Amazon Best Sellers lists are divided into Top 100 Paid and Top 100 Free in the Kindle Store. While your book is offered for free, it will have a sales rank in the Free list. Once your Free Book Promotion is complete, your book will enter the paid Paid list.

It can take several hours for books to transition between the Free and Paid lists before and after promotional periods. In some cases, the transition may take longer due to system latencies. Since the start and end times of promotions are based on midnight Pacific time, the exact time your book reflects a free or paid sales rank will vary depending on the time zone from which customers are viewing your book. For example, customers in time zones other than Pacific time may not see books reflected in the free list until much later in the day, depending on local time.

The Amazon Best Sellers calculation is based on Amazon.com sales and is updated hourly to reflect recent and historical sales of every item sold on Amazon.com.

Your book will drop in sales rank in the Paid list from the time your free promotion begins to the time it ends. However, since sales rank takes previous sales into account as well as recent sales, your previous paid rank will influence your new rank when your book enters the paid categories again.

To schedule a Free Book Promotion after your book is enrolled in KDP Select and available for sale on our website:

1. In your Bookshelf, click Promote and Advertise next to any book enrolled in KDP Select.
2. Select KDP Select Info.
3. Under "Run a Price Promotion," select Free Book Promotion ("Kindle Countdown Deal" will be selected by default*).
4. Click Create a new Free Book Promotion Deal for this book.
5. Enter the desired start and end date and click Save. Avoid ending your promotion on the final day of your KDP Select term.

*You can schedule your Free Book Promotion wherever your KDP Select enrolled title is available for sale. Kindle Countdown Deals are only for titles available on Amazon.com and Amazon.co.uk.

Promote and Advertise lets you schedule one or more free promotions, edit or delete a scheduled free promotion, or stop an ongoing free promotion. If you choose to stop an ongoing promotion, it can take from a few minutes to several hours for the action to take effect.

To provide the best reader experience, note that on the days your book is offered for free, it will not be included in the Kindle Owners' Lending Library.

We're currently unable to schedule a Free Book Promotion ahead of time for a future enrollment period or to roll over unused free promotion days from one enrollment period to another.
