Most self-published authors already understand the importance of great cover design. When it comes to marketing their book, the cover design is their primary sales tool, the face of their project, and the thing that can elevate them to a professional standard in the eyes of readers. But, if authors know this, why do so many still create their own book covers?

Most often, it comes down to resources. Professionally designed book covers cost money (but not as much as you might think), and often, authors end up asking themselves: does a professional book cover actually get you more clicks and sales?

The Professional Cover Test

To answer this question once and for all, we recently ran an experiment, in which self-published authors were invited to get their book covers re-designed by an experienced professional on Reedsy.

Four titles from a range of genres were selected and entered into an A/B test: over the period of a week, we ran two Facebook ads for each book. Both ads were identical in every way — except for the cover image — and exposed to approximately 1,000 users from the same audience set. That way, we would discover how much the re-designed cover impacts the click-rate rate of an advert.

On average, we saw a 35% increase in the marketability of books with professional covers.

What does this mean? For each test, the professionally designed cover had a click-through rate that was 12.5–50% higher than their non-professional counterparts. Let’s take a quick look at each of the redesigns and let our designers explain their approaches.

Once a Bridesmaid — 48% more clicks

Author: Courtney Hunt

Genre: Romance

New cover created by... Caroline Teagle, an in-house designer at Penguin Random House.

Facebook Ads Targeted to: Women; aged 25-64; who like Cecelia Ahern, Jude Deveraux, or Julie Garwood

Synopsis

Always a bridesmaid… and that’s exactly how professional bridesmaid Lauren Bennett wants it. When a case of mistaken identity lands her in the bed of photographer Kyle, she finds herself entering into a battle of wills with a born-again romantic.

The Redesign

“I tried to select images that gave a sense of character and went in a bit of a softer, women's fiction direction,” Caroline Teagle told the author. “I wanted something clean and fresh for the color palette and typography.”

While staying with the original cover’s concept — bridesmaids holding bouquets — Caroline chose an image with an improved white balance, creating a greater contrast of colors. She then turned her attention to the typography.

“I feel like scripty wedding-invitation type font is fairly cliché, and when the bridesmaid is in the title and the image immediately signals wedding, it's not entirely necessary.”

In her final design, Caroline employs a simple sans serif font for the title and author name, and made sure the logline wasn’t lost — improving readability when reduced to a thumbnail.

Learning Points Use genre trends to your advantage while still avoiding cliches.

Brighter, higher contrast images can help your cover pop in thumbnail form, as will simpler fonts.

Author: Richard Risemberg

Genre: Mystery & Thriller

New cover created by… Mark Thomas, a talented multi-disciplinary designer based in Wales, UK.

Facebook Ads Targeted to: All genders, aged 25-60, who like Walter Mosley, James Ellroy, Raymond Chandler, or Michael Connelly

Synopsis

1978: The wave of gentrification has yet to break over downtown Los Angeles. When his friend nags him into tracking down a missing girlfriend, straight arrow Lennie Strasser reluctantly agrees. His quest takes him into the hobo jungles and punk squats by the LA River — and into a world of moral ambiguity that changes Lenny's life in ways he'd never dreamed of.

The Redesign

Upon reviewing Richard’s existing cover, Reedsy designer Mark Thomas first addressed its biggest problem: “The immediate issue that seemed to be holding it back was literally one of visibility: the cover was just too dark!”

“I got on the phone with the author to discuss the book and get a feel for the story and the tone that he wanted the cover to set. It turns out that Richard is a quite gifted photojournalist, which gave me access to a number of his photographs of LA.”

Whilst not totally contemporary to the book’s setting, Mark ended up using one of the author’s photographs as he felt it provided a flavor of Los Angeles’ seedier industrial side. Retaining the author’s monochrome concept, Mark substantially brightened the cover, while keeping the gritty, downtrodden feel.

“Another fairly important change was to make Richard’s name more of an impactful part of the front by greatly increasing its size and prominence,” Mark told us. “The final cover ticks a number of boxes: a bolder author branding, a selective cropped use of a photograph of a female vagrant and typewritten representation of the book’s title.”

