Social media allows for two-way communication between individuals and organizations, moving away from one-to-many broadcasting. It can be used to build personal and professional brands through six stages of engagement, from inactive to content creation. Strategically using tools like blogging, social networking, bookmarking, and photo/video sharing can help connect with others, become a trusted source of information, and share what you know and can do. Transparency, sharing content, acting personally, contributing meaningfully, accepting criticism, and proactive planning and listening are important for brand building on social media.
