How do you write LinkedIn posts that sound like you?
How to write LinkedIn posts that sound like you
A LinkedIn post stops sounding like you for structural reasons before stylistic ones. Generated posts open with context and a promise ("Last week I learned something about hiring. Here are 5 lessons."), run at an even sentence length, hedge every claim, and close by summarising themselves. Fix those four things and a post reads as human even before you touch vocabulary: put the sharpest concrete claim in the first two lines, vary sentence length hard, commit to the claim, and delete the closing summary.
The first two lines carry most of the outcome, because that is all the feed shows before the "see more" cut. If your specific detail — the number, the mistake, the thing you changed your mind about — is in paragraph four, the post can be perfectly written and still be invisible.
- Put the concrete claim in the first two lines; everything else is stage two.
- Vary sentence length deliberately — even rhythm is the loudest AI tell.
- One idea per post. A list of five lessons is five posts you gave away.
- Cut the closing summary and the hashtag block; neither earns its space.
The four tells, and the fix for each
The warm-up opening: two lines of context before anything happens. Fix it by finding the most specific sentence in your draft and making it the first one. The even rhythm: every sentence between 15 and 20 words. Fix it by putting a four-word sentence next to a thirty-word one, on purpose. The hedge stack: "I think it might be worth considering". Fix it by stating the claim and letting the comments argue. The summary close: a final paragraph that repeats the post. Delete it — the last line should be the last new thing you said, or a genuine question.
None of these are about word choice, which is why prompting for a "casual tone" never fixes them. They are structural, and a model will reproduce them indefinitely unless the structure is specified.
Write from your own numbers, not from a tone word
The reliable way to keep your voice in a post is to measure it once from posts you already wrote and let those numbers constrain the draft: your sentence length and variance, whether you use contractions, whether you open with a question, how much you hedge, the punctuation you actually use. Then the draft starts inside your habits rather than inside the model's.
Use your posts as the sample, not your articles. LinkedIn register is shorter, more first-person and more punctuated than long-form writing, and a profile built from your essays produces posts that read like essays with line breaks.
Length and format that survive the feed
LinkedIn truncates at roughly 1,300 characters, which in practice means a post of 90 to 220 words with real line breaks. Short paragraphs of one to three lines, no wall of text, and no more than three hashtags — the hashtag block at the bottom of a post does nothing for reach and reads as marketing cadence.
Do not put a link in the first version of a post you care about; add it in a comment. And read the draft out loud before posting: the sentence you stumble over is the one the model wrote.
Doing it with StyleMimic
The LinkedIn post generator applies exactly this: your measured profile plus format constraints for the platform — the hook in the first two lines, a target of 90 to 220 words, a live character counter against the truncation point, and a style match score so you can see how close the draft landed before you post it.
It also checks the draft against your own samples, so a high score means the post carries your voice rather than quietly recycling sentences from the posts you pasted. Free account, 5,000 words a month, no card.
Questions
How long should a LinkedIn post be?
90 to 220 words in most cases, which keeps you under the ~1,300 character truncation point with room for line breaks. Longer posts work when the first two lines have genuinely earned the click on "see more".
Do hashtags help reach?
Barely, and a block of them signals marketing cadence. Three at most, or none.
Can I use my own old posts as the style sample?
That is the best sample you have. Paste several of your own posts — same register as what you are about to write — rather than articles or website copy.
