Most of us are constantly looking for ways to improve our lives. That’s why self-help books can be so successful. But in order to attract attention, they have to feature a catchy and meaningful self-help book title.

One author of a self-help book tested titles on PickFu, asking, “Which is a more enticing title for a self-help book?”

Option A is Stressless Success. Option B is Stress Free Millionaire.

Can you guess which one won?

Chick lit is the new chick flick. Or maybe it’s better, because for those who crave the lighthearted humor of a romantic comedy, a book lasts longer. But should chick lit book cover art be as frothy as the subject itself? Bestselling author Kate O’Keeffe took her latest novel to PickFu to find out.

She asked a general audience of respondents the following question: “Which cover do you prefer for a fun, feel-good book about finding love?”

Option A shows a bright red cover with illustrations of two characters (sans their faces) and yellow font.

In Option B, the cover takes a totally different turn. With a pink-clad woman and a light-blue background, this cover is as light as a cupcake. It also lacks the blurb by a fellow bestselling author.

Option A reads, “Escape the Hiring Trap: How top companies beat Facebook, Amazon, and Google for talent.”

Option B says, “Win the Talent War: How top companies beat Facebook, Amazon, and Google for talent.”

When you think of retirement, do you feel a sense of happy expectation? Or does the abyss of unemployment freak you out — what in the world will you do with your life?

One author set out to write a book to help us all stress less about retirement called Stop Freaking Out About Retirement: How to Reach New Goals & Enjoy Your Life When Work Ends. She ran a PickFu poll to choose her self-help book cover design.

Option A shows brushes of color behind the title, and a mostly blank, white background. Option B removes the color and adds green falling leaves instead.
