You spend an hour writing a LinkedIn post. You hit publish. Four likes come in. Two are from colleagues who would like anything you post. The post dies quietly, and you move on.
The hook is almost always the reason. Not the idea. Not the length. Not the time of day you posted. The first two lines failed to earn the click, and everything after them never got read.
This article gives you the specific formulas that stop the scroll, with real performance numbers behind each one.
What a hook actually is
Before you can write a good hook, you need a precise definition of what it does.
A hook is the first one to three lines of your LinkedIn post. It is the text visible before the reader has to click 'see more.' LinkedIn truncates posts at roughly 210 characters on desktop. Everything you write lives inside or outside that window. The hook lives inside it.
A hook has one job: make the reader want to read the next line. Not explain the post. Not summarize what is coming. Not greet the audience.
A hook is not a title. It is not a table of contents. And it is definitely not 'Good morning, LinkedIn.' Those are ways of filling space before you get to the point. The hook is the point.
The only thing a hook needs to do
A hook does not need to explain your post. It needs to create enough tension or curiosity that stopping feels like a small loss.
Why most hooks fail
Five patterns that kill engagement before the reader gets past line one.
The five hook formulas that perform
Each formula comes from analysis of high-performing B2B posts on LinkedIn.
These five formulas come from analysis of high-performing posts across B2B niches on LinkedIn. They are not the only formulas that work. They are the most consistently repeatable ones for beginners. Pick one. Apply it. Do not try to blend two formulas into a single hook.
The counterintuitive claim
State something that contradicts what most people believe. The friction creates a pause.
The specific number
Lead with a precise number. Specificity signals credibility and filters for the right reader.
The confession
Admit a mistake, failure, or embarrassing belief you used to hold. Vulnerability earns attention.
The direct lesson
Front-load the takeaway. Tell the reader exactly what they will learn and why it matters to them.
The pattern interrupt
Open with something structurally unexpected: a very short sentence, a fragment, or a single word that creates a gap the reader wants to close.

These numbers come from different studies with different sample sizes. Treat them as directional, not absolute. Shield Analytics, Taplio, Hootsuite, and Richard van der Blom's annual LinkedIn algorithm research all point the same direction: the first two lines carry disproportionate weight compared to everything else in the post.
If you fix nothing else in your LinkedIn writing, fix the first two lines.
How to write a hook in four steps
A repeatable sequence you can use on every post, starting today.
Find the most surprising thing in your post
Read your draft and ask: what would make someone stop mid-scroll? That sentence, not your intro, is your hook material. It is usually buried in paragraph three.
Pick one formula and apply it
Do not try to combine formulas in one hook. Choose the one that fits the surprising thing you found. Specificity beats cleverness every time.
Write three versions
Write the same hook three ways using three different formulas. You will almost always prefer one immediately. That instinct is usually right.
Cut until it creates tension
Read your best draft and remove every word that does not add friction or curiosity. If a word explains too much, cut it. The hook should raise a question, not answer one.
Do not write the hook first
Most beginners try to write the hook before writing the post. Write the full post first. Then find the most interesting line inside it. That line becomes your hook.
Use AI to draft and test your hooks
Generate volume fast, then apply your own judgment to choose.
AI is useful for generating volume. It is not useful for judging quality. You still need to pick the hook that fits your voice and your audience. Use AI to get to three strong options faster, then apply the four-step process to choose between them.
The prompt below generates five hook variations, one per formula, each under 210 characters. Paste your full post draft where indicated.
Hook generator prompt
Claude / GPT-4Here is a LinkedIn post I have written: [paste your full post]. Generate five different opening hooks for this post. Use one of these five formulas for each hook: (1) A counterintuitive claim (2) A specific number (3) A personal confession (4) A direct lesson with a clear benefit (5) A pattern interrupt using a very short sentence or fragment Each hook should be under 210 characters. Do not summarize the post. Each hook should create curiosity or tension that makes the reader want to click 'see more.' Label each hook with the formula you used.

Only if the hook worked
Line breaks matter more than most writers realize. A single short sentence on its own line creates a visual pause. Two long dense sentences packed into the hook window feel like work before the reader has committed to anything.
On mobile, the character limit drops to roughly 130. A hook that fits comfortably on desktop may get cut mid-sentence on a phone. Test your hook by pasting it into the LinkedIn app on your phone before you publish. If it reads cleanly and creates tension at the cut point, it works. If it gets cut in the middle of a thought, trim it.
Common questions from beginners
Direct answers to the four questions that come up most often.
Does a strong hook feel manipulative?
A hook is not a trick. It is a promise. If your post delivers on what the hook sets up, you have done your job.
Clickbait fails because the body does not deliver on what the hook implied. A strong hook paired with a strong post is just good writing. The reader clicked, read, and got what was promised. That is the outcome you want.
Should every post have a hook?
Yes, if you want people to read it. The only exception is a post so short it has no 'see more' truncation at all. For anything longer than three sentences, the hook carries the weight of the entire post.
Even short posts benefit from a strong first line. A weak opener on a short post still signals low effort to the reader before they decide whether to engage.
Do hooks work the same way in every industry?
The formulas work across industries. The specifics change. A counterintuitive claim in HR sounds different from one in finance or supply chain. The formula is the structure. You fill it with the specific language, data, and context your audience recognizes.
A specific number hook in cybersecurity might read: 'We audited 47 SaaS vendors. 31 had this misconfiguration.' The same formula in recruiting reads differently but works for the same reason: specificity signals that the writer did real work.
What if nothing in my post feels interesting enough to hook?
That is a signal about the post, not about your ability to write hooks. If you cannot find one surprising, specific, or counterintuitive thing in your draft, the post may not have a clear point yet.
Go back to the draft and ask: what is the one thing I want the reader to remember? Write that sentence. Then ask: what would make someone who does not know me care about that sentence? The answer to the second question is your hook.
