Did you know that more than a quarter of worldwide book sales consist of e-books?

With devices like tablets and Kindle, it’s no wonder, either.

It’s easier than ever to start reading your favourite books on the go.

This also means that there’s more potential profit for you, like an e-book publisher.

I’ve been writing and selling books on Amazon’s KDP platform for a few years now.

I’m no Steven King, but I’ve learned a thing or two that I’d love to share with you.

The biggest thing that changed my book sales was promotion.

Having an ebook promotion strategy is crucial for your success as a self-published author.

You can upload your books and wait, but proper promotional techniques will get you downloads and sales immediately.

Ideas for promoting an e-book

Reddit is your friend

330 million people use Reddit. If you’ve ever been on the website, you know that there’s a subreddit for everything.

And I mean everything.

But, in our case, we’re looking for self-publishing related sections of the website to promote our book.

I’ve gotten upwards of one thousand downloads in a single day from promoting my Kindle books on Reddit. It remains at the core of my Amazon book promotion plan.

But here’s the catch.

You need to have an active free promotion for most of these subreddits to accept your work.

Visit your KDP dashboard and select the promote and advertise button.

Then under “Run a Price Promotion,” click the option for free promotion.

Kindle run a free promotion

You can make your book free for up to five days every 90 days.

I’ve heard many people claim that more than three days won’t produce great results, and I have to agree.

Typically after the third day, downloads drop heavily.

Selecting the date for a free Kindle promotion

In my personal experience, weekends are a great time to promote your book for free, too.

But, test these strategies out for yourself to find the best results. It’s different for every category and audience.

Hit that save button and you’re good to go!

When tomorrow rolls around, and the promotion is active, head on over to the following subreddits:

  • /r/FreeEBOOKS/
  • /r/eFreebies/
  • /r/ebookdeals/
  • /r/wroteabook/
  • /r/bookdownloads/
  • /r/shamelessplug/
  • /r/KindleFreebies/

Sign up for an account if you haven’t already, and submit your book by creating a new post from the right sidebar.

Create a post on Reddit

Every subreddit has its own unique set of rules that you need to follow. These include things like including the genre, author’s name, promotional date, etc.

After you’ve done this, let’s head over to Facebook.

You should look at my freelance writing training to learn more about making money online as a writer.

Don’t underestimate Facebook groups

There are literally billions of active users on Facebook every month.

Active Facebook users

And just like Reddit, there are groups you can find that are specifically about sharing Kindle books.

Just look at some of the groups I’m in myself.

Kindle Facebook groups

Imagine posting to these every time you publish a book. You’d generate so many more downloads and sales.

To join these groups, you’ll obviously need a Facebook account. Go ahead and sign up if you need to.

Then, type Kindle and KDP-related keywords into the top search bar.

Facebook search bar

Select “Groups” from the navigation, and it will display every group related to self-publishing.

Join as many as you want, there’s no limit.

Some will approve you automatically, and others will require verification.

Joining Facebook groups

Post in these groups once you are approved. The key is to stay active and join in on conversations.

Some groups may remove you if you are only spamming your book or promotions. Be a productive member, and you’ll be rewarded.

Do you publish non-fiction? If so, the next strategy is for you.

Linkedin groups are great, too

It should be no surprise that Linkedin is the most used platform for marketers.

Linkedin stats

It’s a hub for professionals, writers, entrepreneurs, and career-oriented individuals.

This also makes it a great channel to promote your book if you write non-fiction like me.

Sign up for a Linkedin account if you haven’t already. Take the time to make an impressive profile.

Include your experience as a writer, a high-quality photo, and a catchy headline.

Then under the “Work” drop-down menu, select “Groups.”

Linkedin groups

It will display groups based on your profile, but you can also use the Linkedin search bar to find specific ones.

Ask to join as many as you like. The more, the merrier!

Like I said with Facebook groups, the idea is to be a productive member of the group to establish a solid reputation.

More users will check out your book and trust you if you do this.

When you would like to share your writing, simply drop a link and ask people to leave feedback.

Posting in a Linkedin group

Now, let’s move on to the last strategy for promoting KDP books.

Submit your book like a madman

You’ve shared your books on Reddit, Facebook, and Linkedin, what’s next?

Book promotion websites.

These are sites that allow you to submit your work to get it in front of a huge email list or social media following.

The best part?

Many of them are free!

Sure, there are paid websites if you don’t mind investing about $50, but a lot of them won’t charge you a penny.

Inkitt is one of them.


Not only will they get your book to thousands of readers, but they will also even offer a publishing deal if it’s liked enough. Not too shabby.

Inkitt is specifically for novels, but there are others that will accept any genre or niche-specific categories.

Research a ton of these websites and store all of their URLs in a spreadsheet.

When you go to promote your latest book, submit it to all of them. You’re bound to get one or two that accepts your submission.

I go over six-figure freelance writing strategies in my high-income copywriting course if you’re interested, as well.

Is Amazon KDP worth it?

I’ve been self-publishing exclusively through Amazon’s program for several years now.

If you’re wondering whether it’s worth it or not to sell your books through them, here’s my answer.

And if Snoop Dogg’s nod doesn’t hint at what I’m saying, then yes — KDP is well worth it.

First of all, it’s free. You can’t beat that.

Signing up is quick, and the platform itself is easy to use.

Amazon guides you step by step through publishing, choosing a royalty rate, and everything in between.

Books are usually approved within a few hours, and they even give you a ton of resources to format them perfectly.

Summing up promoting kindle e-books

Book promotion is easy, and self-publishing is a great way to earn passive income, but you need to market yourself.

Begin by visiting all of the subreddits I mentioned in the first section and submitting your book. There’s probably more popping up, so take a look at the sidebar or search for others.

Join Facebook and Linkedin groups to post your book while it’s on a free promotion, too.

Those three strategies alone would get me up to one thousand downloads per day.

Lastly, narrow down some free promotional websites and offer your book to them. Some require it to be free or a certain price, so do your due diligence.
