The Impact of social media On Brand Perception and Consumer Behavior

Owing to the quick advancement in internet technology, particularly the emergence of the Web 2.0 era, social media platforms like Facebook, Twitter, Instagram, WeChat and TikTok have risen rapidly and become an indispensable part of people's daily life. These platforms, with their characteristics of immediacy, interaction and personalization, have changed the traditional mode of information transmission and reception, providing a new channel for communication between brands and consumers. Therefore, this paper explores the relationship between brand perception and consumer behavior under social media through literature analysis. The study found that social media provides brands with more direct, flexible and diversified communication channels, enabling brands to rapidly improve their visibility and consumer recognition in the fierce market competition. Highly interactive social media advertising and consumer platform users' evaluation significantly affect consumers' purchasing decisions. Finally, brands should enhance direct interaction with consumers, leverage the power of social media marketing, create personalized content to increase consumer engagement, and build online brand communities to enhance consumer loyalty. Meanwhile, brands must also pay attention to consumer privacy protection and ensure the transparency and security of data processing to maintain consumer trust.
