How To Master Kindle Keywords And Amazon Categories For Books

Find Your Kindle Keywords And Amazon Categories For Books

Many ebooks and software programs can help your ebook sales by using Kindle keywords.

You might think that there is some magical secret that every self-published author needs to know to get ebook sales.

You can do basic keyword research without an Amazon Kindle keywords tool. There is no mystery or magic to adding keywords to any Amazon product to improve your search results and selling on Amazon.

The truth is that Kindle ebook keywords are easy to find, use, and implement for your ebook. But yes, some keyword tools can do a better job for you.

Select the best Amazon Kindle keywords and categories

It is the most vital step in helping you to sell your ebooks.

There is no magical secret formula for doing Amazon keyword research.

KDP even gives instructions about getting your book title into additional Amazon categories on the Kindle Store.

In addition, there is an in-built Amazon keyword research tool for you to use.

Amazon Search is a basic Kindle keyword analyzer, and it is quite useful for finding long-tail keyword ideas.

As you know, when you list your ebook on Kindle, you can only choose two categories.

But do you know that you can get your book into more KDP categories (or product listings) to help readers find your book?

You can do it by using carefully selected Kindle keywords.

Like anything listed on Amazon, optimizing your product pages is key to getting more sales.

Let’s start by helping you find great categories and seven relevant keywords for your ebook.


The free method to choose Amazon Kindle keywords

You need to know how to discover what words people use when they are searching Amazon for things (ebooks) to buy.

Amazon’s search engine is by far the most efficient way to sell anything on Amazon.

Let’s say your book is about vampires, so of course, you have this as your seed keyword.

But would people who are looking for a vampire book to read search by using the word vampire? Not necessarily. So how can you find out what they might use?

You can find real Amazon keyword search terms that Amazon suggests by using its search box.

These are terms that real shoppers have used when looking to buy a product. In this case, a new vampire book or ebook.

The image above shows the phrases, or in keyword speak, long-tail keywords, people have used on Amazon to find vampire books.

Long-tail keywords are always more than one word, and often three or four. You can use these word phrases for each of your Amazon keywords.

Now select one or two of the suggestions from the drop-down list to use as potential long-tail keywords for your book.

Perhaps in this example, vampires and werewolves and vampires and witches might be good choices as your search terms.

You can keep searching for different words to find more search term suggestions that you can use.

Just remember that a one-word keyword will be highly competitive, so avoid them.

It is much better to choose long-tail keywords for your seven KDP keywords.


The best way to do Amazon keyword and category research

If you have a lot of titles or you want to fast-track your keyword research with real-time data, you might want to investigate Publisher Rocket.

It is a pro tool for Amazon book and Kindle keywords.

When you use the Amazon search bar for your free research, it restricts you to only ten suggestions at a time.

It can be very slow going to find a good list of potential keyword phrases. You also have no way of seeing Amazon’s keyword search volume.

But with Publisher Rocket, you can access the entire real-time Amazon database. You can find the best seven long-tail keywords and two book product categories for all of your titles.

You can search by sales data, price, search volume, product title, and even your competitors.

With any keyword research, you want to find keyword suggestions that are reasonably high volume but have low competition.

If you are a regular Amazon seller, there is also data available for Amazon PPC keywords to better position your Amazon Ads.

Publisher Rocket is especially useful to help you find competitive keywords for fiction books as well as low content paperback books.

By doing an in-depth analysis of competitive books listed in your genre, you will certainly find better KDP keywords and categories. It will help your book rank higher and sell better.

Do you have a lot of titles already published on Amazon KDP?

You might also consider using KDP Wizard. It is a free tool to manage and update all of your data, categories, and keywords across multiple titles.


Research your Amazon keywords

By using the two methods above, you do not need to spend a cent on software or how-to ebooks.

You can get extra categories and find genuine KDP search keywords for your book.

All you need to do is carefully select your seven precious keywords from both sources. Then you will have your ebook best positioned for buyers to find.

You can also experiment, change, and refine your keywords and categories at any time. All you need to do is change them in your KDP dashboard and re-publish your book.

So no, there is no Kindle keywords mystery. Your best free Amazon keyword tool is Amazon search.

Everything you need is at your fingertips and for free.

