"Half the money I spend on advertising is wasted; the trouble is I don't know which half." - John Wanamaker. This age-old quote is as true today as ever. Facebook will tell you that every other conversion happening on your site is because of their ads. So will Google. So will your TV agency. How can you develop a framework to judge true incrementality of your marketing spend, and based on it, set optimal spend levels for each channel? Based on the case study of Grubhub, the nation's leading food delivery company that sells $5B worth of food a year and grows the active diner base 67% YOY, we'll explore practical, no-nonsense means to drive measureable growth.
