Book Sales Analysis 2025: Best Month of the Year for Amazon Free Book Offers

I’m Jon Lymon, an indie book author whose best selling titles include the novel The Wronged and the novella The Ghost of Christmas Threeve. Not heard of either? Well, like I said, I’m an indie book author.

For the whole of 2025 I tracked the sales, giveaways, and KENP performance of my books (10 novels, 3 novellas and several children’s books). The tracking was carried out manually, looking at reports from Amazon and D2D. No Ai was used, because Ai never needs to be used when you have a brain.

Now I’m sharing some of the results, which may or may not be of interest/assistance to other indie writers. If not of interest, best move on.

About Amazon Free Book Offers

To offer a customer a freebie of your book on Amazon, you need to register with KDP Select, which means the digital edition of your book can only be available for sale on Kindle/Amazon. So you’ll need to delist it from other platforms. And I recommend you do follow the rules as you don’t want an email from Amazon. They will find out.

KDP Select enrolment lasts about 3 months. This allows you to offer EITHER a Kindle Countdown Deal or 5 days of free giveaways during the 3 month term. I’ve had plenty of success with the latter, but Countdown deals haven’t worked with me.

Which month of the year was best for free book giveaways?

3^rd best month of the year for free book giveaways: JANUARY

2^nd best month of the year for free book giveaways: DECEMBER

Best month of the year for free book giveaways: MARCH

Learnings:

My biggest free book giveaway was on Boxing Day, so it’s no surprise that December figures highly on these results.

But it was beaten into second by March. This was the month of World Book Day and National Read to Me Day. So books are often higher profile on these days, helping to raise the number of giveaways.

Thursday 5 March is World Book Day in the UK in 2026, (it’s always the first Thursday in March) so it could be worth focusing a freebie giveaway on or around this date to see if you can generate interest in your titles.

March 19 is International Read to Me Day.
