By Charles Summers · Updated · Free, no signup
Short answer
This diagnoses what is weak about your LinkedIn draft opener (a low-curiosity phrase, a missing number, or a line that runs past the desktop truncation point around 210 characters) and rewrites it 8 ways using 8 named hook patterns: contrarian, specific-number, confession, before/after, question, list-tease, pattern-interrupt, and stakes. Every rewrite gets an exact character count and a flag if it will be cut off.

It runs entirely in your browser. Nothing you type is sent to a server, no account is required, and there is no usage limit, because there is no cost per run to control.
The truncation point is the whole game
LinkedIn shows a fragment of your post in the feed and hides the rest behind see more. On desktop that fragment is roughly the first 200 characters, and in the mobile app it is closer to 140. Since most sessions happen on mobile, the honest planning number is the shorter one. Everything after the cut is invisible until someone chooses to expand, which means the first line is not an introduction to your post. It is the advert for it, and it is the only part most of your audience will ever read.
The budget is smaller than the character count suggests, because layout eats it. Every line break consumes a line of the visible window whether or not the text fills it. Emoji occupy width and sometimes count for more than one character. A name tag, a long URL, or a leading date all burn space that could have carried the idea. Two short lines of eight to twelve words each is the shape that survives on both platforms, and it is worth writing to that constraint deliberately rather than discovering it after publishing.
The other consequence people miss: the preview is generated from the top of your text, so the classic essay structure works against you. Context first, then setup, then the interesting bit in paragraph four is a fine way to write and a terrible way to be seen. If the sharpest sentence in your draft is at the bottom, the rewrite is usually just moving it to the top and letting the rest of the post explain it.
What actually makes someone tap see more
Expansion happens for one of a small number of reasons, and none of them is that the writing was pleasant. The reader either recognises a situation as theirs, encounters a claim they want to argue with, or is left holding an incomplete thought that is annoying to leave unresolved. Those are the mechanisms. The patterns below are just reliable ways of triggering them, and they work across topics because they operate on attention rather than on subject matter.
- The specific number. We rewrote 240 landing pages last year. Nine of them mattered. Precision reads as first-hand experience, and the gap between the two numbers creates the question the post answers.
- The contradiction of received wisdom. State the thing your audience believes, then say it is wrong. This works because disagreement is a stronger motivator than curiosity, and the comments it produces feed distribution.
- The named cost. That integration took four months and cost us two enterprise renewals. Consequences are concrete in a way that lessons are not, and they license the rest of the post to be advice.
- The unfinished sentence. Open mid-situation with no setup. The client asked one question in the QBR and the room went quiet. The reader has to expand to resolve it, which is the entire job of a hook.
- The direct address to a narrow group. If you run demand gen at a company under fifty people, this is your quarter to fix attribution. A smaller named audience produces better engagement from that audience than a broad appeal produces from anyone.
The distribution mechanics sitting behind the hook
A hook is not a vanity exercise, it feeds the ranking. Tapping see more is an explicit engagement signal and it extends dwell time, and dwell time is one of the strongest inputs into whether the feed shows your post to more people. A post that gets a modest number of expansions early can outperform one that got more passive impressions, because the platform is reading the ratio rather than the raw count.
The first sixty to ninety minutes matter disproportionately. Early engagement determines whether distribution widens beyond your immediate network, which is why posting and then leaving for a meeting reliably underperforms posting and answering comments. Comments and replies carry more weight than reactions, so a hook that provokes a specific disagreement is doing more work than one that merely gets approving nods.
On outbound links, the safest read of the evidence is that links in the post body do not help reach and may hurt it. The common workaround is putting the link in the first comment and editing it into the post later. Whether or not the suppression is as strong as practitioners believe, the behaviour costs you nothing, so treat it as cheap insurance rather than a settled fact.
Rewriting a draft without turning it into bait
The failure mode on the other side of a weak hook is a hook that oversells. If the first line promises a dramatic story and the post delivers a mild observation, you get the expansion and lose the reader immediately, and the platform sees a short dwell time despite the click. Repeat that pattern and you train your own audience to scroll past your name. A hook is a promise with a delivery date about four lines later, and the post has to pay it.
