Social Commerce

A form of e-commerce in which the entire purchase experience — discovery, evaluation, purchase, and sharing — occurs within a social media platform’s native environment. Includes live streaming commerce (live commerce), shoppable posts, and in-app checkout. Social commerce exploded in China in the late 2010s; by 2026, the US live commerce market is projected to reach $50 billion, with over 17% of all online sales passing through social platforms (Point2Web).

The behavioral mechanism differs from standard e-commerce: social presence (the awareness of others watching and participating in real-time) compresses deliberative friction. Dynamic social proof — live purchase counts, real-time reactions — is perceived as more credible than static reviews because it is temporally fresh and socially embedded. This makes social commerce particularly effective for categories where inspiration and emotional engagement are key purchase drivers.
