# How to write LinkedIn posts in your own voice

*By Jack Stovell · published 2026-09-20*

LinkedIn has a voice of its own. One-line paragraphs. A hook that promises a lesson. "Here's what I learned." A list of three. A question at the end. It works, in the sense that the format is rewarded, and it has a cost: after a few months of it, your posts sound like everyone else's posts, and nothing like your emails, your newsletter or the way you talk in a meeting.

That gap is measurable, and measuring it is the first step to closing it.

**See the gap.** Paste something that is unmistakably you (a newsletter, a long email), then two or three LinkedIn posts. Each post is scored against the reference piece, with the habits that moved named and numbered.

## What usually moves

Across the posts we have measured, the same features drift: sentence length collapses (the one-line paragraph), contractions drop (LinkedIn prose is oddly formal under the casual surface), questions multiply, and the argument structure flips to conclusion-first even for writers who build to a point everywhere else. None of that is wrong; it is the format. The problem is when the format replaces the voice rather than carrying it.

## Keep the format, keep the voice

The two are separable. A LinkedIn post can be short and still have your rhythm, your contraction rate, your way of opening. The trick is to write from a target: the measured profile of your voice, with the post's structure as a constraint on top. That is exactly the brief ScriptGrain gives a model: 45 measured attributes plus the LinkedIn structure spec, then a score on the draft against the profile.

## If you use an assistant for posts

Give it numbers, not "write a LinkedIn post in my voice". The [prompt builder](https://scriptgrain.com/works-with/chatgpt) turns a sample of your writing into a prompt with your measurements in it; the connector hands ChatGPT or Claude the full profile and scores their drafts. Either way, check the post against the piece that sounds like you before it goes out. Under 0.55 and the format has won.

## Questions

### Should my LinkedIn posts score the same as my newsletter?

Not identically: a 150-word post and a 1,200-word newsletter differ in structure by design, and the score allows for that (short pieces cannot show sentence-length variance). A post that reads under 0.55 against your own writing has lost the voice, not just the length.

### Can I measure a ghostwriter's posts against my own writing?

Yes, that is the founder-and-ghostwriter check: your own writing as the reference, their drafts as the comparisons. The features that moved are the notes to give them.

### Does ScriptGrain write LinkedIn posts?

Yes: LinkedIn post is one of the sixteen content types, with its own structure spec, and every draft comes back with a voice-match score against your profile.
