We have really limited control over our categories. Amazon seems to decide, sometimes without much human thought. For instance, Threads: The Reincarnation of Anne Boleyn was Number 1 (really?) in the Religion>Buddhism category for about a year. I knew another author whose thriller was Number 1 in "Car Parts."giantpasta said:
I went to KDP and fixed things, but the last time I attempted to do that I was referred to a phone number. So, go to KDP, and find the phone number and call them.
Here's what I get. Let's explore it:
#1 in Books > Literature & Fiction > History & Criticism > Movements & Periods > Renaissance
#11 in Books > Literature & Fiction > Genre Fiction > Metaphysical
#48 in Kindle Store > Kindle eBooks > Literature & Fiction > Fantasy > Historical
History and Criticism? Not so much. I really belong under the following two categories. But if the sales rank moves up, that irrelevant category pushes further upward. So do the other categories (they display toward the bottom of your book page), but not as quickly. I can't believe that people navigate to this category, and select MY book over all others. Just as I really, really know that most people searching for "car parts" did not select a thriller over an air filter.
So, even 15 years into it, Amazon is still working out the bugs. But a phone call will probably help, if your book displays in a category that's really, obviously wrong.
