When the world?s biggest brands want to sharpen their digital marketing strategy, they call Neil Hoyne ? Google?s Chief Measurement Strategist and Senior Fellow at the Wharton School. In his first book, he offers a simple, research-backed playbook that anyone can use to find their best customers and develop relationships that last. Under pressure for quick results and facing fierce marketplace competition, too many marketers are boxed into spaghetti-to-the-wall forms of digital marketing that limit the potential of their long hours, countless experiments, and warehouses of data. And in the end, they watch their competition sprint ahead. But what if you built a business around long-term relationships with customers, using data to understand who they are, what they need, and where to find more customers just like them? You can. And you?ll leave your competitors, with all of their data and their short-term thinking, to poke around in the scraps.
