There is a big difference between marketing for a brand and now always knowing your exact quantitative output in monetary value and performance based marketing.

There is a big difference between marketing for a brand and now always knowing your exact quantitative output in monetary value and performance based marketing. I work in performance based marketing running a variety of online ad campaigns for a number of clients. At the end of the day you always know exactly how much revenue you brought in and at what margins. It's exciting, creative, and extremely data driven. In this day and age marketing is partly creative, but is also subject to a variety of algorithms and mental calculations.
