Shaun Koiner, Chief Product Officer of Perform Media, discusses strategies for publishers to succeed across mobile platforms. He argues that apps, mobile web, and social media like Facebook should work together, not be viewed as separate. Publishers need to focus on millennials' app usage behaviors and consider all touchpoints where users consume content like apps, mobile web, and social media. The most engagement comes from apps, but mobile web still has a role to play along with notifications, personalization, and monetization across platforms.
