On the surface, it appears that you can only choose 2 categories from within your KDP account, right?
What if I told you that most authors don’t realize that with a simple hack they can have their books placed in up to 10 different categories!
The only caveat is that while you can have a total of 10 categories, they can’t all be eBook categories. So, if you have a print book, you can request that it’s included in 2-3 categories and your eBook in the other 7.
Here’s how to do it:
First, your book must be currently published and live on the Kindle marketplace. This means you would have already selected 2 categories when you completed your listing.
Now, find your book’s ASIN number and write it down.
Next, find all the categories you want your book to be included in and write down the entire category string. Double-check that none of your requested categories are ones that need a specific keyword as found here: https://kdp.amazon.com/en_US/help/topic/G200652170
If it is, you can add that keyword into your book listing as one of the 7 you’re permitted and your book will appear in that category in 24-48 hours.
If the category isn’t one that’s shown on the page above, it’s time to log into your KDP account and click the Help link.
Choose “My Books” as your support option. Under “Select details”, choose “Update information about my book”.
New options will appear. Choose “Browse Categories”, and then “Update my book’s browse categories”.
I personally choose email as my preferred method of contact, but you can have KDP support call you. It isn’t necessary, nor does it usually have any impact on getting listed faster.
In the contact box, type in the following:
I am writing to request that my book: ASIN NUMBER HERE is added to the following categories:
ENTER FULL CATEGORY STRINGS HERE (one at a time, in list format).
Remember, a category string looks like this:
“Kindle Store > Kindle eBooks Entrepreneurship > Startups”
Amazon will respond within 48 hours confirming that your book has been added to the new categories!
Also, keep in mind that if you ever edit your book listing, you don’t have to worry about your categories resetting. Your book will always stay in the additional categories unless you contact them again and ask to change them up.
