Pandora used billboards in conjunction with geo-fencing in locations near their stores and in regions with a household income of $100,000+ to create brand awareness and reinforce the billboard message with a mobile component.
By combining billboards with geo-fencing, Pandora was able to produce a 135 percent increase over average secondary action rates (SAR) for mobile-only geo-fencing campaigns. Secondary actions are getting consumers to access store information online such as deploying navigation apps for directions to the store, calling the store directly, or accessing additional information about the stores. SAR are considered additional steps of engagement beyond click through rates (CTR).
