Is social marketing just marketing using social media?
No.
Social networking tools and technologies are increasingly popular ways to reach an audience and spread a message, but it's important to distinguish this 'social media marketing' from social marketing.
Social marketing is an approach used to develop activities aimed at changing or maintaining people’s behaviour for the benefit of individuals and society as a whole. It is a recognised discipline now found in academic courses, textbooks and several dedicated, peer-reviewed journals, with a regular programme of international conferences.
Social media may be part of the toolkit for engaging with certain audiences, but the distinction is very important. For those of us working in social marketing this presents serious issues around integrity, authority, and possibly even ethics, which need to be addressed.
How does social marketing fit with behavioural economics?
In recent years a number of books, including Nudge, Freakonomics, The Tipping Point, The Spirit Level etc., have been picked up by policy makers and political parties. These are seen as offering new thinking and approaches to behaviour change and health inequalities and as possibly offering answers to some of the challenges facing society.
These offer a view of society through the lens of behavioural economics, which attempts to address the shortcomings of traditional, or neoclassical economics, with more of an emphasis on insight and a psychological view of the often irrational behaviour of individuals and groups.
