Book promotion comes in all shapes and sizes. Here are a few things to keep in mind.
Book Visuals and Pricing
It starts with your book cover. The Book Designer talks about recent cover trends that may give you some ideas (what colors to use, how to use typography, types of images, and more).
For print books especially, you’ll also want to work on the spine and the back cover.
Another thing to consider is the price of your book. Again The Book Designer has some advice, which includes analyzing prices on Amazon with the KDP Pricing Support service, taking into account length and genre, and changing your prices.
