Despite glum predictions, US retailers saw steady growth in 2017 and finished with a record-breaking $598 billion holiday season, proving once and for all that retail is not dead. Even e-Commerce colossus Amazon is making concerted moves into retail.

In spite of its growth, tracking and proving retail marketing ROI can pose a challenge for marketers. This piece will explain how to set the right goals, gather the pertinent information, and provide your clients with detailed and practical insights that prove your retail marketing ROI.

Before you get started, keep in mind that you can't prove ROI without first setting a performance baseline. This can be tricky in retail, so make sure that you ask your client whether or not they have records of in-store activity, such as foot traffic, sales (both number and volume) and promotions that you can combine with the information from the online side of their business.
