It helps to discover opportunities in niche markets.

    How Most People Use Kindle Spy

    Let's go over the typical ways KDSpy v5 is used, and in the next section we'll cover how to choose bestseller categories.

    1) Checking Keyword Profitability

    Let's say I want to publish under the seed keyword paleo diet.

    I went ahead and (1) typed this see keyword phrase in the Amazon Kindle store and got my page 1 results. Next, (2) I clicked on the KDSpy browser extension to run Kindle Spy:

    KDSpy V5 Keyword Analysis with daily sales
    KDSpy Pulls Info Directly From Any Amazon Keyword Search

    Doing this will give me valuable data for the top 20 ranking books, including their:

    • the # of books ranked in search results
    • the Kindle book title,
    • the page count (some find the page numbers column useful when starting a book project),
    • book price
    • estimated sales for search results,
    • the estimated total monthly revenue,
    • the number of reviews per book in the top 20 search results,
    • and the bestseller ranking (the closest this number is to #1, the more the Kindle is selling).

    Also, notice the bottom-right section of the KDSpy browser extension. There's a traffic light section:

    Kindle spy - somewhat useful features
    Traffic Light System – traffic lights measure Popularity Potential, & Competitors

    I don't recommend paying much attention to the traffic light system. The traffic light bubbles are more of a suggestion that KDSpy pulls from it's Amazon integration.

    The Total Monthly Revenue  of the top 20 is a rough guesstimate and more of a sales revenue potential metric in my experience.

    So, how does this data benefit you?

    • You no longer have to manually check each book's sales page – instead KDSpy v5 compiles it in rows & columns in its browser extension dashboard,
    • you can see how the keyword phrase is being used by the competition at a glance,
    • you get a good idea of how profitable your book idea is by checking the average monthly revenue column,
    • it displays the number of reviews.

    The Word Cloud: A Somewhat Useful Feature…

    An extra keyword results feature the Kindle Spy browser extension has is the Word Cloud.

    KDSpy Word Cloud
    Keyword Suggestions

    This feature can potentially reveal keyword variations, a new book idea, and niche opportunities that you might've missed.

    It reveals the most-used keywords that authors use in their titles & subtitles.

    2) Author Page Analysis

    Another way Kindle publishers use KDSpy v5 is by spying on a competitor's author page. Analyze anyone's author's page!

    Let's examine a self publisher's author page: Steve Scott.

    authors kdspy
    Author Page Analysis: KDSpy v5 shows Kindle book AND paperback book data (see the two tabs in the image above)!

    Notice that KDSpy v5 filters Steve's (or any author's) Kindle books by lowest (best selling) Amazon BestSeller Ranking (ABSR) to highest ABSR (worst selling).

    Steve's self-published books are great. He's an expert at his craft and marketing efforts. He uses his blog, email list, and optimizes for Amazon's search engine to make passive income sales from his books.

    His average monthly revenue (Kindle and paperback books) has surpassed six figures in monthly revenue. I recommend checking out his self publishing course.

    Other things you can draw from this KDSpy author analysis are the keywords the author is using in his/her book titles & subtitles.

    3) Track Your Competitor's Performance for 30 Days Plus

    Another cool feature KDSpy v5 has that no other Kindle software does, is keep track of other author's book sales ranking.

    You do this by simply clicking the “T” while you're spying on a potential keyword (or author profile):

    KDSpy Other Book Competition Tracking
    Competitor Research & Keyword Analysis Feature Reveals Niche Opportunities

    After you click on the “T” your KDSpy dashboard will switch to the book tracking feature:

    Track Sales Rank of Any Book
    Track sales data for Kindle books, Kindle paperback, or hardcover books!

    Click on the Green “Track SalesRank” button and KDSpy will switch to it's tracking page where you can track your competitor's book bestseller rank for 30 days.

    KDSpy Tracking Feature Day 1
    Tracking page reports the book sales rank at 42.89k for the first day!

    I find this book tracking feature to be one of most valuable tools when using Kindle Spy as it can give you idea of potential sales volume.

    You know a book is making good monthly revenue when its bestseller rank is below 100,000. It's even better if it's consistently 50,000 or below!

    Below is the book tracking feature mapping out the daily sales and sales rank for a competitor's book over a 30 day period (the new version of KDSpy works just the same). I wanted to see how this book would do after a month and KDSpy's sales tracking feature delivered.

    kindle spy summary benchmark
    The average sales rank for 30 days of tracking this competitor was 87K.

    The 30 days sales rank performance of a book in your niche is only part of an equation, but this feature validates there's money to be made in said niche.

    When you don't have a Kindle publishing tool like KDSpy v5, you'd have to keep track of how well your competition is doing on a spreadsheet or paper daily…

    Now that we've covered the 3 main ways authors & publishers use Kindle Spy, and the data KDSpy provides, let's cover categories!

