Your product catalog page is frustrating users, and you don't even know it. Chances are you're using cards to display your products, but the cards all look the same. Having only one card type isn't good because it creates a limited, one-dimensional browsing experience.
A one-dimensional catalog page causes users to sift through each card individually to find what they want. Since the images and text are the only perceivable differences, they have to scan each card more closely.
Adding more depth to your cards enhances the user's perception of your content. They'll be able to recognize product qualities by card size and shape. Above all, your catalog page will look more interesting to browse.
