Lately, self-help books with swear words have become their own genre. Some people love a good expletive. Others find them vulgar and unfit for genteel society.

But let’s admit it: we’ve probably all cursed before. Do we want to see swear words in book titles, though?

One PickFu user tested this very question for a book about losing weight without a diet.

Option A reads, “Fuck Diets. Discover the 4 Ridiculously Simple Habits to Effectively Stop Your Body From Storing Fat and Look Fabulous.”

Option B says, “You Look Fabulous! Discover The New 4-Habit Secret To Painlessly Get The Body Of Your Dreams Even When You’re Over Diets.”

Can you guess which one won?

Some authors have a love-hate relationship with book descriptions — especially those that appear on jacket covers. On the one hand, what if they give too much away? But on the other, what if they don’t provide enough information to tantalize readers? How does an author find the perfect balance?

One PickFu user made this burden easier on herself by testing her two book descriptions in a recent PickFu poll. Since the book is aimed for a female audience, she asked an audience of 50 women, “Which book description is more appealing?”

Even if you’re not much of a dog person, you pretty much can’t resist smiling when you see a puppy. Just try to glare at one. I dare you.

(It’s impossible.)

But if you are a dog person and you’ve just brought home a cuddly new ball of fur, exactly what version of puppy sweetness do you love the most?

One author recently took to PickFu to ask 50 Amazon Prime members their opinion of three dog book covers about keeping puppies happy and healthy in their first year of life.

There’s nothing like walking through the Romance section of your local bookstore. Bared abs and breathy-looking women abound. If you’re brave enough to pluck a book from the shelf, you spend the entire time at the cashier’s desk hoping no one judges your reading choices.

But what if nudity isn’t the only thing that can sell a romance novel? One publisher tested this question in a recent PickFu poll. She posted two romance book cover ideas and asked an all-female audience, “Which book cover do you like better?”

Option A shows a fully dressed man in a suit. A stubbled chin turns to the side; the top buttons of his shirt are open.

In Option B, we get standard Romance-cover fare: a full set of ripply abs and pecs.

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.

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.