Practical process for a rewrite. Find the single most surprising true sentence in the draft, wherever it sits. Strip it of qualifiers, hedges and job titles until it can stand alone. Put it first. Then check the two lines against the shorter mobile limit by counting characters rather than trusting your eye, since a desktop preview will flatter you by around sixty characters. Finally read line one on its own and ask whether it would still make you stop if a stranger had written it.
Match the hook to tone as well as topic. A blunt contrarian opener under a sincere post about a redundancy reads badly, and the mismatch is more noticeable on LinkedIn than on other platforms because the audience is professional and often includes people who know you. Consistency across posts compounds too: an account with a recognisable voice earns expansions on the name alone, which is the only durable advantage available in a feed.
Numbers worth knowing
| Metric | Typical | What it means |
|---|---|---|
| Desktop truncation point | about 200 characters | Varies with window width and font settings, so treat it as a range rather than a hard limit. Never write right up to it. |
| Mobile truncation point | about 140 characters | The number to actually write to, since most sessions are mobile. A hook that only works on desktop is a hook most of your audience never sees. |
| Usable first-line length | 8 to 12 words | Leaves room for a second line before the cut. Line breaks and emoji spend this budget faster than the character count implies. |
| Window that decides distribution | first 60 to 90 minutes | Early engagement rate governs whether the post travels beyond your network. Posting and then going offline wastes the only window that compounds. |
Mistakes that quietly cost you results
- Putting the interesting part in line four
- Nobody sees line four unless line one earned the expansion, so a good post structured as an essay simply does not get read. Move the sharpest true sentence to the top and let the rest of the post explain it.
- Opening with excited to announce
- It signals a company update, which trained readers scroll past automatically, and it spends the entire visible window on nothing. Lead with what changed for the reader and put the announcement in line three.
- Writing a hook the post does not pay off
- Overselling gets the expansion and then loses the reader in seconds, which reads to the feed as low dwell time and teaches your audience to ignore your name. Promise only what the next four lines actually deliver.
- Spending the first line on context or credentials
- After 12 years in B2B SaaS, I have learned... uses the entire mobile preview on setup nobody asked for. Credentials belong further down where they support a claim you have already made interesting.
- Burning the preview on line breaks and emoji
- A decorative opening line, a blank line and an emoji can consume most of the visible window before a single idea appears. Count characters against the mobile limit rather than judging by the desktop preview.
What does the output look like?
This is the exact output the tool produces from the example inputs. It is generated by the same code that runs when you click the button, so what you see here is what you get.
Frequently asked questions
How many characters can a LinkedIn hook be before it gets cut off?
On desktop, LinkedIn truncates a post behind "see more" at roughly 210 characters, though the exact point shifts slightly by device and font. This tool flags any hook over 210 characters so you know it is relying on a reader tapping "see more", which most scrollers will not do. Mobile truncates even earlier, so treat 210 as a ceiling, not a target.
Why is "I'm excited to announce" considered a weak opener?
Because it tells the reader the post is about you before it has earned their attention, and "excited" is one of the most overused words on the platform, so it reads as noise. The scroll-stopping test is simple: would a stranger keep reading if the first six words were the only ones visible? "I'm excited to share" fails that test every time.
Do numbers actually make hooks perform better?
Yes, and the reason is specificity, not the number itself. "We improved outbound" is a claim. "We cut cost-per-meeting by 37% in 90 days" is a result. Readers scroll past claims automatically because everyone makes them, but a specific number signals there is a real story behind it, which is what earns the click to expand.
Should every post use the same hook pattern?
No. Repeating one pattern (contrarian, for example) trains your audience to recognise and skip it once the novelty wears off. Rotate between the patterns based on what is actually true about the post: use before/after only when you have a real before-state, use specific-number only when the number is real, and never force a pattern onto content it does not fit.
