To achieve key business goals with omnichannel programs, digital strategy professionals need to ensure that they have the right metrics in place.

This report lays out the core categories of omnichannel metrics, recommends how to align them with business objectives, and offers a step-by-step process for collecting and using these metrics. This is an update of a previously published report; Forrester reviews and revises it periodically for continued relevance and accuracy.