Learning Points Make sure your cover is bright enough. If you’re struggling to read the title, that’s a red flag.

Consider presenting the author’s name as a brand.

A cover doesn’t need to be loaded with color to be ‘cool.’

What Would a Muslim Say? — 12.5% more clicks

Genre: Non-fiction

Author: Ahmed Lefty Rashed

New cover created by… Stewart Williams, a prolific and eclectic designer of covers ranging from cookbooks and novels, to a collection of screenplays by filth maestro John Waters.

Facebook Ads Targeted to: All genders, aged 25 - 60, who like Theology, Religious Criticism, or Christianity

Synopsis

“There are many books that teach Islam, preach it, criticize it, or academically explain it. This book is different. This book is a compilation of actual conversation transcripts, showcasing everyday people asking real questions and getting straight answers about Islam.”

Redesign

Communicating via Reedsy’s messaging platform, cover designer Stewart Williams was able to discover the author’s purpose for this book: to speak to non-Muslim Americans and dispel misconceptions about the Islamic faith. With that target audience in mind, Stewart presented a number of concepts in line with contemporary non-fiction titles.

“I wanted the book to be inviting to those who might otherwise be put off by topics about Islam,” said Williams. “This wasn’t going to be easy, given the contemporary political tone. When dealing with political or potentially hot issues, I try to make sure I understand the topic, or at least research it before developing imagery.”

“Above all, this cover had to be a mix of things: gentle and inviting, scholarly but approachable.”

Working with colors and symbols associated with Islam, Stewart landed on a final design that let the book’s title speak for itself. In the Facebook ad test, it was essential for the audience to be able to read that subtitle.

Learning Points Research and understand not only the book’s content, but the types of books your target audiences are drawn to.

If you want the audience to read what’s on your cover, make sure it’s large enough.

Author: Katherine Heason

Genre: Young Adult, Fantasy

New cover created by… Chuck Regan, an illustrator and designer with an extensive background in advertising.

Facebook Ads Targeted to: Women, Aged 16-35, who like Kami Garcia, Suzanne Collins, Veronica Roth, or Cassandra Clare

Synopsis

Seventeen-year-old Lillith is just an ordinary girl, living in a quiet seaside town. All she has to worry about is her impending exams and her non-existent love life. When her past catches up with her present, she's flung into a world of witchcraft that sees her desperately fighting for her life and her new-found soulmate.

The Redesign

Before work started on the new cover, author Katherine Heason sent Reedsy a short description of her main character. “Her name is Lillith, which means ‘dark angel’ — she certainly has darkness in her. Her eyes are bright green, luminous even, which ties into her powers. She lives on the English coast, where it’s cold and there’s lots of wind.”

“I immediately pictured a Celtic-looking teen,” commented designer Chuck Regan. “A bold and intimate close-up of a girl with energy swirling around her. I narrowed my stock photo search to reasonable matches, and found a photo that the author said was perfect. Boom! Magic.”

Manipulating the stock image of the girl, Chuck was able to add loose strands of hair to suggest the character’s wind-swept look and magical aura.

“Katherine helped clarify the best way to illustrate the type of magic portrayed in the story — subtle and intense, with an implication of hidden dangers. The flames in the title text were also her suggestion, adding another layer of energy to the cover.”

In general, Chuck’s redesign is far less cryptic than the original, in that it tells us quite a bit about the book. From the cover alone, a reader can discern that its main character is a young woman, that magic might be involved, and that it probably belongs to the Young Adult genre: all things that readers will want to know.

Learning Point Covers should communicate something about the book, whether that’s character, tone, or genre.

Why do professional covers matter?

An effective cover will get relevant readers responding to your ads and heading to your Amazon page. Once there, the design will communicate the tone and content of your book and get more (of the right) readers to buy or download it. This, in turn, improves your chances of positive reviews and ratings, which will send you up Amazon’s rankings, giving your book greater visibility, leading to even more downloads. More so than in most markets, self-publishing benefits heavily from the snowball effect.

And we haven’t even touched on how your cover can be used for reader magnets and crowdfunding campaigns!
