Personal branding for CEOs is the deliberate practice of making a company's leader a known, trusted authority in their market, run as a business system rather than an exercise in vanity. Done well, it is measured in pipeline, partnerships, recruiting, and press, not in follower counts, and it starts from positioning, deciding what the CEO should be known for, before any content is posted. The reason it is worth the CEO's time is that buyers, talent, and partners increasingly choose the person they trust, and a visible, credible leader compounds that trust across the whole business. Treated as a vanity project it wastes the CEO's scarcest resource, their time and credibility; treated as a system with clear goals and delegated execution, it becomes one of the highest-return assets a company owns.
