Why it matters

Your Cover Is Your Most Important Marketing Asset

Readers judge books by their covers. Always have. Always will. Studies consistently show that cover design is the single biggest factor of online book purchase decisions. At least 70% of book discovery now happens on mobile devices, where your cover is displayed at the scale of a postage stamp. Get your free guide and learn how your book can stand out.

The four main book cover objectives

Stop the scroll

Catch a reader's eye in seconds.

Signal your genre

Readers approach covers with expectations.

Communicate quality

Professional design communicates a professionally written book.

Work at thumbnail size

Great covers get seen - small

The thumbnail test: before finalizing your cover, shrink it to the size of your thumbnail on a phone screen. If your title isn't readable and the image doesn't pop at that size, your cover needs a redesign.
