How to Write Hooks That Stop the Scroll on Each Platform

Most posts are not skipped because they are bad. They are skipped because the first thing people saw gave them no reason to stay. That first thing is the hook, and it is smaller than most people think: a line of text, a cover slide, a subject line, the first second of a video. It decides whether anything else you wrote gets read.

A good hook is not a trick, either. It is a promise the rest of the post keeps. Clickbait makes a promise and breaks it; a hook makes one and delivers. That difference is what people remember about you the next time your name appears in their feed.

What a hook has to do

Whatever the platform, the opening has three jobs, and it has to do them in very little space:

• Tell people it is for them. Name the situation, the role or the problem they recognise: “If you invoice clients yourself…”
• Make a specific promise. Not “some thoughts on pricing” but “why we stopped offering a free tier.”
• Leave a reason to continue. A tension, a gap or a surprise that the next line resolves.

If an opening does only one of these, it usually reads as vague. If it does all three, it rarely needs exclamation marks.

Five hook shapes that work almost anywhere

• The specific claim. State your point plainly and a little more firmly than feels comfortable: “Your onboarding email is too long, and the fix is cutting the first paragraph.”
• The honest mistake. People lean in when you admit something: “We spent three months building a feature nobody asked for. Here is what we check now.”
• The question they already ask. Use the exact words customers use, not your internal language: “Is dark roast stronger?”
• The contrast. Before and after, expected and actual, what people think and what happens: “Everyone tells you to post daily. We got further posting twice a week.”
• The number you can stand behind. A real figure from your own work is a strong hook. A borrowed one is a liability.

Platform by platform

Platforms change their layouts from time to time, so treat the specifics below as working guidance and look at a few real posts on your own phone before you rely on them.

LinkedIn

Only the first two or three lines show before see more, and on a phone that is not much. Put the promise in the first line, then a line break, so the opening reads as a complete thought on its own. Skip the warm-up: “I've been thinking a lot lately about…” spends your only visible line on nothing. Compare “Excited to share some reflections on hiring” with “We stopped asking for cover letters. Applications got better.”

X

On X the whole post is the hook. With 280 characters on a standard account, there is no room for a run-up: one idea, said cleanly, usually beats a compressed paragraph. If you are writing a thread, the first post has to stand alone and say what the thread will give people — and the thread has to deliver it.

Instagram

The image or the carousel cover is the hook; the caption supports it. A cover slide should state the promise in a few large words people can read at a glance — “Light, medium, dark: what actually changes” — not a logo and a mood. Only the start of the caption shows before more, so its first sentence should add something the image did not say.

TikTok, Reels and Shorts

In short video the hook is the first second, and it works on three channels at once: what people see, what they hear and the text on screen. Start in the middle of the action rather than with a greeting, put the promise on screen as text for people watching without sound, and say it out loud in the same breath. “This is the grind setting most people get wrong”, said while you turn the dial, does all three.

YouTube

For longer videos the title and thumbnail are the hook, and the opening moments are where you prove they were honest. Confirm the promise quickly and show where the video is going; a long intro before the thing the title promised is where people leave.

Reddit

Reddit readers are allergic to marketing. The title is the hook, and it works best as the real question or the useful claim, written the way a member of that community would write it. Open the body with the answer or the substance, not with who you are, and read the community's rules before you post anything that mentions a business.

Email newsletters

The subject line and the preview text are one hook in two parts. The subject names the topic; the preview adds the twist or the reason to open now. If you don't write the preview text, the inbox shows whatever your email starts with — often “View in browser” or a greeting.

How to write ten hooks in fifteen minutes

1. 1Write the point in one plain sentenceIf you can't, the problem is the idea, not the hook. Fix that first.
2. 2Rewrite it in each of the five shapesClaim, mistake, question, contrast, number. Two versions of each gives you ten.
3. 3Cut the warm-up from every oneDelete the first few words and see if it still makes sense. It usually reads better.
4. 4Read them out loudAnything you wouldn't say to a person across a table goes.
5. 5Check the post keeps the promisePick the hook the rest of the post actually delivers on, not the most dramatic one.

Openings to retire

Some openings are so common that readers skip them on sight. They are not wrong; they are invisible.

• “In today's fast-paced world…”
• “I'm thrilled to announce…” (say what it is instead)
• “Unpopular opinion:” followed by a popular opinion
• “Let that sink in.”
• “You won't believe what happened next.”
• “Here's the thing.” as a first line

Once you have a hook you like, the next problem is using the same idea again without sounding like a rerun — that is what turning one idea into eight pieces is about. And if you would like a first draft to react to, Postclo writes the post from your project, opens it the way a scrolling reader pays attention, and never invents a number or a story. You review every line before anything goes out.
