Why isn't my book shown on the image you create for my book list?

We do that for three reasons:

1. Based on our testing, it doesn't increase CTR (click-through-rate) to your book list (and it can hurt it as readers need to trust it if they think authors are recommending their own book). 
2. Often, the author's book is a few degrees away from the title of the book list they created. And if we feature your book there, it can lead to confusion.
3. Your book is a smart promotion on your book list, but not included in the list. We want to ensure reader trust, and that difference is key. 

We want to maximize interest in you, your book, and your list.

Based on our testing, we have found that featuring just the 5 books that are recommended is more effective at driving traffic to your book list. The more traffic we get to your book list, the more people meet you and your book (and click to buy it). 

Our #1 goal with that image is to pull readers to your list, as that list is incredibly effective at showing them your voice/passion and leading them to check out you and your book. 

The author's book is often a few degrees away from the title of the book list they created.

Often, the list's title isn't a perfect match for the author's book. As it can be a few degrees off or even parallel to the author's book. So we didn't want the image to confuse readers and instead focus on the five books you recommend. 

For example: If an author creates a book list about "the best non-fiction books on mummies," and their book is a historical fiction book set in ancient Egypt, it can really confuse readers and reduce interest/clicks.
