Among other viewability challenges, digital marketers are struggling with “unreachable” audiences, and brand “overreach,” says Louise Clements, President at MRM//McCann East. Regarding the former issue, it can be especially problematic when you’re looking at smaller audience segments, Clements told attendees at MediaPost’s Programmatic Insider Summit, on Monday. The solution? A highly programmatic approach that looks at the overall brand, she said. That allows clients to better “supplement” data, and “drive much higher brand awareness,” according to Clements.
