Don’t ever underestimate the importance of a quality cover. But it goes beyond that. When designing your book cover, look at best sellers in your genre for ideas. General layout, font styles, and even the predominant colors should be similar. You want to fit in with the best.
If it doesn’t fit in with what readers are looking for, they’re likely to ignore it. Make sure it’s an accurate representation of your story, its genre, and good design. You want it to be worthy of all the hard work you put into writing it, not look like it was thrown together just to get the book published.
It’s acceptable to change your cover after your book is published, if you realize you goofed after the fact. Sometimes this can give it new life all around and attract readers who missed it the first time.
