This can include influencing consumer purchasing decisions, political beliefs, cultural trends, and social movements. Social media influencers, who have large followings and high engagement rates, are particularly influential in shaping public perceptions and behaviors. Researchers in this area study how social media influences individuals and societies, as well as the strategies and tactics used by influencers and brands to leverage social media for influence.
