I found this exercise very helpful. Wireframing (what I call reverse engineering wireframing) helps crystalize existing design ideas, simplify it to help the student understand what elements of design are present. Doing this exercise helped me realize that a seemingly simple page contains a lot of well-thought-out components. See full conclusion below after 3 screenshots.
I would argue that the seemingly simple shopify pricing and plan page is very well designed: encompasses many variations of call-to-action, presents relevant information keywords and FAQ, highlights desired outcomes. That’s a lot of information on a small seemingly bare page, with all the right elements but more robust information.
