What is KDSpy?

KDSpy is an application you can install on your Google Google Chrome, Mozilla Firefox, Opera & the Brave browser. This app allows you to more quickly and easily find Kindle keywords on Amazon. One of the most important tasks as a publisher and where you will spend most of your time. I sometimes spend days upon days searching for golden book titles. Anyone who already has some experience with publishing knows it’s not easy. You need to find keywords that meet specific criteria. In other words, they need to be profitable and not have overwhelming competition.

Once you find good keywords, you can order your books from a ghostwriter company like “The Urban Writers.” I highly suggest you check them out; they provide awesome content for a reasonable price. Make sure to use your coupon code “JA5” to get a 5% discount on your orders.

Why Should You Use KDSpy?

If you don’t know what a keyword or book title is, then check the example below.


“Yoga” is a keyword or a book title. Whenever customers want to look for a product, they type whatever they want in the search box. For instance: Affiliate Marketing, Mindfulness, Cryptocurrency, etc.; these are all keywords. If someone likes Yoga and wants to purchase a book to learn more, they type “Yoga” in the search box and voilá! A list of about 20 relevant books appears.


If you wanted to see if “Yoga” was a good keyword, you’d need to analyze two things:

  1. Profitability
  2. Competition

Now to analyze both things manually would be very time-consuming. Imagine doing this process hundreds upon hundreds of times. In my case, throughout my career as a publisher, perhaps I’ve analyzed about 10.000 keywords. Of course, I entered several niches and didn’t research all these book titles at once. Otherwise, I would go nuts, and soon I’d be internalized in a mental hospital. So, don’t get scared, lol! Perhaps, you can find a good keyword after you analyzed about 100 to 200 keywords.

Let’s see how you can do this process manually.


I’d need to open the six first books on different tabs, then go to each of them and analyze their data.


I’d check the “Best Sellers Rank” and see if it is below 100.000. In this case, we have one with 34.490, which is pretty good. This rank is based on the number of sales a book is making daily. The more sales a book does, the better it is ranking. For example:

The book with a “Best Sellers Rank” of #100 sells more copies each day compared to the positioned at #10.000. Thus, you want to see if the first six books for a particular keyword are below 100.000; This indicates they are selling well on Amazon.


So, if you were able to rank your book on one of these first six results, there’s a chance you would make money. Considering, those books are already profitable.

Furthermore, you also want to analyze the competition. You do this by checking the number of reviews of each of the twenty books. If the first page of results, all the books have beyond 100 reviews, don’t waste your time. Most likely, those books belong to authors. As a publisher, you’ll struggle to get that number of reviews.

Anyway, analyzing all this info manually is monotonous. You’d need to continually open a bunch of new tabs to analyze each new keyword. Even worse, considering you would need to do this process repeatedly for hundreds of book titles. Now that is where KDSpy comes in with a big freaking bang!
Just with one click and boom…


You get all this important information compact in a single window, where you can easily analyze without needing to waste time opening multiple tabs. No more hassle, no more pain, everything you need in a sleek window. You can quickly see if a keyword is profitable and not too competitive in a matter of seconds.

KDSpy Is Inexpensive

Besides all, KDSpy is also damn cheap! You get it once, and you get it forever. KDSpy has no monthly fee, nothing! I have been using this application for three years now without worries. I can’t imagine how many times KDSpy has paid out and shortcutted the time I would otherwise waste searching for Kindle keywords.


You just need to purchase KDSpy once for $59, and it has a 60-day money-back guaranteed. It’s a sure deal, how could you ask for more? So, click here and start using KDSpy today!

How to Use KDSpy?

Now let’s go into more detail about the multiple features that come with KDSpy.

Feature 1) Keyword Results


Book Title: Here, you can see all of the 20 books listed and their respective titles. You can also click on the “Pull Results” link to get more results. Hover on the small calendar to see the publishing date of each book; This gives you an idea if the books published there are recent or not. If they were freshly published, then new books are hitting on the front page of results.

Page(s): Here, you can see the length of each book. This info lets you know the length you need for your book. Imagine that if all books are around 300 pages, you should publish one with about that length.

In this case, “Yoga,” the books’ lengths are all over the place. One has 1496 pages, while another one has only 21 pages. Meaning, you can get away smartly with shorter and cheaper books.

Est. Mo. Sales: This value estimates the total number of sales per month for each book.

Est. Mo. Revenue: This value is based on the price and number of sales one book has per month. Once again, this is an estimate, so it isn’t an exact revenue.

Reviews: the number of reviews each book has on Amazon. One of the most important values you need to analyze. Based on this info, you can see whether a keyword is too competitive or not. As a reminder, if most of the books listed have above 100 reviews, then it may be too competitive.

Sales Rank: you may get an idea if the books listed are selling well. At least, you should have the six first results below 100.000. I also always check the Sales Rank first before wasting time with competition. If a keyword isn’t profitable, then it’s game over. All the rest doesn’t matter!

Avg Sales Rank: This is the average Sales Rank of the book on the front page of results. I usually like to keep this at about 200.000.


Popularity Potential Competition: Ha… I must mention these three lights. People always ask me if I pay attention to them. My answer is “No,” I never look at these lights. I always check the profitability and competition following the criteria I explained. Anyway, if you’d like to learn more about analyzing keywords, read my other tutorial here.

Feature 2) Keyword Analysis

The second feature is similar to “Keyword Results.” However, it comes with a coloring option, which allows you to see some aspects more clearly. The color red indicates what is hard, orange, average, and green low. You can see red on most books’ reviews, meaning it’s tough for publishers to compete with these books. Let’s check a few other new options.


KWT: Keyword on the title. In other words, if the main keyword in this case, “Yoga,” is on the title of the book. When you are optimizing your books, you should always include them there; This helps your book more easily rank for that search term.

KWD: If the keyword is present in the description of a particular book. You should also include a few times there.

Rating: Indicates the total rating for a particular book.

All other options are similar to the ones I explained before.

Feature 3) Word Cloud

The third option is not a great way to find alternative keywords. This window shows the most common words used on the book titles and subtitles of the first page of results for “Yoga”. The boldest ones are the most frequently used, meaning #1 st Yoga, #2 Your #3rd Poses #4th Mindfulness, etc.


I can quickly look at these results and combine several words to get new keywords like:

  • Mindfulness: this may be a good keyword
  • Yoga+for+beginners: I just combined beginners
  • Atkinson
  • Yoga+Techniques

I could go on and on. Hopefully, you get the idea—a great way to quickly find other keywords and then analyze them for profitability and competitiveness.

Feature 4) KDSpy Rank Tracking

The last option lets you track the sales rank of one or multiple books. This way, you can see if these books are selling decently long term. For this, go to the first option, “Keyword Results,” then click on the small “T” to track a specific book.


On the last page, you may see a similar diagram.


Here you can track a book for a few days or more and see its daily sales. As a result, you get a good idea of the consistency of sales for a particular keyword. I suggest you track multiple books for a keyword.
