The self-publishing revolution has brought forth a generation of cover art critics. It seems that there are many more cover art critics than there are art critics.

To be fair, they also criticize traditionally published covers, and a few of the best covers out there are actually on self-published books. However, the reality is that the vast majority of lousy covers are on self-published books.

Anyone can be a cover art critic. No talent for cover design is needed to form an opinion.

But that’s the point. Don’t create a cover to satisfy the critics. Instead, create a cover that will please potential readers. Back to the point: All potential readers are cover art critics! Complaints that are common among the cover art critics tend to deter sales because many readers feel the same way.

Here are some common complaints:

(1) Can’t tell what the book is about!

(2) Text is illegible!

(3) Colors don’t work well together!

(4) People look deformed!

(5) Used crayons or colored pencils!

(6) Photo-bombing image!

(7) Used Comic Sans for font!

(8) Aspect ratio is distorted!

(9) Illustrator’s name appears on a lousy cover!

(10) Image appears blurry or pixelated!

(11) Cover is too busy!

(12) Fonts are boring!

(13) Hard to read fonts!

(14) Wrong words emphasized in title!

(15) Three different fonts used!

(16) Images have nothing in common!

(17) Settled for image that doesn’t quite work!

(18) Doesn’t look good both full-size and as thumbnail!

(19) Red-eye!

(20) Typo in title!

(21) Poor drawing skills!

(22) Poor photography skills!

People do judge books by their covers. As they should! At least to the extent that buying a book where the author or publisher didn’t put much effort into the cover is a risk: If little effort was put into the cover, there isn’t any reason to expect that greater effort was put into writing, editing, and formatting.

The cover is a marketing tool. Customers do browse for books in search results and click on thumbnails that interest them. Trying to avoid common cover design mistakes may pay off. It’s challenging to design a perfect cover, and any cover – no matter how good – can still be criticized. It’s much easier to find fault in a cover than to make a cover without fault. (No wonder there are more cover art critics than there are great covers.) But the cover is very important, so striving to design a great cover is worth the effort.
