Why does the first line of a LinkedIn post matter so much?

In the feed, LinkedIn shows only the first line or two of a post before a "…more" link, so the opening line is the only part most people read. If it does not earn the click, the rest of the post is never seen. That is why the hook is written and tested separately from the body.

How long should a LinkedIn hook be?

Short enough to show in full before the fold on a phone: one line, roughly 6–16 words. The checker scores LinkedIn hooks against that range. A second short line can carry the open loop; a long first paragraph gets cut mid-sentence.

What LinkedIn hooks should I avoid?

Openers that announce the post ("I'm excited to share…", "Thrilled to announce…"), generic statements with no specific detail, and questions whose answer is obviously yes. Lead with a specific number, a concrete scene from your work, or a claim your audience will want to argue with. The checker flags the vague and cliché patterns.

Free LinkedIn Hook Generator

Write the first line of a LinkedIn post that earns the "see more" click: eight hooks for any topic, scored for length, specificity and opener strength. Check your own too.

Your topic

LinkedIn hook examples, scored

These are 64 original hooks, eight for each of eight platforms, with one hook per mechanic: question, statistic, story, bold claim, counterintuitive, empathy, curiosity and urgency. Each is scored live by the checker above, so the number next to it comes from the same rules published on this page. The line under each hook names the mechanism so you can reuse it for your own topic.

From these 8 examples: median hook score 68/100; Question hooks score highest on average (85) and Empathy hooks lowest (55); 25% of the examples are under 12 words. Computed by the checker on this page at render time.

Question
85/10013 words
How many of your clients would hire you again tomorrow if you asked?
Why it works: Forces an honest self-count the reader cannot do without thinking.
Statistic
60/10012 words
[Number]% of my meetings last quarter could have been a two-line message.
Why it works: A personal figure that invites readers to compare their own calendar.
Story
75/10016 words
I got rejected from a role on Monday and referred for a better one by Friday.
Why it works: A reversal in one week; the reader wants the middle of the story.
Bold Claim
60/10013 words
A newsletter with two hundred readers is worth more than ten thousand followers.
Why it works: Ranks two things the reader values in an order they may not expect.
Counterintuitive
60/1008 words
My worst-performing post brought in my best client.
Why it works: Separates reach from results, which contradicts how most people judge posts.
Empathy
55/10016 words
Learning a new skill at thirty-five feels slower because you finally know what good looks like.
Why it works: Reframes a private frustration as a sign of progress.
Curiosity
75/10011 words
The one spreadsheet column that changed how I price my time.
Why it works: A tiny, specific object with an outsized promised effect.
Urgency
85/10015 words
If you sit for eight hours today, the ten-minute walk at lunch is not optional.
Why it works: Anchors the advice to today's schedule rather than someday.

How the hook score works

The checker is deterministic and runs in your browser: the same hook always gets the same score, nothing is sent to a server, and no AI model is involved. Points are added for each rule below, clichés subtract, and the total is clamped to 0–100. The same scorer rates every generated hook and every example on this page.

+25
Length fits the platform's word range (TikTok/Reels/X 4–12, YouTube 6–14, LinkedIn 6–16, blog/email 8–20, essay 10–25). Points fall by 5 for every word outside the range.
+20
A hook mechanic is detected — question, statistic, story, bold claim, counterintuitive, empathy, curiosity or urgency — rather than a plain statement.
+15
Specificity: the hook contains a number, a proper noun or a concrete measurable such as a timeframe, an amount or a distance.
+15
Strong opener: the first three words contain a verb, a number, "you" or a question word — that is all a reader sees before deciding.
+10
Second-person address: the hook speaks to "you".
+15
Open loop that fits: a question, curiosity or counterintuitive hook that stays under the platform's upper word bound.
-5 each
Each cliché or filler phrase ("in today's world", "unlock", "game-changer", "dive in", "it's no secret", "in this post", "welcome back to my channel", "without further ado" …).

A score is a heuristic, not a prediction of views. A 90 that says nothing true about your topic will still lose to a 60 that does. Use the score to catch weak openers, vague claims and filler — then judge the hook as a reader would.
