The opening line decides everything

Why LinkedIn hooks decide everything

LinkedIn collapses every post after roughly the first two lines and shows a 'see more' link in its place. On mobile, that cutoff arrives even sooner. Nobody has to click through, and most people do not.

That makes your hook the entire post for most of your audience, not an introduction to it. If it does not do its job alone, the argument, the story or the offer underneath it never gets read, however good it is.

This is also why warm-up sentences cost more than they seem to. Lines like 'I have been thinking a lot about...' or 'As a founder, one thing I have learned...' spend the one sentence you are guaranteed to be read on nothing. By the time the real point arrives, the reader has already moved on.

Newsrooms solved this long before feeds existed. The lead paragraph carries the story precisely because most readers never reach the second one.

Five hook patterns that earn the second line

These five patterns show up again and again in posts that get read past the fold. None of them are tricks. Each one gives the reader a specific reason to click 'see more', instead of asking them to trust that something good is coming.

• The flat claim: state your actual opinion in the first line, with no lead-in.
• The specific number: replace a vague claim with one exact figure from your own experience.
• The second-person question: ask something the reader has to answer about their own situation.
• The mid-scene opening: start inside a moment, not before it.
• The contradiction: say what people usually believe, then say why it is wrong.

1. The flat claim

Before: 'I wanted to share some thoughts on hiring your first salesperson as a technical founder.'

After: 'Your first salesperson should not be your best closer. They should be the person who asks the most annoying questions.'

The before line describes the post. The after line is the post's actual argument, moved to the front. A reader who agrees, disagrees, or wants to know why, clicks either way.

2. The specific number

Before: 'We made a lot of changes to our onboarding flow recently, and the results were encouraging.'

After: 'We cut our onboarding from nine steps to three. Here is what we removed, and why two of the six we cut should never have existed.'

'A lot of changes' and 'encouraging results' are vague enough to skip past. A number is concrete enough to make someone want the story behind it.

3. The second-person question

Before: 'Pricing is one of the hardest decisions a SaaS founder has to make.'

After: 'Have you priced your product by copying a competitor's page and rounding to a number that felt safe?'

The first version states a general truth nobody argues with, which is exactly why it is easy to scroll past. The second version asks the reader to answer for themselves, and most people cannot resist checking.

4. The mid-scene opening

Before: 'Yesterday I had a difficult conversation with a customer about churn.'

After: 'We are cancelling at the end of the month,' the email said. I read it twice before I understood why.

The before line summarises what happened. The after line drops the reader into the moment itself, before they know how it ends.

5. The contradiction

Before: 'Consistency is important when building a personal brand on LinkedIn.'

After: 'Posting every day is the fastest way to run out of things worth saying.'

The first line agrees with what everyone already believes, so there is nothing left to discover. The second line sets up a disagreement the reader wants resolved.

Common mistakes that undo a good hook

A hook can follow one of these patterns and still fail, if it makes one of these errors.

• Answering your own question in the same sentence, which removes the reason to click.
• Stacking two ideas into one hook, so neither lands.
• Opening with a fact that is only interesting to you, not to the reader.
• Burying the actual claim in a second line, after a throat-clearing first line.
• Writing a question with an obvious answer, which reads as filler rather than curiosity.

If the hooks above are fine but the real problem is not knowing what to write about in the first place, that is a separate question, and our guide to LinkedIn post ideas for founders is a reasonable place to start. A hook only works if there is a real post behind it.

How to test a hook before you publish

You do not need software to check a hook. Two minutes and a phone screen tell you almost everything.

Open the post in the LinkedIn mobile app, the way most of your audience will see it, and read only what appears before 'see more'. If those lines alone do not make sense as a complete thought, or do not make you want to know what comes next, rewrite them before touching anything else in the post.

Then read the hook out loud, on its own, to someone who has not seen the rest of the post. If they ask 'and then what happened' or 'wait, why', the hook works. If they nod and wait for you to keep talking, it does not.

If testing and rewriting several hooks a week is not something your week has room for, that is a fair amount of what our retainer is built to take off your plate. The strategy and the drafts happen elsewhere. Only the approval reaches your phone. The full process is in how Cubeduck works.
