What is a voice profile, and why does your LinkedIn writing need one?

A voice profile is a written description of how you actually write, built from work you have already published rather than from how you would like to sound. That distinction is the entire point. Most people's idea of their own voice is a flattering guess, and guesses are what produce drafts that feel slightly off without anyone being able to say why.

What goes in it

• Sentence length and rhythm, including how often you break your own pattern. A writer who runs long and then cuts to four words reads completely differently from one who is consistently medium.
• Vocabulary you reach for, and vocabulary you never touch. The second list is usually more useful than the first.
• How you open: with a scene, a claim, a number, or a question. Most people do one of these far more than they realise.
• How you close, and whether you ask real questions or rhetorical ones.
• Formality markers: contractions, slang, field jargon, whether you swear, whether you use first person plural.
• Recurring subjects and the position you usually take on them, so a draft does not accidentally argue against something you have defended for two years.

Why it beats a style guide

A style guide describes intentions. A voice profile describes evidence. When a ghostwriter, an assistant, or a model writes on your behalf, intentions are unenforceable and evidence is checkable. "Warm but professional" produces twenty different drafts from twenty different people. "Opens with a scene, uses contractions, never says leverage, paragraphs of one to three sentences" produces roughly the same draft from all of them.

There is a second benefit that is easy to miss. Once your voice is written down, disagreements become concrete. Instead of sending back a draft with "this doesn't feel like me," you can point at the rule it broke, which is faster for everyone and stops the same correction happening every month.

How to keep it accurate

Voices move. You change clients, you get more confident, you get bored of a format. A profile built from posts you wrote two years ago will slowly start pulling your writing backwards, which is drift in the other direction and just as annoying.

Review it every few months against your ten most recent posts. In Run More Posts, each observation can be marked as wrong, and once flagged it is not applied again, so the profile converges on how you write now rather than how you used to.
