Marketing ROI. For most marketers — this is the holy grail — knowing exactly where to spend our next dollar to get the largest impact and return. I can’t tell you how many times I’ve heard from our investors and board that all they really want for marketing to answer is: How are we performing? How much is it costing us? Are we getting better? And despite the prevalence of new account-based platforms and significant investment in data and technology, according to a recent Nielsen study, only 1 in 4 marketers are highly confident they can quantify ROI.
