Introducing KDSPY v4

The Fastest, Most Accurate Way To Identify 'Bestselling Kindle Niches'

'Reverse Engineer' The Kindle Categories In Seconds To Find Your Next 'Bestselling' Book Idea. Here's How:

Reverse Engineer The 'Best-Selling' Categories With A Single Click

Browse any category in the Amazon Kindle marketplace and – in the background – KDSPY will 'automatically' reverse engineer the best sellers. When you want more information about a Kindle category, just click on KDSPY and in mere seconds, you'll know the landscape of that category, the potential profit you could make here – PLUS a detailed breakdown of each book's performance.

Another Click Tells You 'Exactly' What Your Next Book Topic Should Be

Once you've gathered data for the category you're interested in ... another click will give you a word cloud that calculates all of the words that the best selling books use in their titles. What better way to find best selling niches and get ideas for your next book than by modelling what's already working for other Kindle publishers. KDSPY shows you the hot trends in any market. Reveals the best-selling niches to go after – and even shows you the words to use in your book titles...

Analyse "Niche Potential" With The Kindle Search Results Analysis Feature

Once KDSPY spits out your next "best selling" book idea, why not run a few searches on Amazon around that niche and add a 2nd layer of confidence before you commit. Do any search in the Amazon Kindle Store and KDSPY will instantly tell you the potential in that niche. It doesn't get any quicker than this to research niche markets...

Spy On Self-Published Authors & Swipe Their 'Best-Selling' Topics

Ever wondered how much money other self-published authors are making? Wonder no more. KDSPY will analyse any author page and tell you in seconds all their statistics. Just a single click will tell you the best-seller rank of all their Kindle books. The estimated sales and revenues per month. PLUS, see their total sales revenues for all their books combined.

Track Your Competitors Book(s) Performance Daily Over 30 Days

Want to make sure the book topic you've chosen is a sure-fire winner? Well, just like with a website where you'd track the effectiveness of your competitors in the search engines, monitor their banner ads or their PPC ads – with KDSPY, you can keep an eye on as many Kindle eBooks as you'd like with our book tracking feature. Pull the SalesRank for all your tracked books every day and display their rank in chart form.

Frequently Asked Questions

Still sitting on the fence? Here are answers to some of the most commonly asked questions...

Does KDSPY work on Mac and PC?question

Yes. KDSPY is a Chrome Browser extension that is compatible with both PC & Mac. And the good news is, installation takes less than 4 seconds no matter what computer you’re using – seriously!

Can the results be exported? question

Yes. Absolutely. Every last piece of data that KDSPY pulls can be exported. KDSPY will analyse 100 book results and give you an export of the results in under 29 seconds. But that’s not all. KDSPY will also allow you to export the word cloud results to help you laser target your niche and potential title. Confused? See the videos at the bottom of this page.

Does this work internationally?question

Yes. KDSPY will work anywhere in the world on one of the supported Kindle stores. Originally KDSPY was created to pull results from the largest Amazon marketplace; the US. However, due to popular demand, KDSPY v4 now supports results from specific Kindle stores in the UK, Canada, Germany, France, Italy and Spain, India and Japan. If I get enough requests, I will also consider adding other countries too.

Do I get future updates to KDSPY?question

Yes. If you lock yourself in today for the insane price of $47 – that’s all you will ever pay. You will get ALL future updates to the software for life. And I plan on making a lot of updates based on user feedback. Heck, we’ve made 12 killer improvements since this was originally released in July 2014.

Does this work for fiction authors? question

KDSPY was originally created for my own “non-fiction” publishing business as the main benefit comes from identifying patterns from the best sellers. However, being able to research multiple fiction categories 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.

Does this work on any browser?question

KDSPY is programmed to work on Google Chrome and Mozilla Firefox. Due to the declining popularity of other browsers, it will unlikely be supported on any others in the future.

...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 upto the minute average sales revenue, amazon best sellers rank, number of reviews and total revenue for your chosen niche. Its 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.
