How to create a LinkedIn hook with this generator

  1. Enter your topic

    Use a few words, like “cold email” or “hiring”. Add who the post is for, in the plural, and a real result if you have one.

  2. Pick a hook that is true for your post

    Each hook is labeled with its pattern: mistake, story, list, question, proof and more. Choose the one that matches what your post actually says.

  3. Fill in the brackets and copy

    Replace anything in [brackets] with your real detail, then copy the hook into your post. Use “Check this hook” to score it first.

What makes a LinkedIn hook work

It is specific. “I almost fired the only engineer who understood our system” beats “Leadership is hard”, because it names a real moment.

It opens a loop. A question, a contrast or a line that ends in a colon makes the reader want the next line.

It is short. About 130 characters across the first two lines usually keeps the whole hook above “see more”.

It is true. A hook promises something. If the post does not deliver it, readers notice and stop trusting your next one.

LinkedIn hook templates and examples by pattern

Mistake: “The biggest cold email mistake I see early-stage founders make:”

Story: “I got hiring wrong for two years. Here is what I changed.”

List: “3 pricing lessons I wish I had learned sooner:”

Proof: “How I booked 14 demos in 30 days, step by step:” Use this one only with a result you can show.

Frequently asked questions

What is a hook on LinkedIn?
The hook is the first line or two of your post. In the feed, LinkedIn shows only the start of a post before a “see more” link, so those lines decide whether someone stops scrolling and opens the rest.
How does this LinkedIn hook generator work?
It fills common hook patterns with your topic, your audience and, if you add one, a real result. It does not use AI and does not make anything up: details only you know, like how long something took, stay in [brackets] for you to fill in.
Is this a hook writer or a hook generator?
Both names describe the same job: giving you opening lines to start a post. This tool writes 10 or more hooks for your topic in different patterns, so you can pick the one that fits the story you want to tell.
How long should a LinkedIn hook be?
Aim for about 130 characters across the first two lines so the whole hook shows before “see more” on most screens. A short first line, under about 70 characters, is easier to take in at a glance.
Which hook pattern works best?
There is no single best pattern. Proof hooks work when you have a real, specific result. Mistake and contrarian hooks work when you disagree with common advice. Story hooks work when you can name a real moment. Pick the one that is true for your post.
Can I check a hook I already wrote?
Yes. Use the LinkedIn hook checker to score your first lines for length, clichés, concrete details and clutter. Every hook generated here has a “Check this hook” link.
Is this LinkedIn hook generator free?
Yes. It is free with no signup, and the hooks are built in your browser. What you type is never sent to WriteHero.
