Attribution In Performance Marketing: You Can’t Drive To Hawaii

I am on my way to Hawaii to meet my family for a vacation and looking forward to the beach, sun, and surf but what a journey it will be with 3 kids all under 6 years old, including a one year old. When I arrive at the hotel in Maui I am sure I will be greeted at the front desk with a fresh Hawaiian lei and a warm smile followed by, “Aloha, where did you folks come from?”  That answer really depends on whom you ask.
