Kindle Direct Publishing (KDP) has several optional components you should know a little about before deciding yeah or nay. One of these is enrollment in Kindle Select.

Kindle Select is only for your digital books, not your print books. If you enroll, you earn a percentage of the KDP Select Global Fund for pages that are read either through Kindle Unlimited (KU) or Kindle Owners’ Lending Library (KOLL). Enrollment gets your book in the KU or KOLL library so that readers can choose to read it with their paid subscription. If you don’t enroll, your book isn’t in the list and readers who use KU or KOLL won’t have access to it.
You also can earn the maximum 70% royalty rate for sales in Japan, India, Brazil and Mexico rather than the customary 35% rate. Since my books are about Mexico, geared to those living in Mexico, this is an attractive option.

Through Kindle Select you can also use some nifty promotional tools. The Kindle Countdown Deal will discount your book for a period of time. This discount is only available to books for sale on the UK or US Amazon site. You still earn your 70% royalty rating on the discounted price. There’s a dedicated page on Amazon called Kindle Countdown Deals which the savvy book reader will have bookmarked, leading to more sales of your book.

The way the countdown deal works is you can reduce your book price, then each day the price gets just a little higher, until it returns to the regular list price again on the fourth day. So if you discount your book to 99 cents the first day, the second day it will be $1.99. The third day it will be $2.99 before returning to the list price of $6.99.

The Free Book Promotion will allow you to offer your book FREE (hence the name) worldwide for 5 days each 90-day enrollment period. You can run the promotion 5 days in a row or you can pick individual days during the 3-month period. While this is a great publicity tool, you won’t earn any royalties on any free downloads. If your book gets a large number of downloads, it just might be listed on the Amazon Best Sellers Top 100 Free list.
Both promotions will certainly help get your book in the public eye. You can’t run both promotions at the same time though.
Here’s the fine print. If you enroll your digital book in Kindle Select you can not make your book available on any other platform, including your blog, website, or other publishing sites. You can make up to 10% of an enrolled book available as a “sample” on your blog or provide reviewers and editors a digital copy.

Your enrollment in Kindle Select will automatically renew after 90 days. Therefore, if you do not wish to continue with the service, you need to uncheck the automatic renewal box on your bookshelf on KDP. You can re-enroll at any time.
Very well explained. Thanks for writing this great article about KDP. It’s a hard choice, to be on only one site or not, especially when it means potentially making more royalties.

It is a hard choice. It seems like it would be better to diversify with different publishing sites but with the perks of using KDP, at least while you become better known, it just might be in your best interest to try it out.
