Success can be its own worst enemy, which is why smart marketers mix it up and shift strategies to take advantage of new partners and new approaches. But what are useful guidelines to follow when choosing and vetting a DSP, and how many is too many? Our host Peggy Anne Salz runs through best practices with Kurt Geater Mobile Marketing Manager at Groupon,  the worldwide e-commerce marketplace that connects subscribers with local merchants by offering activities, travel, goods and services. Kurt, a Mobile Hero recognized for his app marketing achievements, also draws from his earlier career experience working at a DSP to highlight what marketers need to watch before they take the plunge. He also offers us his take on channels such as Reddit and weighs on the 2019 trends that will have lasting impact and importance into 2020.
