LinkedIn posts people read. What works as of October 2026.

A business LinkedIn post works best when it carries one useful idea, written in the first person, in 600 to 1,300 characters. The hook goes in the first two lines, which is about 210 characters. The post ends with a single genuine question. That's LinkedIn post best practice in one paragraph. The rest of this guide takes each part in turn and says what to do about it.

The guide is based on Hynca Media Desk's own summary of good practice for business posts, published on 4 October 2026 and drawn from published research on how posts perform on the platform. These rules describe current good practice as of October 2026. They aren't permanent. This guide doesn't say what has changed on LinkedIn or when, because the summary doesn't say either.

If you only have time for one thing, put it into the first two lines. Those 210 or so characters decide whether anyone reads the rest. Most of your effort belongs there. Links and hashtags should stay out of the way.

How long should a LinkedIn post be?

A LinkedIn text post can run to 3,000 characters. The useful range is much shorter: 600 to 1,300 characters.

Here's what that looks like in practice. A 1,300-character post, at the top of the range, uses well under half the limit (about 43%). Only its first 210 or so characters show before "see more". At the bottom of the range, a 600-character post shows roughly a third of itself before the cut. At the top, it shows about a sixth. So even a post of the right length depends on its opening to get the rest read.

Don't treat 3,000 characters as a target. A post that fills the limit isn't more thorough. It's more than twice the top of the range and five times the bottom. If your draft runs past 1,300 characters, it probably holds more than one idea. Cut it down, or split it into two posts on different days.

Most drafting tools and word processors show a character count. Check it before you post. Count spaces and line breaks too.

What should the first two lines do?

Most people see only the first two lines of your post before "see more". That's about 210 characters. Your readers are professionals scrolling a feed, and they decide from those two lines whether to stop.

So the hook goes there. It should tell the reader what the post gives them, in words specific enough that they recognise it's for them. A hook that only teases ("Something surprising happened this week") asks the reader to do the work. A hook that states the useful idea gives them a reason to click.

Here's a practical way to write it:

1. Write the two-line hook first, before the body.
2. Read it with nothing else around it. If it makes sense alone and tells a stranger why to keep reading, it works.
3. Check the length. If the hook runs much past 210 characters, the cut will fall mid-sentence and the point will be lost.
4. Only then write the body, which explains or supports what the hook promised.

If you write the body first, the hook tends to become a summary of it. Summaries make weak openings.

What goes in the body of the post?

One idea. Keep to it.

Write in short lines, with a blank line between paragraphs. Don't use headings. Write in the first person, from the account holder. If the post goes out from a managing director's profile, it should sound like the managing director wrote it. "I" and "we" read naturally in a feed; "the company is pleased to announce" doesn't.

Content that is personal, useful and specific beats promotional content. A post that explains what you learned from a project, or what a change means for your customers, gives the reader something. A post that lists your services asks something of them.

Two things to avoid follow from this. The first is posting a company announcement in the brand's third-person voice, copied from a press release or a website news page. Rewrite it in the first person and lead with what it means for the reader. The second is packing several messages into one post: a new hire, an award and an event in a single block. Pick the one that matters most to your readers and give the others their own posts.

Where do links and hashtags go?

Leave links out unless you're promoting an article. If you are, include the link once, at the end of the post. Don't repeat it, and don't put it in the opening lines where it takes space from your hook.

Use 0 to 3 hashtags. Three is the maximum. Put them all on the last line, after everything else. None at all is fine.

Here's a worked example. An agency shares a client's news piece on LinkedIn. The post opens with a two-line hook that states what the news means for the client's customers. The body explains it in a few short paragraphs, in the first person from the account holder, and ends with a question. The single article link sits at the end. Up to 3 hashtags go on the final line. The reader meets the useful idea first and the link only once they've decided the piece is worth their time.

So avoid a long string of hashtags, hashtags scattered through the sentences, or the same link posted twice.

How should a post end?

End with one genuine question that invites comments. A genuine question is one you'd like answered, and one your readers can answer from their own work. "How does your team handle late invoices?" gives people something to say. "Thoughts?" doesn't.

The guidance holds that saves and comments matter more than likes. That's its view; it gives no data to support it. Still, it's a sensible way to judge your own posts. A post someone saves, or replies to, has done more for them than one they tapped on the way past.

Avoid stacking several questions together. Ask one, and make it the last thing in the post before your hashtags.

Does the same apply to LinkedIn video?

Yes, in a short form. The same principles carry over, with a few video-specific rules.

• Shape: 4:5.
• Length: 30 to 170 seconds. That's half a minute at the shortest and just under 3 minutes at the longest.
• Captions: burn them into the video. Professional viewers often watch with the sound off, so captions matter even more than on other platforms.
• Content: practical and specific, with the personal beating the promotional, just as in text posts.

The caption post that goes with the video follows the text rules. The hook goes in its first two lines. It carries 0 to 3 hashtags, with 3 as the maximum. It should aim for comments and saves, so ending it with one genuine question works here too.

Avoid filming a promotional clip with a voiceover and no captions. With the sound off, a viewer sees moving pictures and no message. A short piece to camera, captioned, explaining one practical idea, does the job the guidance describes.

The guidance gives no file size, resolution, format or caption specifications beyond the 4:5 shape and the 30 to 170 second length. If you need those, check LinkedIn's own help pages before you film. As for the text rules, write the hook first and the rest follows. Whatever you post, a person reads it and decides before it goes out.
