How to Write LinkedIn Hooks That Stop the Scroll

LinkedIn hooks are the first line or two of a post, the part a reader sees before the "see more" link. A hook that works makes a specific, true promise about what is underneath. It names a number, a decision or a moment, and the rest of the post pays it off.
TL;DR: Write the post first. Find its most specific sentence and move it to the top. Keep the opening line to about twelve words, and cut any line that asks for a comment. The Founder / Exec LinkedIn Authority System ($79) includes honest hook patterns and a post checker that scores a draft Ship, Tighten or Rework. The pillar guide is How to Build Authority on LinkedIn (as a Founder).
A hook is a promise
Compare two openings. "Some thoughts on leadership." And: "I cut our churn 30% in 90 days." The first asks for trust the reader has not given yet. The second tells the reader what they will learn and hands them a number to hold you to.
That is the whole job. A hook does not have to summarize your argument. It has to give one concrete reason to keep reading, and the reason has to be real. Our post on video hooks covers the same job in the first two seconds of a clip.
Three patterns that stay honest
The system's templates list three hook patterns. Each one is built from something that happened.
- A result and its mechanism. "We cut [metric] by [number]. Here's the one change that did it."
- A real tension. "Everyone says [X]. After [experience], I think the opposite."
- A concrete moment. "A customer said something last week that changed how we [do thing]."
Patterns are meant to be reused. The details inside them are not. A reader who sees the same frame with the same kind of claim three weeks running will start to read the template and skip the post.
Draft the post, then mine it
- Write the whole post. Ignore the opening line until the end.
- Find the sharpest sentence. Look for the one with a number, a named decision, or a cost in it. It is often in the third paragraph.
- Move it to the top. Trim it to stand alone, at about twelve words or fewer.
- Read only the first two lines. Would you click? If you hesitate, rewrite.
How the post checker scores a hook
The system ships a small script, postcheck.py, and the product page runs the same scoring in your browser. Every draft starts at 50 points. The rules are simple enough to put in a table.
| What the checker finds | Points |
|---|---|
| First line is 12 words or fewer | +10 |
| First line ends in a question mark or contains a number | +8 |
| A number anywhere in the post (a bare year or list numbering does not count) | +8 |
| A first-person word such as I, my, we or our | +8 |
| Each listed engagement-bait phrase | -25, up to -50 |
| Each listed LinkedIn-slop phrase | -12, up to -36 |
| More than five hashtags | -10 |
| More than three all-caps words | -5 |
A score of 70 or more returns Ship, 45 to 69 returns Tighten, and below 45 returns Rework. A draft in which the checker finds a listed bait phrase cannot return Ship at any score. The highest possible score is 84, which is 50 plus 10 plus 8 plus 8 plus 8. The churn line above, with a short body, scores exactly that. "Some thoughts on leadership" with two flat sentences under it scores 60, Tighten.
Where the score and your judgment part ways
The checker likes numbers and questions, and that creates a real tension with honest writing. Take the second pattern above, the plain statement of disagreement. Give it a short first line and a first-person voice, and leave out any digit. It scores 50 plus 10 plus 8, which is 68. Tighten, two points short.
Adding "in 2026" to the body does not move it. The checker does not count a bare year or list numbering as a number, so the draft stays at 68. A real figure in the body, such as a count or a timeframe, adds 8 points and ships it at 76.
So treat the verdict as a prompt to look again. The checker counts characters and matches phrases from an editable list. Beyond skipping a bare year and list numbering, it cannot tell a real number from a decorative one, it cannot tell whether the post pays off the hook, and it only catches bait phrases written the way its list spells them. Whether a quiet, honest opening should be bent toward a number to clear 70 is your call. We would leave it at 68.
What to keep out of the first line
The templates name the openings to avoid: "the result will shock you," "comment YES below," "agree?" and announcements that are all flourish. Each one borrows attention the post cannot repay. The reader feels tricked at line three, and remembers who did it.
We will not give you a percentage for how much a good hook lifts reach. LinkedIn does not publish how its feed ranks posts, and a number borrowed from someone else's account would tell you nothing about yours. A hook that is the truest sharp sentence in your post is one you can still stand behind when a prospect quotes it back to you on a call.
Check the hook before you publish
The Founder / Exec LinkedIn Authority System includes honest hook patterns, four post frameworks, and postcheck.py, which scores a draft out of 100 and returns Ship, Tighten or Rework with the reasons listed. The phrase lists and thresholds sit in a settings file you can edit. It is a heuristic and cannot promise reach.

The Anti-Slop Content System ($79) goes past the first line: a heuristic slop scanner and the SPARK scorecard grade the whole draft Publish, Revise or Rework. It is a quality guardrail and does not detect AI. The Brand Voice Engine ($59) turns your voice into a Voice Spec and checks drafts against it with a 100-point QA Checker. Once a post lands, the AEO-Aware Content Repurposing System ($79) has templates for adapting it to other channels, with its own Ship, Tighten or Rework readiness scorer.
More in this guide
What makes a LinkedIn hook work?
A specific, true promise in the first line or two. Name a number, a decision or a moment, and make sure the rest of the post delivers on it.
How long should a LinkedIn hook be?
One or two short lines. The post checker in the LinkedIn Authority System rewards an opening line of 12 words or fewer.
Should I write the hook before or after the post?
After. Write the full post, find the most specific sentence in it, and move that sentence to the top. It is easier than inventing an opening cold.
Is clickbait a good hook strategy on LinkedIn?
No. A dramatic opening that the post does not pay off makes the reader feel tricked, and it costs you the trust a hook is meant to earn.
Does a strong hook guarantee more reach?
No. LinkedIn does not publish how its feed ranks posts, and no technique guarantees reach. A good hook gives a reader an honest reason to keep reading.
Can a post with a good score still be a bad post?
Yes. The checker counts things like line length, numbers and listed phrases. It cannot tell whether the post is true or whether it pays off the hook. Use the verdict as a prompt to reread.
