,128 books moving up and down within Romance>Military group. This could really help up your odds of being noticed and your books being sold.

And now, Amazon has changed their system. Instead of them adding you, if you use certain keywords when you register your book they act as passwords that automatically get your books added to these select lists! For example, if I included any of the the words “military, navy, army, soldier” among my keywords when I added my book to the Romance category my book would automatically be added to the Romance>Military “Refined by” sub-category. You can find a complete list of the “passwords” and more details on the KDP Selecting Browse Categories page, which you can then use to more accurately get your books into the sub-categories you think they belong to.

These will get your books into the “Refine by” lists you can see under the main category lists when you’re Browsing on Amazon, and those are definitely places you want to be to reach the most eyeballs. I’ve seen “Refine by” lists that have as few as 1 or 2 books- I kid you not! Can you imagine what getting your book onto a list that small would do for your chances of being noticed?

Of course, this is all about gaming the system, and I feel a little guilty talking about it. But then again, Amazon isn’t really hiding this, so why not take advantage of it while it’s still an advantage?

Good luck!
