According to an interview with Glenn Engler, CEO of Digital Influence Group, a full-service digital agency, the core of everything that they do is Social Media.
Helping companies integrate social media into their digital campaigns and online presence brings with it a certain level of intimacy with the client and even requires the agency to make recommendations, not just about marketing and advertising but also about internal operations, processes, and businesses goals.
For this reason, the rising demand for social media engagement highlights another step that agencies are taking—and must take—towards becoming true business partners with their clients (and even, at some level, competing with business consultancies).
