How to Increase Your Amazon Kindle Book Sales by 600% in a Week

By Sean Ogle •  Updated: 10/29/21 •  9 min read

This is a guest post from Tristan King, an entrepreneur and writer who recently published his first book on learning langauges on the Amazon Kindle store. 

Recently, I experimented with Amazon’s KDP Select Program, a new system on the Kindle Store which increased my book’s sales over 600% within one week. First I’ll tell you the story, then I’ll share how you can do it too.

Amazon KDP: Hitting the Publish Button Increase Kindle Book Sales

“What have I done? What if no one likes my book?” I thought, finger poised on the yellow ‘Publish’ button.

After 9 months of writing, the moment had finally arrived to send my book out to the world. Remembering the encouragement of several ‘real’ authors much braver than I am, I hit the button.

Soon after, an email arrived saying that I was now live on the Kindle Store. No going back now!

Over the next few days, sales trickled in slowly, and I even had one positive review. This was extremely exciting. I wondered what the next step was: How can I get the book into more people’s hands?

I’d read about a program called KDP Select, Amazon’s lending program, at which they’re throwing lots of money and promotion.

What is Amazon KDP Select?

Here’s the rundown on KDP:

The catch: it must be exclusively sold on Amazon. No Apple, no B&N, no PDF website sales. Exclusivity? Sounds like a tough decision, right? It wasn’t for me.

Up until that point, through the Apple iBooks store, Barnes & Noble, and Sony’s Nook eBook store, I had sold a grand total of zero copies.

Every single sale I’d made was on Amazon.

Given I wasn’t making any sales on the other platforms anyway, why not try it? I unsubscribed my book from Smashwords faster than you could say “why haven’t I sold any copies through you?“, and enrolled in KDP Select, making my book free for a 24-hour period.

Then, things got interesting.

The KDP Select Experiment: Results

After the first hour of “free” promotion, I checked how many copies had been downloaded.

50 copies in an hour!

I almost fell off my chair. Yes, they were free downloads (i.e. I didn’t make any money off them), but I was ecstatic because it meant:

  1. My book now had the chance of helping 50 new people learn a foreign language (this is the whole point!)
  2. At least a few people were interested in what I had to say.

2 hours down, 80 downloads. While I slept at night, it was downloaded over 200 times.

At the end of the 24 hour period, my book had been downloaded 400+ times – a lot more than I’d sold during six weeks of being in the Kindle store.

After the freebie period was over, people continued downloading the book. Not at the same rate of 20-50 sales per hour, but in the following week I had a 600% increase in sales.

To be clear, we’re not talking Stieg Larsson numbers here, but for me as a first time author and newbie to Amazon, this was a breakthrough, and made me grin like a little kid.

Here’s what my sales figures have looked like:

  • December 28th – Feb 15th:  25 sales (six weeks)
  • Feb 15th – Feb 28th, straight after KDP Select promotion day: 30 sales (one week).  Sales have continued to trickle in since then at a much faster pace than before.
  • Total downloads in the month of Feb: 513 (some free, some paid)

Why My Kindle Book Sales Increased By 600%

In my experience, four things contributed to the increase in sales:

1. People like freebies, and they like “expensive” freebies

If you won a car in a competition and had two choices – a $20,000 car for free, or a $2,000 car for free, which would you pick?


Prior to this promotional period, my book was $7.99. When it went “free” on the Kindle store, it said $7.99 FREE. This meant an $8 ‘discount’ during the free period, as opposed to books which were normally 99 cents, and are then free during promotion ($.99 discount).

This, of course, doesn’t mean my book is better than anyone else’s which is lower priced: but it gives the impression of a larger discount. I suspect this increased the number of downloads.

2. Getting in the top twenty lists, and staying there after the promotional period

When someone downloads your book (for free or paid), it moves up the charts. My book was #1 in the “Bilingual” section for a while, even though most people downloaded it for free. This meant a lot more people saw it, compared to when it was down in the dungeons of Amazon’s search listings. Amazon does not kick you off the charts after your free promotion ends.

