What social listening means
In communication research, Margaret C. Stewart and Christa L. Arnold described social listening in the International Journal of Listening in 2017 as a type of listening and a means of attaining interpersonal information and social intelligence. In marketing, the term refers to a brand listening to what is said about it.
The practical difference from monitoring lies in what is done with the data. Monitoring logs mentions one by one: how many there are, where they appear, which ones need a reply. Listening looks at the whole: which topics recur, which complaints are growing, how the tone shifts after a launch. The same mention serves both. For monitoring, a complaint about a late delivery is a case someone has to answer today. For listening, it is the third complaint this month about the same carrier, and that points to a logistics decision.
Social listening also finds what the brand does not control: user-generated content that does not tag it, an unlinked brand mention in a forum, or a conversation about a competitor. That makes it part of the measurement side of social media marketing.
