LinkedIn Hooks: First Lines That Stop the Scroll

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 2,400+ LinkedIn creators into five styles, and compared each person against their own other posts, we found something different. Four of the five made no reliable difference 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 July 2026 data 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 reliable difference. Two did worse than the writer's ordinary openers.

How much each opening style helped or hurt a person's typical post

Tactic	Reactions vs their own posts	Change in reactions	Creators tested	Who benefited
First person (I, my, we, our)	1.19×	+19%	1,734	69%
A number anywhere in the first line	1.08×	+8%	1,772	61%
Starting with a number	1.05×	+5%	288	57%
Contrarian ("unpopular…")	0.98×	−2%	398	47%
Direct address ("you")	0.90×	−10%	1,382	35%
Question hook	0.83×	−17%	685	31%

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 used I, my, we or our earned about 19% more reactions than the same person's other openers. We measured that across 1,734 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 one of only three clear wins in our whole LinkedIn algorithm study, alongside attaching an image and telling a personal story. Posts where the writer described something they actually did, saw or went through earned about a third more reactions than the same person's other posts, and that worked for 3 in 4 people.

We checked this one harder than anything else on the page when we first ran it in July 2026, 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 only moves engagement a little anyway.
• It is not one format carrying it. Split three ways it held 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 17% fewer reactions than the same person's other openers, across 685 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 only about half a comment, while costing about 7% of reactions, across 924 people. Questions let you down at both ends, which is awkward for the most repeated tip on LinkedIn.

The same goes for the other bait people put at the bottom of a post. "Comment GUIDE and I'll send it to you" used to work, but since July 2026 those posts have earned about 24% fewer reactions than the same person's other posts. If you are offering something, share the link instead.

Opening with a question cost about 17% 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 real difference. Contrarian openers built on stop, never, nobody, wrong or unpopular came out within about 2% of the same person's other hooks, across 398 people. 47% did better and 53% did worse, which is close to 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?

It depends what you mean by "start with". A number somewhere in your first line helps a little: about 8% more reactions than the same person's other first lines, across 1,772 people, and 6 in 10 of them did better. We saw the same small bump in both our July and October runs. But making the number the very first word made no reliable difference, across 288 people.

So the practical version: if you have a specific figure, get it into the first line, where it does its job of being concrete. Don't twist the sentence just to lead with the digit.

MagicPost's analysis of 1.2 million posts found first lines containing a number earn 35 likes against 26 for those without one. We agree on the direction. The size is the difference: theirs compares posts by different people, so part of that gap measures who writes number-led hooks. Compared within the same person, the bump is real but small. (Our first version of this page, in July, only tested numbers as the opening word and reported no effect. Testing a number anywhere in the line is the fairer match for their claim.)

Should you write "you" in a LinkedIn hook?

Openers built on you and your, the "You need to stop doing this" shape, cost about 10% across 1,382 people. Only about 1 in 3 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:

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 mostly 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.

1. 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.
2. Delete the question mark. Not at the start, not at the end. Ask when you genuinely want an answer, not as an engagement tactic.
3. Stop turning the opener around on the reader. "You need to" costs about 10%. The same point made in the first person does not.
4. Drop the formula. Contrarian phrasing came out at nothing, and stat-led openers at no reliable effect. That time is better spent on the thing you are actually reporting.
5. Write the first line to the length the sentence needs. No length band beat any other.
6. 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. 2,400+ English-speaking B2B creators between 1,000 and 500,000 followers, individuals only, spread across region and audience size. Their posts were collected in two sweeps, in July and October 2026, and every test on this page was re-run on the latest twelve months, October 2025 to September 2026. 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 115,000+ posts with text in the study rather than all of them. We checked the extraction before classifying anything: in the July 2026 data 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 116,000+ posts, which tested the most repeated LinkedIn rules the same way. See also how long a LinkedIn post should be and every LinkedIn character limit.
