McLellan Marketing Group view marketing through the same lens. None of their clients, no matter how large, has an infinite budget. Every dollar they spend has to yield something that gets them closer to the finish line. Sometimes the yield is that they learn something new about their prospects. Sometimes it’s that they get a repeat sale from a happy client. And often, it’s that they have moved a prospect a little further in the sales funnel towards their first purchase. Marketing is an imprecise science for sure. But that doesn’t mean they can’t measure. They start every new client relationship and project by defining what they are going to measure. They set success metrics and then gauge their efforts against those tangible measurables.
