One way to improve your personal brand is to make your profile information complete and accurate. Use your profile to show off your set of skills. Be the center of the attention by engaging in community discussions. Remember to talk with sense and work hard to make every post you make useful and worthy to read. Build your brand by showing a great online personality.
Finally, always be appropriate in sharing anything on social media. A funny person is always favored online but being that person will be much nicer if you are also honest, articulate, and real.
