I have always wondered about the success of calls-to-action on billboards. These are things like phone numbers or long web addresses. The headlines and big pictures barely make an impact at 70 miles an hour. What are we supposed to do with a request to text our pizza order when it appears on a billboard? It’s hard enough to capture the phone number from the billboard, but it is also illegal in many places to text and drive. And where do we have the pizza delivered?
