LinkedIn Hooks: First Lines That Stop the Scroll
By Sam Cassman · Last verified
What makes a good LinkedIn hook? Writing in the first person. Across 2,500 LinkedIn creators, opening with "I", "my" or "we" earned about 20% more reactions than the same person's other openers, and it worked for about 7 in 10 of them. The contrarian, statistic and question openers that hook guides teach did nothing, or made things worse.
Are you trying to work out what to put in the first line of your LinkedIn post? You are not alone, and the advice is unusually loud on this one. Open with a contrarian take. Lead with a number. Ask a question. Keep it short and punchy. Almost none of it arrives with any evidence attached, and the people repeating it rarely show their working, so we decided to test the formulas properly.
Most people believe a good hook is a trick you can learn, and that the right opening line will do the heavy lifting. When we sorted the first lines written by 2,500 LinkedIn creators into five styles, and compared each person against their own other posts, we found something different. Four of the five made no difference at all or actively cost engagement. The only opener that earned more was the one with no formula in it: writing about yourself.
In this article we'll cover what a hook actually is and how much of it people see, which of the five opening styles earned more and which lost, why questions let you down at both ends of a post, and what to write in your own first line instead. Read on to find out more.

What is a LinkedIn hook?
Your hook is the first line of your post: everything before your first line break. It matters more than the rest of what you write, because LinkedIn hides almost all of it. Only about 210 characters on desktop and 140 on mobile show before the "…see more" link, and everything past that point is something the reader has to choose to open.
That fold is the tightest of LinkedIn's character limits that actually changes how you write.
In our sample the typical first line ran to 75 characters, with most between 49 and 129. So the average hook uses around a third of the space it gets before the fold.
That much is uncontroversial. The interesting question is what you should put in it.
Which LinkedIn hooks actually work?
We sorted first lines into five styles and compared each person's posts using a style against their own posts that did not. One style earned more. Two made no difference whatsoever. Two did worse than the writer's ordinary openers.
Reactions, compared with the same creator's other posts
Table view
| Tactic | Reactions vs their own posts | Change in reactions | Creators tested | Who benefited |
|---|---|---|---|---|
| First person (I, my, we) | 1.20× | +20% | 1,790 | 69% |
| Contrarian ("unpopular…") | 1.00× | No change | 365 | 48% |
| Number or stat in the hook | 1.00× | No change | 170 | 51% |
| Direct address ("you") | 0.91× | −9% | 1,303 | 38% |
| Question hook | 0.85× | −15% | 446 | 32% |
That shape is the finding. If hook formulas worked the way they are taught, this chart would be a staircase of clever techniques beating plain writing. Instead the only one that wins is the one that asks you to have done something worth describing.
Do first-person LinkedIn hooks perform better?
Yes, and it is the most reliable thing we know about first lines.
Posts whose first line opened with I, my, we or our earned about 20% more reactions than the same person's other openers. We measured that across 1,790 people, and about 7 in 10 of them did better. If your posts usually get 30 reactions, that is the difference between 30 and about 36.

It is the second-biggest win in our whole LinkedIn algorithm study, behind only attaching an image.
We checked this one harder than anything else on the page, because our first assumption was that it had to be something else in disguise.
- It is not really about images. First-person posts carried an image 56% of the time, and so did everything else. No difference.
- It is not really about length. They ran to about 1,060 characters against about 1,040 for other posts, and post length barely moves engagement anyway.
- It is not one format carrying it. Split three ways it holds in each: about 22% more on text posts, 18% on image posts and 13% on video posts, with roughly 6 to 7 people in every 10 benefiting each time.
So what is left is the writing itself. LinkedIn readers reward a post that sounds like a person describing something that happened to them, and they decide that from the first line.

Same subject, same information, same length. The second version of each simply reports something the writer did. So before you reach for a formula, check whether your first line could just say what happened to you.
Do question hooks work on LinkedIn?
No. Opening with a question was the worst style we tested: about 15% fewer reactions than the same person's other openers, across 446 people, and only about 3 in 10 of them did better. If a question opener is your habit, this is the single easiest thing on this page to change.
Three separate studies, using three different methods, land on the same answer. AuthoredUp's analysis of 309,614 posts ranked question openers last of the five styles it tested, at 2.16% median engagement against 2.60% for story openers. MagicPost, looking at 1.2 million posts, found first lines that ask a question earn 19 likes against 29 for everything else.
It also fails at the other end of the post. We separately found that ending with a question earned a typical gain of no extra comments at all, while costing about 10% of reactions, across 723 people. Questions let you down at both ends, which is awkward for the most repeated tip on LinkedIn.
Opening with a question cost about 15% of reactions. Only 3 in 10 of the people who tried it came out ahead.
The reason is not mysterious. A question asks the reader to do work before you have given them anything. A first-person opener does the opposite: it hands over a fact, and lets them decide whether they want the rest.
Do "unpopular opinion" hooks work on LinkedIn?
They made no difference at all. Contrarian openers built on stop, never, nobody, wrong or unpopular matched the same person's other hooks exactly, across 365 people. 48% did better and 52% did worse, which is a coin flip. So if you are writing "Unpopular opinion:" out of habit, you can stop without losing anything.
The claims made for it are not modest. Postiz says the "Unpopular opinion:" opener can triple engagement. Across the people in our sample who actually use it, it moved their typical post by nothing.
To be fair to the technique, the largest outside dataset disagrees with us here. AuthoredUp ranked contrarian openers second best of the five styles it tested, at 2.31% median engagement. Theirs compares posts by different people, so it partly measures who writes contrarian hooks in the first place; ours compares each person against themselves. We would rather show you the disagreement than hide it.
Should you start a LinkedIn post with a statistic?
Also no difference at all, across 170 people. Almost exactly half did better and half did worse. If you have a striking number, use it because it is the point of the post, not because you think the opening slot rewards it.
This is the one hook finding where a serious study disagrees with us, and it deserves saying out loud. MagicPost's analysis of 1.2 million posts found first lines containing a number earn 35 likes against 26 for those without one.
The methods differ in a way that explains the gap. Theirs compares posts by different people, so it partly measures who writes stat-led hooks. Ours compares each person against themselves, and within a person the effect disappears. We think ours is the fairer test, but 170 people is our smallest hook sample, so treat this one as a strong hint rather than a settled answer.
Should you write "you" in a LinkedIn hook?
Openers built on you and your, the "You need to stop doing this" shape, cost about 9% across 1,303 people. Only about 4 in 10 did better, the second-worst hit rate on this page.
It is the mirror image of the first-person finding, and together they are the clearest signal in this data: write about yourself, not at the reader. The good news is that the same sentence usually turns around at no cost.

