What compels someone to pick a book off a shelf that’s chock full of choices? Or to click on a book in a seemingly infinite online store? 

It’s the book cover, of course. The cover that’s the most eye-catching will get the most interest. So today, we’ll discuss how testing will help your book cover stand out from the pack.

Let yourself be wrong

When a colleague suggested he re-design his book cover, author Temple Emmet Williams reacted as many of us might: “What the hell’s wrong with my cover?” he asked.

There was nothing wrong with his cover, and he intended to prove it. He designed some new covers and then, to make his point, took his least favorite design and tested it against the original cover.

His least favorite cover was overwhelmingly favored in the poll. It wasn’t even close: 85% chose the alternate cover over the existing one. 

But Temple was still skeptical. He had two cover designs left. One featured a man facing the sunset. The other showed medical staff, including a woman whose eyes were so piercing that her cover was Temple’s preference.

The author loved the doctors. Readers were creeped out.

Much to his shock, the photo of the medical staff was off-putting, and those piercing eyes didn’t help. While the results were closer, two-thirds of respondents still preferred the sunset.

Some typical responses in favor of the sunset made Temple aware of something he hadn’t even considered: doctors can seem scary, especially behind masks. Here’s a sampling of the comments:

  • “If you have been through a serious illness like I have, doctors with masks on is the LAST thing you would want to see every time you would pick up this book.”
  • “doctors creep me out — i can relate better to the other picture”
  • “[Option B] is pleasant and not as scary and intimidating like the other one. It looks more like a story of hope.”

With two clear winners from his two polls, Temple tested them against each other, with double the sample size. He was sure this final matchup would be close. It wasn’t.

63% of respondents preferred the purple version over the yellow. They found it warmer and more inviting, and remarked on its readability. They also associated the color scheme with hope, vibrancy, and inspiration. Temple said, “All of the information people volunteer when they make their choices, the words they use and emotions they reveal, become a goldmine for improvement.”

Feeling confident in the appeal of the purple cover, Temple re-released his book. “I believe that change has a direct connect to the book receiving a B.R.A.G Medallion, and also a Gold Medal in the Reader’s Favorite Book Awards,” he said. 

Takeaways from Temple’s story

  • Be open to feedback. Like Temple, you may not be aware that the imagery or color scheme you’re using might be unappealing. 
  • Start general, then get specific. Temple began his tests with very different designs. Once he understood that the sunset imagery was the best direction to head in, he tested different color palettes on that same design. 
  • Don’t just look at the vote tally. Sure, having a runaway winner in each poll can be great, but be sure to read the comments closely to understand why an option won over the other. Look for themes and recurrent reactions in the feedback. Use these insights to revise your cover design.

Avoid this pitfall

Your book title is distinct from your cover design, and creating the two should be separate processes. Each has different considerations and will be judged using distinct criteria. Testing more than one thing at a time is problematic because it skews your results.

When you’re testing book covers, make sure that each design option includes the same information. If you tested two cover designs and each cover had a different title, for example, you wouldn’t know whether respondents preferred the design layout or the title on that design layout.

Below is an example of an author who tested two covers. However, the two titles are different, only one option included a subtitle, and only one option included the “superfitdads” logo. Any of these variances may have skewed the results.

This poll would be less biased if each cover included the same title, subtitle, and author attribution. Then, the only test parameter would have been the cover design.

Here’s a better example. This author is testing two cover designs. The title, subtitle, author attribution, and even graphic layout is the same. The only difference is the “Action Plan” stamp. By only testing one thing at one time, this author knows the stamp helps his cover.
