What is LinkedIn personal branding?

The phrase sounds like self-promotion, and the version that is self-promotion does not work. What does work is narrower: being reliably useful about one subject, in public, for long enough that people know what you are the person to ask about.

The commercial argument is straightforward. Buyers research people before they research companies, and a profile with a visible track record of thinking shortens every conversation that follows. It is also durable in a way that company-page reach is not.

It is slower than it looks from the outside. Most people who appear to have grown quickly were posting into near-silence for several months first, and the accounts that never compound are usually the ones that stopped during that stretch.

The profile is part of the work, not an afterthought. Every post that lands sends some readers to the profile, and a headline and About section that name the same subject the posts keep returning to is what converts that visit into a follow. A strong post pointing at a profile that says nothing loses the reader it just earned.

Measure it by what it produces rather than by follower count. Profile views after a post, inbound messages that reference something you wrote, and the seniority of the people commenting are the signals that the association is forming. A small audience of the right readers produces opportunities a large general one never will.

It is also personal in a way that is easy to underestimate. The audience follows a person, which means it does not transfer cleanly to a company, a successor, or a rebrand.