How long should a LinkedIn hook be?
There is no length that wins, so this is one rule you can stop worrying about. Compared with first lines of 40 to 80 characters:
| First line length | What happened |
|---|---|
| Under 40 characters | About 7% more reactions |
| 40 to 80 characters | Our comparison point |
| 80 to 140 characters | No difference |
| 140 characters and over | About 8% more reactions |
Short openers and long openers both come out marginally ahead of the middle, which is not a pattern, it is noise. "Keep your first line short" has no support in our data, and neither does its opposite.
That matches what we found in the body of the post, where chasing an ideal post length turned out to be measuring images and account size rather than length. Write the first line the length your sentence needs.
How do you write a better LinkedIn hook?
In order of how much our data supports it.
- Start with something you did. "I", "my", "we". It is the only style that beat a person's own baseline, and it worked for about 7 in 10 of them.
- Delete the question mark. Not at the start, not at the end. Ask when you genuinely want an answer, not as an engagement tactic.
- Stop turning the opener around on the reader. "You need to" costs about 9%. The same point made in the first person does not.
- Drop the formula. Contrarian phrasing and stat-led openers both came out at nothing. That time is better spent on the thing you are actually reporting.
- Write the first line to the length the sentence needs. No length band beat any other.
- Then attach an image. It is worth about a third more reactions, more than any hook, and the two work independently of each other. The detail is in the full algorithm study.
How we tested LinkedIn hooks
The same method as the rest of our research, and the same limits.
Who we looked at. 2,500 English-speaking B2B creators between 1,000 and 500,000 followers, individuals only, spread across region and audience size. All their posts collected in a single sweep in July 2026, covering the previous twelve months. Reshares excluded. Nothing counted until a post was at least 14 days old. We use typical figures (medians) rather than averages throughout, so one viral post cannot drag a result upward.
How we defined the hook. The first line means the text before the first line break. Posts with no line break at all were excluded, as were image-only posts with no text, so this analysis runs on a subset of the roughly 86,000 posts in the study rather than all of them. We checked the extraction before classifying anything: the typical hook ran to 75 characters, with most between 49 and 129.
How we tested. Every number on this page compares a person against themselves, with at least four posts on each side of the comparison. People who tied exactly are left out of the "who did better" percentages rather than counted as losses. Sample sizes differ by style, because not everyone writes every kind of hook, and they are stated with each finding.
What this page cannot tell you. Three things, honestly.
This page is one finding from our LinkedIn algorithm study of 130,000 posts, which tested eleven common rules the same way. See also how long a LinkedIn post should be and every LinkedIn character limit.

Frequently asked questions
- What is a LinkedIn hook?
- The first line of your post, meaning everything before your first line break. It carries the whole post, because only about 210 characters on desktop and 140 on mobile show before the '…see more' fold. In our sample the typical first line ran to 75 characters.
- What makes a good LinkedIn hook?
- Writing in the first person. Posts whose first line opened with 'I', 'my', 'we' or 'our' earned about 20% more reactions than the same person's other openers, across 1,790 people, and about 7 in 10 of them did better. It worked on text, image and video posts alike.
- Do question hooks work on LinkedIn?
- No. Opening with a question was the worst style we tested: about 15% fewer reactions than the same person's other openers, across 446 people, and only about 3 in 10 did better. Ending with a question does not help either.
- Do 'unpopular opinion' hooks work on LinkedIn?
- They made no difference at all. Contrarian openers built on 'stop', 'never', 'nobody', 'wrong' or 'unpopular' matched the same person's other hooks exactly, across 365 people, with 48% doing better and 52% doing worse. That is a coin flip.
- Should you start a LinkedIn post with a statistic?
- It made no difference in our data, across 170 people. That is our smallest hook sample, and MagicPost found the opposite when comparing posts by different people, so this is the one hook finding where a serious study disagrees with us.
- How long should a LinkedIn hook be?
- There is no length that wins. Compared with first lines of 40 to 80 characters, shorter ones earned about 7% more and longer ones about 8% more, which is noise rather than a pattern. The 'keep your first line short' rule has no support in our data.
- Do LinkedIn hook formulas work?
- Four of the five styles we tested did nothing or cost reactions. The only one that worked was writing in the first person, which is a habit rather than a formula: it means the post is about something you actually did.

I'm Sam. I built Flypost after watching too many good businesses sit on years of material (blog posts, call transcripts, case studies, half-finished decks) and post almost none of it.
I write everything here myself. When I claim something works on LinkedIn, it's because I tested it first-hand or ran the numbers across our own data. Where I'm working from a small sample, I'll say so. I'd rather be useful than certain.
