How to write scroll-stopping social media hooks for every platform
The first line of a post decides whether the second one gets read. This guide breaks down how to write social media hooks around three strategic angles — Conversion, Engagement, and Authority — and how each angle changes across the platforms people actually post to.
The three hook angles
Every strong hook does one job well. Trying to do all three at once dilutes the pull. Pick the angle that matches the outcome you want from the post.
- Conversion: promise a specific result and hint at the shortcut. Example: "The 3-line bio that tripled my booked calls this quarter."
- Engagement: open a loop, take a side, or ask a sharp question. Example: "Unpopular opinion: most 'growth hacks' are just good copywriting in disguise."
- Authority: lead with a data point, framework, or non-obvious observation. Example: "After analysing 500 launch posts, the top performers all shared one structural pattern."
Platform-by-platform hook patterns
The first line is truncated at ~125 characters. Front-load the promise or the tension — the "more" button only gets clicked when the opener earns it. Conversion hooks work well with a specific number; engagement hooks lean on relatable frustration; authority hooks open with a credential or count.
TikTok
You have roughly two seconds. Say the payoff out loud in the first frame and mirror it in the on-screen caption. Pattern-interrupt openers ("Stop scrolling if you sell on Instagram") beat clever intros. Save the setup for after the hook lands.
LinkedIn rewards a full first line and a hard line break before the "see more" cut. Lead with a concrete before/after, a contrarian claim about your industry, or a single number that reframes a common assumption. Avoid emojis in the hook — they suppress reach in most feeds.
X
The hook is the post. Compress to one strong claim, one number, or one question. For threads, the first tweet has to be able to stand alone as a shareable idea — nobody expands a thread whose opener needs the second tweet to make sense.
YouTube Shorts
Title-style hooks win. Curiosity + specificity: "The pricing page mistake costing you 30% of sign-ups." Say the same words on camera in the first second — the algorithm reads both the on-screen title and audio for retention signals.
Threads, Facebook, Pinterest
Threads rewards casual, in-the-moment hooks ("Just realised..."). Facebook still rewards conversational, community-oriented openers. Pinterest reads the first line as search-adjacent copy — put the benefit and keyword in the opening sentence.
A hook checklist you can steal
- Is the outcome obvious in the first line?
- Does it match one angle — Conversion, Engagement, or Authority — cleanly?
- Does it fit the platform's truncation and native rhythm?
- Would it still work if you deleted every emoji and hashtag?
- Can a stranger read the first sentence and tell what the rest is about?
Or skip the blank page
