Tools like your resume, cover letter, and "elevator pitch" are a few concrete examples to use to market yourself.
Envision your presence like a business card, having the capacity to instantaneously promote the value of your career competencies. Your career value in the eyes of employers increases tremendously when you are able to show not only who you are, but how you made your accomplishments.
Physical and verbal branding is important: with even your photograph missing, potential employers and other contacts would have nothing on which to base a belief in your career competencies.
An active management of your social networking sites is paramount for your branding strategy.
Remember: positive and compelling career branding can take place at any moment during your career development and job search process.