Being in the charts when it reverted back to a paid download meant more people saw it, and resulted in more sales.

[Please note:  Since this original post was written, Amazon has changed their ranking system.  Your book will no longer stay in the normal ‘best sellers’ based on free sales.  Only paid sales now count towards permanent rankings.  Also, sometimes the price is no longer displayed next to the word “Free” for some books.  Whilst much of this article is still relevant, we’d also suggest consulting other reviews of the KDP program to make sure you have a balanced view.]

3. Increased cross-promotion

When people download your book, it starts appearing in the “People who bought this book also bought..” and “Recommended for you” sections, further increasing visibility.

This is similar to eBay’s “We recommend..” or YouTube’s “Recommended videos” cross-promotion: addictive, aren’t they?

4. Reviews bring more authenticity to your book

More downloads = more people reading = more reviews. I still don’t have a ton of them, but a few stars next to your book makes a difference for fence-sitters.

How to Increase Your Kindle sales 600%

Below are some basic guidelines on how to get a book into the Kindle Store, as well as how to approach the KDP Select program to boost your sales.

Step #1: Write your book

You can do this in Microsoft Word, Google Docs, Scrivener or any number of other writing tools.

Step #2: Format it using Amazon’s quite strict but very logical Formatting Guide

I’d suggest reading this guide first in order to set up your MS Word file for minimum re-work.

After my book was finished, it took me around 6 hours to format it to their guidelines. This can easily be outsourced for under $100 on Upwork, too.

Minimalist formatting is necessary because users can increase or decrease the text size on their Kindle / iPad, so font size, page numbers and coloured headings become irrelevant.

You can find all of Amazon’s formatting guidelines here.

This Kindle Publishing guide may also prove useful.

Step #3: Create a cover, or get one designed

Fiverr or 99 Designs are good for this, or you can do it yourself if you’re game. I purchased a photo from for $80, which gives me license for up to 499,999 book sales.

If we ever go over that, then that is one license I’ll be more than happy to revisit then!

Details of Amazon’s Image Guidelines are here.

Step #4: Convert your MS Word Document to Amazon’s format

First, “Save as” Filtered HTML, and then into Amazon’s format (PRC) using Mobi Pocket Creator. This sounds complicated but takes less than 5 minutes.

The Guide to Conversion and Formats is here.

Step #5: Create an Amazon KDP account, upload your book and set the price

Your book will be available on Amazon in the US, UK, Spain, France, Italy and Germany. You can opt out of some if you want.

For prices $2.99 – $9.99, Amazon gives you 70% and takes 30%. For anything outside of that, Amazon takes 65%, and you get 35%.

Step #6: Create an author page on Amazon Author Central

Write a bio and add a photo – you are now an author!

Amazon’s Author Central page can be viewed here.

Step #7: Enroll in the KDP Select program

Enroll in the KDP Select program making sure your book is available exclusively to Amazon (or they won’t pay your royalties!). Enrollment is by clicking one button. Make sure to set a promotion day to see the effect of free downloads on your paid sales.

If your book is borrowed by KDP members, you’ll also receive a share of the borrowed royalty pie. (For me, this is so minute as to not be relevant – yet.)

Step #8: Experiment with different promotions

I tried my first free promotional period on a weekday.

The second time, I tried it on a weekend, where I figured more people would be lazing about on the couch browsing the Kindle Store.

The second time around, free downloads were lower overall, but I did see another big increase in downloads after the promotional period ended. I’m still experimenting with this.

The Amazon Kindle Publishing Wrap Up

Will this work for everyone? I’m not sure yet. Your mileage may vary, and everyone’s book will be different. I do believe that KDP Select is, if nothing else, a fantastic way to experiment with price points, get your book out into the world, and have some fun.

Hopefully, your message will get into more people’s hands than it would have otherwise: that’s the whole point, right?

That’s all, folks! It’s not difficult to publish an information product onto the Kindle Store. Authors and information agents – go make it happen!
