In advertising and when designing websites, lots of research goes into determining exactly how to place specific items onto the page, photo, advertisement in order to determine the best layout.
Stores do this physically, by putting high-demand items (such as milk or perishables) towards the back of the store. Walt Disney did this when he decided that his new theme park needed a “weenie” in the center of the park to act as a magnet, ultimately drawing visitors towards the Castle that’s become a centerpiece of each of the Disney parks to date.
So while it’s easy to determine traffic patterns when people are walking around, how to businesses determine what makes a good print or online layout?
