In the current marketplace (no matter the channel), consumers want as much information about a product before purchasing and delivered in an easy-to-digest format. It's very important to deliver complex information or highlight the top benefits/features in a quick, visually appealing way. There are several elements to designing the perfect infographic- visual, structured layout, concise text and color themes.
Questions you could ask:
"Click on what features stand out to you first, second and third"
"Which collage do you prefer and why? Is one more visually appealing or informative than the other?"
"How clear is the information listed in the infographic? Is there anything else you wish was highlighted?"
"What color themes do you think best match this product? What feelings come to mind when you look at your favorite?"
