I think cover images sell more books. No stats of my own to back that up, but Crime Bake’s done their homework and provided some impressive statistics on what a publisher’s listing your novel’s cover image does for sales.
Crime Bake is offering a course in marketing, an area I know so little about but hope to learn a great deal as I progress and build my author’s platform.
Just passing on to RGBers what I learn about covers and cover art. Here’s the link to their post.
