When customers keep their activity online, this attribution is easy to track. Even activity across multiple devices can be properly attributed to its source marketing content. But things change when customers leave the digital realm: Offline marketing results are more challenging to accurately attribute. Too often, marketers are forced to either estimate the offline impact of their SEM, social and other digital campaigns, or they don't factor them in at all.
This creates a distorted view of how these channels are driving returns on investment (ROI). Accuracy in measuring ROI is essential in helping you know how to allocate your resources. Fortunately, improved approaches to offline marketing make it easier to pin down concrete numbers.
