Informational benefits from social media use for professional purposes: Results from a longitudinal study

Using data from four waves of a longitudinal study among Dutch internet users, we examined whether and how the use of social network sites (SNS) for professional purposes is related to informational benefits. Building on a social capital framework and taking into account the affordances of social media, we specifically looked at users' activities and the structure of their online networks. Users of Linkedln or other professional SNS consistently reported higher informational benefits than non-users. The number of ties on the SNS used for professional purposes predicted informational benefits half a year later, and strong ties became more important over time. We also found evidence for a reciprocal relationship between strategic networking and informational benefits. For the use variables (frequency of login, reading, activity in groups, posting professional content), we mainly found concurrent associations with informational benefits. The results shed light on the complex interplay of concurrent and longitudinal processes in the relationship between SNS use and professional informational benefits.
