KDP Keyword Categories

I want to explain two different things in this KDP Keyword Categories discussion.

First of all there are 2 KDP categories when you do your Niche and KDP Keyword Research.
That’s the search bar on Amazon.

kdp keyword categories

In the search bar you have all kind of different categories but we KDP publishers focus on two different ones.

  • All (All departments)
  • Books

95 times out of 100 you want to focus on the All category.

Why is that? 

Because that’s where people mostly search on Amazon.
Not many people do selected research in the book category so you are better off searching in the all category.

The second thing is Amazon KDP Keyword Categories.
What is that?

You seem when you target a certain keyword and niche you also want to put that in the right category? Why is that?

Here is Book Bolts explanation.

“Having your books listed in the right categories on Amazon is very important to help you make the most sales possible. When you publish a book through KDP, you will notice that in the category selection section there are way fewer categories than what you will see while browsing through books on Amazon”.

And did you know that you can list your books in more Amazon KDP Keyword Categories than two? Do you want to know how to do it?


I know there is alot to take in after this article but there is actually a lot to benefit from using a KDP Keyword Research Tool like Book Bolt. But as I told you in this article the free tools work the same way and sometimes they are even more detailed when you put them all together.

I really recommend reading my guide on the 8 Best Free Research Tools For Amazon KDP so you understand the basics behind keyword research and niche research. It not just something you can do out of the blue and if you don’t do it you will not succeed on Amazon KDP
