LinkedIn Hooks and Post Writing: Formulas, Templates, Examples

#01What makes a LinkedIn hook work?

The feed shows the first few lines of a post, then truncates it. The exact cut-off depends on device and line breaks. Practitioners usually aim to finish the hook within about 140 to 200 characters.

A working hook does three things:

1. Names the reader or their situation ("Finance teams closing in 10+ days").
2. Creates a gap between what they believe and what you will show.
3. Signals substance with a specific number, example or contrast.

#02Which hook formulas can you use?

Use real numbers only. If a figure is from a client, get permission or anonymise it.

#03How should the rest of the post be structured?

Use a simple four-part structure.

What formatting helps on a phone?

• One to two sentences per paragraph, separated by blank lines.
• Numbered steps for processes; short dashes or simple symbols for lists.
• No more than one emoji per section, if any.
• Avoid Unicode "bold" text generators; screen readers often read them badly.
• Tag people only if they are genuinely involved and likely to welcome it.

#04What should you avoid in 2026?

LinkedIn's March 2026 newsroom post said it is reducing engagement bait such as "comment to agree" prompts, recycled low-substance posts and videos that do not match the text.

#05How long should the post be?

LinkedIn does not publish a post character cap on the help pages we checked. Practitioner guidance is to keep most posts to one idea in about 150 to 300 words. Semrush's March 2026 study, run in collaboration with LinkedIn, found the posts most often cited by AI assistants were in the 50 to 299 word range, and that 95% of cited posts were original content rather than reshares. Treat that as a pattern in citations, not proof that length causes reach.

#06How do you edit a draft?

Run this 10-minute checklist before posting:

1. Delete the first sentence if it is throat-clearing ("I've been thinking a lot about...").
2. Read the hook alone. Would your buyer stop for it?
3. Add one specific: a number, a tool name, a quote, a date.
4. Cut adjectives like "game-changing" and "incredible".
5. Check one idea. If there are two, split into two posts.
6. Read aloud. Fix anything you would not say to a customer.
7. Check the close. Is the question genuine?
8. Check facts and permissions for any client or employee mention.

#07How do you write the close?

#08Worked example: Ledgerline

Ledgerline is a fictional accounts-payable software company. Competitors A to D and all figures are illustrative.

Ledgerline's draft post opened: "Excited to share some thoughts on the future of finance automation!" Competitor C's founder posts with specific customer stories.

Walkthrough

1. New hook: "412 invoices unapproved on day 3 of month-end. Here's the rule that fixed it."
2. Context: two lines on why approvals stall when one approver is away.
3. Body: the delegation rule, how it was set up and the result (from 9 days to 2, with the customer's permission).
4. Close: "Controllers: how do you handle approver holidays?"
5. Edit: removed three adjectives and the hashtag wall; added the customer's job title.
6. Result (illustrative): 3.2 times the reach of the original-style posts, with 61% of viewers in finance roles and 27 comments, 11 from controllers.

#09Common mistakes

• Hooks that could have been written by anyone in any industry.
• Burying the specific number in paragraph four.
• Two or three ideas in one post.
• Closing with bait instead of a real question.
• Copying viral templates without your own evidence.

#10Try it yourself

Take your last three posts. Rewrite each hook using a different formula from the table. Run the 10-minute edit checklist on the next post before publishing.

#11Quick quiz

1. What three jobs does a hook do? Answer: Names the reader or situation, creates a gap and signals substance.

2. What did LinkedIn say in March 2026 about "comment to agree" prompts? Answer: It is reducing engagement bait like that.

3. What word range did Semrush find most common among AI-cited posts? Answer: 50 to 299 words.

4. What should you do with a draft that contains two ideas? Answer: Split it into two posts.

#12What should you check before the next lesson?

• A hook formula sheet saved for your team.
• The edit checklist pinned where you draft.
• Your top ten posts ranked by audience quality, not likes.

#13Common questions

How long should a LinkedIn post be? Long enough to make one point well. LinkedIn does not publish a post character cap on the help pages we checked. Most effective B2B posts make a single argument in roughly 150 to 300 words. A Semrush study found most posts cited by AI assistants were 50 to 299 words.

Where does LinkedIn cut off a post with 'see more'? LinkedIn shows the first few lines and hides the rest behind a 'more' link. The exact cut-off varies by device and line breaks, so put your hook in the first one or two lines, roughly the first 140 to 200 characters.

Are engagement bait hooks like 'comment YES' allowed? They are not banned outright, but LinkedIn said in March 2026 that it is reducing engagement bait such as 'comment to agree' prompts. Ask genuine questions instead.

Should I use hashtags on LinkedIn posts? Optionally, a few relevant ones. Profile hashtags were removed in 2024, and LinkedIn's 2026 feed system understands post meaning from the text itself, so hashtags are no substitute for clear topic words.
