Building a strong personal brand online involves establishing your unique values, abilities, and areas of expertise so that others recognize your professional identity. It is important for better business opportunities, job prospects, and partnerships. To develop your personal brand, create a blog and website, be active on social media by posting regularly and engaging with others, set goals to measure your progress, and focus on quality connections rather than just growing your network. Personal branding is about authentically representing yourself, not about privacy or gaming the system for superficial gains.
