“Sex sells” might be cliche, but the reason the phrase has stuck around this long is that it’s true. And it’s a good thing to keep in mind when selecting e-commerce product images.

In a recent PickFu poll, an online seller ran a split test asking respondents to choose between two featured images for an exercise belt.

Option A depicts a model wearing the belt with an inset showing the back view of the product. Option B shows a model wearing the belt, but with a different pose. An inset advertises that a wrist wrap is included. In Option A, the brand name on the belt is “posture.” In Option B, it is “GO4FIT.”

Since the contents of a subscription box are ever-changing, the box itself must represent the brand and convey what treasures customers can expect when they open it.

The Tapas Club, a gourmet Spanish food subscription box, recently used PickFu to get feedback about the design of its box. The seller received 50 responses from the general population in 24 minutes.

Option A features red and white Spanish tile print, while Option B’s multicolor illustrations showcase different aspects of Spanish culture.

When designing the main image for a product that consists of multiple pieces, it’s critical to think about how the component parts are arranged.

In a recent PickFu poll, one Amazon seller split tested two main product images for a Treasure Box toy set. The seller received responses from 50 members of the general population in 26 minutes.

In Option A, the toys form a clump in front of the box, playing off the visual we associate with a treasure chest: a pile of gold, silver, and jewels straight out of a tale of swashbuckling pirates on the high seas.

Option B shows the toys neatly organized in front of the box, with like items displayed together.