    The #1 KDSPy Feature That Helps You Become a Best Seller on Amazon

    Why Should You Care About Your Book Categories?

    2 words: more exposure.

    Exposure is the name of the game when it comes to Kindle Categories, and KDSpy v5 improves your chances of selling more books by increasing your click-through-rate.

    An Attractive Orange Badge Next To Your Book

    Imagine you're doing some niche research in a cookbook niche, and you come across some books on the first page of results, and they're doing are doing well.

    kindle books with best seller logos

    2/3 books above clearly stand out more in the image above (put aside the red arrows).

    Enter… The attractive orange “Best Seller” badge that yells “Click me!” to prospective buyers.

    best seller logo

    Best sellers have the Best Seller icon by their book, usually has the upper hand in the rankings.

    The simple orange badge leads to higher click through rates for your books and signals to Amazon's algorithm that your book should be ranked higher.

    You can get a Best Seller sticker by being the #1 best seller in your respective ideal book category.

    How to Do Book Category Research With Kindle Spy

    Step 1 – Figure Out Your Competitors' Categories

    KDSpy Category Analysis - ebook category

    As you can see, the example book above is an Amazon best seller in the category Native American Cooking, Food & Wine, and is also ranking #1 for the keyword Instant Pot Recipes Cookbook (at the time of writing this article).

    Going to the book's page, I can see that the book is a best seller in 3 categories.

    line category research feature

    Let's choose the third one on this bestseller list. We can access this category page by clicking the blue hyperlink above.

    book cover of Amazon Best Seller list

    This example book is sitting firmly at the #1 spot, out of many books, for this category's best seller list.

    Step 2 – Analyzing Category Pages with KDSpy

    KDSpy can analyze the top 20 books and more on any best seller category page – including both Kindle books and physical books (when applicable).

    When I click on the KDSpy browser extension, this is what I get for this example:

    KDSpy v5 Category Analysis for Kindle and Books
    Reverse Engineer the Bestseller with Category Ranking

    If you hover over the red “i,” the extension will tell you how many sales are required in 24 hours to be #1 in the category!

    Sales Require to be Best Seller via KDSpy

    Notice that KDSpy compiled the top 17 books in the category and provides important key performance indicators about these books.

    The Sales Rank column is a good indicator of how profitable a book is. The more books under 100K – the better.

    But, things are not as black and white. The higher-performing books there are in a category/niche, the more competitors there are fighting for that #1 spot (typically).

    This is why I recommend adding the maximum number of categories in your KDP dashboard settings.

    KDSpy also shows you the average sales rank, average monthly revenue, and more:

    KD Spy Parent Category Analysis

    Notice that the profit potential (Avg. Monthly Rev. and Sales Rank) are much better than the prior category, but the competition is strong. You can tell by the Price column.

    The Next Steps are to choose the best categories and add them to your KDP account!

    Final Thoughts on KDSpy

    Kindle Spy v5 is just one of the many market research tools in the Kindle Publishing world. It's not going to break or make your Kindle publishing business – no research tool will.

    However, KDSpy can give you an upper hand in the research process (choosing categories & keywords wisely) and in the search results as an indie author, self-publisher, and/or business owner.

    Wesley Atkins is the creator of Kindle Spy, and I've seen some KDSpy version updates over the years. 

    These free updates and accepting user feedback  give users confidence that this software will be around for a long time even when Amazon has algorithm changes.

    You can't beat the price for the lifetime access KDSpy browser extension which is a low $47!

    Does KDSpy work with both PC & Mac?

    Yes, and it uses very little disk space! It's easy to install, Mac and PC compatible, and available for Google Chrome and Mozilla Firefox browsers.

    If you're looking for a competitive edge in search results and a much better chance of your book(s) getting the best seller badge, I recommend you use KDSpy v5.

    Alternative Software to Kindle Spy

    Kindle Spy v5 search tool, by Wesley Atkins, has made its mark as one of the best Kindle publishing software applications on the market. It's keyword analysis section is one of the best. 

    However, you might've heard about Publisher Rocket (formerly known as KDP Rocket) created by Kindlepreneur.

    Both self publishing software share common features, but also have features the others can't do.

    For instance, Rocket can't track a competitor's book monthly ABSR performance.

    On the flip side, Kindle Spy doesn't provide estimated Amazon Searches Per Month for keywords and search suggestions . Kindle Spy is also not a keyword research tool for AMS ads – these are the few page spying limitations with KDSpy.

    Both publishing tools are good for your self publishing empire and tool belt. Learn more about Rocket in our Publisher Rocket review (example tutorial included). I lightly touch on Kindle Samurai in that article…

    I recommend giving both search tools a try if you're in the book business. Each software tool has a money-back guarantee and cost a one time payment.
