How to Write Hooks for Social Media Posts
Seven Hook Types, Where the Hook Lives on Each Platform, and How to Keep the Promise
Short answer
A social media hook is the opening line, frame or slide that decides whether someone keeps reading. Strong hooks make one specific, true promise about the reader’s situation in plain words. Write the post first, then pull its most surprising true sentence to the front, and make sure the next lines pay it off.
1. What is a hook in a social media post?
The hook is whatever a person sees before deciding to keep going: the opening line of a text post, the first frame of a video, the cover slide of a carousel. It is a promise, and the rest of the post is the delivery.
- Hook
- The opening element of a social post, such as its first line, frame or slide, whose job is to make a specific promise that earns the reader’s next few seconds of attention.
- Also known as: Opening line, Scroll stopper
Most feeds show a post truncated: a few lines of text, a cover image, the opening moments of a video. That preview is all most people ever see. A post with a strong body and a weak opening is, in practice, a weak post, because the body is only read by people the opening already convinced.
A hook is not a trick. The best ones are the most interesting true sentence in the post, moved to the front. If the post has no interesting true sentence, the problem is the post, not the hook.
2. Where does the hook sit on each platform?
Wherever the preview ends. On LinkedIn it is the lines before "see more", on Instagram the image plus the first caption line, on carousels the first slide, and on short video the opening seconds and on-screen text.
| Platform and format | Where the hook is | What it has to do |
|---|---|---|
| LinkedIn text post | The first lines before "see more" | Make the claim fully, so the post works even if nobody expands it |
| X post or thread | The first post, and its first words | Carry a complete, useful point plus the promise of more |
| Instagram feed post | The image, then the first caption line | Add something the image cannot show |
| Carousel or document post | The cover slide | Promise what swiping delivers, readable in a glance |
| Reels, TikTok, YouTube Shorts | The opening seconds and any on-screen text | Show or say the payoff up front, and make it work with the sound off |
| Facebook post | The first line and the image together | Work as one unit, as neither is read on its own |
3. What types of hooks work, with examples?
Seven types cover most good hooks: a specific number, a named situation, a contrarian claim, a common mistake, a question customers ask, a before and after, and a bounded promise. Each has a way it backfires.
| Hook type | Example | Backfires when |
|---|---|---|
| Specific number | "Our customers take their first online booking in [your measured time] on average." | The number is not true, not current, or cannot be sourced |
| Named situation | "If your clients pay late every single month, it is usually the invoice, not the client." | The situation is so broad it names nobody |
| Contrarian claim | "Posting every day is making your bakery’s account worse." | You do not actually hold the view, or cannot defend it |
| Common mistake | "The most common bookkeeping mistake we fix for restaurants is not a missing receipt." | It shames the reader instead of helping them |
| Question customers ask | "Can you really brew good coffee with a French press? Yes, with one change." | Nobody actually asks it |
| Before and after | "Friday afternoons used to be invoice chasing. Now they are not." | The after is vague or the before is exaggerated |
| Bounded promise | "Three checks before you sign a studio lease." | The post delivers fewer or weaker items than promised |
4. How do I write a hook for a post?
Write the whole post first, find its most surprising true sentence, then draft five versions of that sentence as an opening. Pick the most specific one and cut every word of wind-up before it.
Writing the hook last is the single change that helps most. The procedure takes ten minutes per post.
- Write the post before the hook. Draft the body so you know exactly what the post delivers. A hook written first makes a promise the body then has to bend to fit, which is how posts end up overpromising.
- Find the most surprising true sentence. Read the draft and mark the line a reader is least likely to expect: a number, a reversal, a specific consequence. That line is the raw material for the hook.
- Draft five openings from it. Try it as a number, a situation, a mistake, a question and a promise. Five versions take a few minutes and almost always produce one far better than the first.
- Cut the wind-up. Delete "Here is the thing", "Let’s talk about", greetings and any sentence about how you feel. The first words should carry the claim.
- Check the next two lines pay it off. A reader who expands the post should get the first piece of the promised value immediately. If the payoff is buried at the end, move it up.
5. How do I avoid hooks that feel like clickbait?
Only promise what the post delivers, and deliver it fast. Clickbait is a hook the body cannot pay off, and followers learn to discount accounts that do it, even when a later post is good.
The damage from an overpromising hook is not one disappointed reader, it is a pattern. After a few posts that open big and deliver little, followers stop trusting the openings, which means the account has to shout louder every time to get the same attention.
Three checks before publishing:
- Could the claim in the hook be read aloud to a customer without embarrassment?
- Does the post deliver the promised number of items, at the promised level of usefulness?
- Would the hook still be accurate if a competitor quoted it back to you?
6. How can I test which hooks work for my account?
Keep a hook log: the hook type, the post, and how it did against your account’s usual range. Small accounts cannot run clean tests, so look for patterns across many posts rather than winners from one.
For most small accounts a true A/B test of hooks is not readable, because the numbers per post are too small to separate luck from effect. What works instead is recording every hook’s type next to the post’s result and looking at the pattern after a few months.
Compare each post against the median of your own recent posts on the same platform, not against the account’s best post. If one hook type sits above your median again and again, write more of it. If a type has never beaten the median after several tries, retire it for that platform.
The creative testing guide covers why small samples mislead, and the same logic applies to hooks: an unreadable result is no answer, not a weak answer.
7. Where do good hook ideas come from?
From the questions customers actually ask, the objections sales hears, and the posts in your market that already get replies. Hooks built on real language beat hooks built on formulas.
Comments, support tickets and sales calls are full of hook material, because they contain the exact words customers use for their problems. A question asked three times this month is a hook waiting to be written.
Competitor posts are useful here too. The posts that get unusual engagement in your market show which situations and claims your audience responds to. Oppira Intel tracks competitors’ posts across Facebook, Instagram, X and LinkedIn and surfaces their standout content, and Studio drafts posts in your brand voice from your Playbook, so the hook work starts from real market signals instead of a blank page.
Key Takeaways
The hook is what most people see
Feeds show a preview. A post with a strong body and weak opening performs like a weak post.
Know where the preview ends
Lines before "see more", the first caption line, the cover slide, the opening seconds. Write for that boundary.
Write the hook last
Draft the post, find its most surprising true sentence, then write five openings from it.
Seven types cover most good hooks
Number, situation, contrarian claim, mistake, customer question, before and after, bounded promise.
Only promise what you deliver
Overpromising hooks train followers to discount every opening you write, including the honest ones.
Log hooks, do not A/B them
Small accounts cannot read single tests. Record hook type against your median and look for patterns.
