The featured book is editorial, meaning that one of us goes in and features those books, bundles, and courses that we think will either get the most sales, display an especially good example of a high-quality Leanpub book, promote an interesting sale, add to some buzz an author is experiencing, etc. We typically change the featured book, bundle, and course, every weekday.
If you want your book considered for being featured, please make sure to do the following:
Set up your author profile, providing a nice profile image, and a robust description of yourself. A good profile makes a huge difference in establishing confidence in potential readers of your book. You can do this (and even add a video from YouTube to your Leanpub author profile page) here:
Also, make sure to add robust information about your book, which you can do here:
leanpub.com/YOUR_BOOK/settings/about
...making sure to replace YOUR_BOOK with your book's unique "slug".
Once you have set up your author profile information and your book's information, please email the URL of your book to hello@leanpub.com with your request to have it featured, and we'll consider it :)