For more detailed information about how to choose Amazon keywords, read our article about KDP keywords for Kindle ebooks and books.


Get your book in more than two categories for free

You can get your book into more categories by assigning special Amazon keywords for specific products. There is a set of specific search query keywords for books.

All you need to do is follow the instructions given by KDP on its help page: Selecting Browse Categories. (See update note below.)

Scroll down the page and select your genre. If I choose Mystery, Thriller, & Suspense, I get the following list of keywords.

I have my ebook in the Mystery, Thriller, & Suspense category. But I can have it appear in several sub-categories by using the nominated keywords.

For example, I could add murder or police and have my book appear in more sub-categories. Therefore, it will be seen by more people and compete against fewer other titles in these sub-categories.

This same list of keyword choices is listed for all major genres, from romance to science fiction.

So now, you can get your ebook or book into more than the standard two categories or genres.

I have managed to get some of my ebooks in up to five sub-categories by using this simple trick. It is a great way to improve your Amazon listing.

Important Update Note: 

Unfortunately, Amazon has deleted the link to the list of browse category keywords. You can now only choose from the BISACS headings in your KDP settings for your book.

However, if you used the method above in the past, your extra categories still appear for your book.

The only option now is to ask Amazon KDP to add your extra categories.



Whether you use the free method or pay to access the real-time Amazon database, both will help you sell your books.

The most crucial point is carefully selecting your two categories and seven keyword phrases.

With these, you can increase your book’s discoverability.

If you can get your book in a high position for less competitive search terms, your book will be seen by many more potential book buyers. They will have a genuine interest in your book’s theme or subject.

As far as publishing advice goes, it is the most time-efficient and cost-effective way to promote your book.

    Thank you for this informative article with links to helpful resources. I have heard this before but really didn’t know how to figure it all out. I even purchased KDP Rocket and have searched some terms but didn’t know about the high volume/low competition. I’m going to get to work on this for each of my books and hopefully they’ll rank higher and get discovered.

    What do I do if Amazon has no category for an ebook? I have an ebook about guns, specifically, Why gun control laws will fail. I’ve tried it in several categories without success.
    Also, I am new to this and did not understand googles ppc, I lost several hundred dollars and discovered I was actually selling for other people as I used googles keyword tool. Most of the keywords which came up were very expensive or I was penalized for using googles own keyword list which they showed to me.
    Now I will never use google for its keywords as I still don’t understand it.

    I feel really dumb, but I’ve searched the kindle direct browse category page over and over and cannot find out how to access the list of categories with recommended keywords that appears in your screenshot. The link to ‘keywords for category assignments’ on the Browse Category page only leads to the ‘Make your book more discoverable with keywords’ page.

    When I google for the exact page in your screenshot I can reach it, and the breadcrumbs say it is a subpage of the Browse category page, but I can’t figure out how to get any other lists of keywords.

    Thanks for any advice you can give me!

      Let me investigate, Pat. Like all online companies, Amazon is often changing certain aspects. It’s impossible to know when and what, though. But I’ll update the post if I discover anything has changed.

      I can see the problem now, Pat. Amazon has deleted the link to the pages listing the extra category keywords. However, you can find them by doing a Google search.

      Enter this phrase exactly. amazon keywords for book categories

      It will then list the results to the category keyword lists for you.

      I will update the article later with some direct links.

    Nice basics that really make a difference especially on the amazon subcategory keywords. Had been missing out on that for so many years…

    Under KDP instructions for keywords, it states no need to use repeat words as you have already set them in your category.
    But when I follow your instructions to put in my genre in Amazon search to see the common searches. All the suggestions have the category words tied in forward and backward.
    Should I use these as written (with the repetition) in my keyword boxes?
    Thanks, Julie

      Yes, Julie. You need to use the additional keywords Amazon suggests to gain extra categories.

    As one of the terminally thick, I must say thank you for not giving up on us! Being of an age where nothing to do with computers comes easily to me, it is great to read some instructions that even I can tackle. I’m going to give this a try and hopefully open up whole new avenues of readers! Ah – who am I kidding? Half a dozen new ones would be nice, but this knowledge will stand me in good stead for future blockbusters. :D

    Seriously; thanks again!
