A great paper on the various data and tracking methods that empower you to calculate Marketing ROI. It rightly lists the challenges to calculating it precisely (latency, multiple touches, multiple influencers, extraneous variables...) but also offers variations on the approaches that enable you to calculate a precise return, from single attribution to multi-touch attribution and also using test and control groups. Informative and clear.
