"Love the Kindle Spy software to help me see trends in the industry"

Sharon Hamilton Kuods

Love the Kindle Spy software to help me see trends in the industry, as well as verify how I am doing, in a snapshot graph, compared to other authors in my genre. I also use it when I'm contacted by authors I don't know, or when I want to learn about what successes others are having that I can learn from.

"The only software tool we use for niche and keyword research"

– Mikkelsen Twins (Kindle Publishers)

Why do over 54,085+ fiction & non-fiction

– AND hundreds of WSJ, NY Times & USA Today – bestselling authors use KDSPY Pro?

Because many have grown their platform, book sales, and income by leveraging the research tools and competitor insights gained with KDSPY.

KDSPY sits in your browser as your book research assistant

Unlike isolated software applications buried on your computer, KDSPY sits in your browser and becomes your 24-hour on-demand research assistant when you're browsing Amazon.

Research Assistant

Reverse engineer the bestseller categories
in a single click

When you want a detailed breakdown of any of the 25,000+ Kindle, book, or audiobook categories on Amazon, click on KDSPY from within your browser. In seconds, you'll know the competitive landscape of that category, the potential estimated profit you could make there with a first-page listing, and you'll have a detailed breakdown of each book's important metrics.

See how many books you need to sell in 24 hours to rank #1-20

For Amazon's algorithm to pay attention to your book, you must sell a certain number of copies within 24 hours to achieve a category ranking. Once you've identified an ideal category based on revenue potential, simply rolling over the red 'information' icon with your mouse reveals the estimated daily sales you'll need to compete for a first-page position.

Discover the popular trends & keywords in any book category

What better way to find bestselling niches - and get ideas for your next book - than by modeling what's already working for other successful authors? KDSPY shows you the popular trends in any market, reveals the bestselling niches to go after, and even gives you a word cloud to help you write a compelling book title.

Analyse keywords in-depth for profit and ranking potential

Perform any keyword search in KDSPY and instantly receive its profit potential along with hundreds of additional (A-Z) keyword suggestions – all exportable for AMS ads. Additionally, you'll get competitor counts and their estimated monthly revenue. Our keyword analysis feature drills down even further to reveal the likelihood of ranking on Amazon for it as well.

Spy on other authors & publishers and model their bestselling books

KDSPY can analyze any author page and tell you in seconds all their statistics. Just a single click will show you the sales rank of all their Kindle, paperback, hardcover, and audiobooks, their estimated sales, and total revenues broken down by individual book type.

Track the sales rank & revenue of any book over 30 days

Keep track of as many Kindle, paperback, hardcover, and audiobooks as you'd like with our book tracking feature. KDSPY pulls the sales rank of your competitors' books automatically every day, then displays their performance in chart form, along with their estimated daily sales and monthly revenues.

Supported Amazon Stores

Rebecca Hamilton used KDSPY to create over 400 bestselling authors

New York Times, USA Today, and Wall Street Journal bestselling author Rebecca Hamilton always had a knack for marketing. However, she used to spend countless hours on market research for herself and hundreds of her author clients. 

Then she found KDSPY, which took out all the guesswork and freed up more time for her to focus on other areas of her career. Using KDSPY, she was able to help over 400 of her author clients hit the "New York Times" and "USA Today" bestseller lists.

"Now nearly every book I publish is a bestseller"

“KDSPY is hands-down the most valuable software I have right now for my kindle business. I have been publishing books on Amazon for since last fall, but things never really took off until I started using Kindle Spy. This software made it so easy for me to quickly see profitable niche markets in my areas of interest and now nearly every book I publish is a bestseller! In the next few months, I will be making enough money to finally quit my day job – yahoo! I actually use KDSPY for more than just finding profitable niches to write books on. I also use it to follow my own books. I use it to see, at a glance, how my own books are doing, so that I can gear my marketing efforts towards the ones that need it, and celebrate the ones that don’t. Honestly, as a publisher, writer, and business owner, KDSPY is the first thing I check every morning and the last thing I check every night.”

"Opened my eyes to the untapped potential"

I am quite new to Kindle and found it quite difficult to understand how to do proper research and understand what categories to focus my energy in. KDSPY cuts out all the legwork and in a matter of seconds you get a complete and detailed spreadsheet with up to the minute average sales revenue, amazon best sellers rank, number of reviews and total revenue for your chosen niche. It's invaluable and certainly opened my eyes to the untapped potential awaiting kindle publishers. Another plus is the "word cloud" feature of the top keyword in the titles per niche. That alone is a goldmine and we all know the power of a popular eye catching title! However, despite all these features and benefits, Wesley's constant hands-on backup support in answering any queries I had about using KDSPY and his willingness to listen to feedback sets this product apart from others I have brought. If you are looking to grow and rapidly expand your Kindle publishing empire, KDSPY will get you there faster.

– Mike Moreu, Childrens Book Illustrator & Author

"KDSPY is probably one of the most valuable tools an indie author can utilize. It’s exactly the app I needed to uncover all the info—accurate data, not guesses—on which subgenres sold well and why."

"This levels the playing field in so many ways. Now it's much easier to compete and create a product with more than an educated guess. My wife and I love KS4. It is easy to use and the pdf that goes with it could be sold as a product but it is free. Thanks!"

– Anthony Kollar, Self Published Author

Got questions?

Here are answers to some of the most common questions we get about KDSPY.

Does KDSPY work on Mac and PC?

Yes. KDSPY is a browser extension compatible with both PC & Mac. And the good news is, installation takes less than 4 seconds no matter what computer you’re using – seriously!
(Note: KDSPY will not function on iPads, Tablets or Smartphones).

Can the results be exported?

Yes. Absolutely. KDSPY will analyse all the Kindle, Paperback or Hardcover books in any category, and give you an export of the results in under 29 seconds. KDSPY also provides an export of the word cloud, keyword results, author analysis and tracking data.

Does this work on any browser?

KDSPY will operate on Google Chrome, Mozilla Firefox, Microsoft Edge, Opera & the Brave browser – on an Apple, Windows, Chromebook or Linux system. Due to the declining popularity of other browsers, it will unlikely be supported on others in the future.

Can I install on multiple devices?

Yes. Your purchase comes with a DUAL license. Which means you can install KDSPY on up to two (2) devices that you own personally. Many people today use a desktop and a laptop, so we'd never ask you to purchase again to use KDSPY on an additional computer.

Do I get future updates to KDSPY?

Yes. If you lock yourself in today for the insane price of just $69 (one-time fee) – that’s all you will ever pay. You will get ALL future fixes & feature updates to the software. We take user feedback very seriously. In fact, we’ve made over 329 updates and rolled out over 20 advanced features since KDSPY was released in 2014.

Does this work for fiction authors?

KDSPY was originally created for my own "non-fiction" publishing business. However, being able to research multiple fiction categories, keywords and competitors with the speed of KDSPY – will save you countless hours of research time when trying to see which genres may be the most profitable to enter. It's why 65% of our customers are in fact, fiction authors.

Does this work internationally?

Yes. KDSPY will work anywhere in the world to pull data from one of the supported stores. Initially, KDSPY was created to pull results from the largest Amazon marketplace; the US. However, due to popular demand, KDSPY Pro now supports results from specific stores in the UK, Canada, Germany, Australia, France, Italy, Spain, India, Japan, Mexico & Brazil.
