This document discusses social commerce and how it relates to e-commerce. Social commerce involves consumers interacting with others during online shopping experiences. Ratings, reviews, recommendations, and referrals provided by consumers can provide value to other consumers and retailers. Social media applications and tools can influence consumers as they progress through the decision-making process. Psychological factors like social proof, authority, and reciprocity also impact social shopping behavior. Best practices for retailers include enabling authentic consumer opinions and making it easy for them to be shared.
