How to Write Viral Video Hooks (With Examples)

The first 2 seconds of your video determine whether someone keeps watching or scrolls away. On TikTok, YouTube Shorts, and Instagram Reels, the algorithm measures completion rate — and completion rate starts in the first second.

A great hook doesn't happen by accident. Every top short-form creator has a hook formula — a repeatable pattern they use to open clips in a way that makes scrolling feel impossible. This guide breaks down the five patterns that work, with examples, and shows you how to apply them to your content.

What Makes a Hook Work

A hook has one job: create tension. Tension is the feeling that something important is about to happen — a revelation, a payoff, a contradiction. When a viewer feels that tension in the first 2 seconds, their brain won't let them scroll away until it's resolved.

The five hook patterns below all create tension in different ways. The best creators aren't original — they're systematic. They know which pattern fits their content type and they use it every time.

The 5 Hook Patterns That Stop the Scroll

1. The Curiosity Gap Hook

The curiosity gap hook teases a piece of information without revealing it — forcing the viewer to keep watching to get the answer.

Formula: "Most people don't know [X] about [topic]..." or "Here's what actually happens when you [action]..."

Examples:

• "Most YouTubers don't know this is suppressing their Shorts reach."
• "Here's what actually happens to your TikTok view count after 24 hours."
• "Nobody talks about this, but it completely changed my content strategy."

This hook works because the brain experiences discomfort when it senses incomplete information. It's nearly impossible to scroll past an unanswered question that feels relevant to you.

2. The Bold Claim Hook

The bold claim hook makes a statement that's surprising, counterintuitive, or more confident than the viewer expected. It challenges an assumption.

Formula: "Stop doing [common thing]. Here's why it's killing your [result]." or "[Widely believed thing] is wrong."

Examples:

• "Posting more Shorts is actually hurting your channel growth. Here's what to do instead."
• "The best time to post on TikTok doesn't exist."
• "I stopped optimizing for views and doubled my revenue."

The bold claim hook works because humans are wired to notice contradiction. When something challenges what they believed to be true, attention spikes.

3. The How-To Promise Hook

The simplest hook pattern: tell the viewer exactly what they're about to learn, with a specific and achievable outcome.

Formula: "Here's how to [specific result] in [time frame / number of steps]."

Examples:

• "How to turn one YouTube video into a week of Shorts in 10 minutes."
• "Three things I do before every podcast recording that doubled my clip performance."
• "Here's the exact caption style that increased my Reels completion rate by 40%."

This hook works when the promise is specific. "Get more views" is weak. "Add this one element to your hook and watch completion rate go up" is specific — and specific is watchable.

4. The Story Arc Hook

The story arc hook opens with the end of a story, then implies the beginning will be revealed. It's the "before we get into that, here's what happened" pattern.

Formula: "In [short time], I went from [before] to [after]. Here's how."

Examples:

• "In 90 days, I went from 800 to 24,000 subscribers. Here's exactly what changed."
• "I tried posting every day for a month. My account almost died. Here's what I learned."
• "Six months ago I was about to delete my channel. This week I hit 1 million views."

The story arc hook works because humans are programmed for narrative completion. When you present a dramatic before/after without explaining how, the viewer needs to know the answer.

5. The Pattern Interrupt Hook

The pattern interrupt uses a visual or audio cue that's unexpected enough to stop the unconscious scrolling reflex. It works by breaking the visual rhythm the viewer was expecting in their feed.

Examples:

• Starting your video mid-sentence, already in action, instead of a traditional greeting.
• Opening with a strong sound effect, unusual visual, or unexpected jump cut.
• Starting with a question directed at the viewer: "Have you ever noticed that...?"

This is harder to script and more dependent on delivery and editing — but in combination with any of the other four hooks, a pattern interrupt in the first frame dramatically increases the chance that someone pauses their scroll.

How to Write a Hook Before You Film

The biggest mistake creators make: filming first and finding the hook later. Top performers write 3 hook options before filming a single second. Here's the process:

1. Identify the core value: What's the one thing someone should know or feel after watching this clip?
2. Pick your hook pattern: Which of the five patterns fits this content type? (Curiosity gap for insights, how-to for tactics, story arc for results.)
3. Write 3 variations: Write three versions of the hook — one bold, one specific, one conversational. You'll know which one is strongest when you read them aloud.
4. Test the tension: Read your hook out loud and ask: would a stranger feel compelled to hear what comes next? If you're not sure, it needs more specificity or more audacity.

Applying Hooks to Repurposed Content

If you're repurposing long-form content (podcasts, interviews, webinars), the hook challenge is different: you need to find the hook inside footage you've already recorded, not write it before filming.

This is where AI clipping tools like Short.now's AI Hook Generator become valuable. The AI analyzes your video and scores moments by hook strength — identifying clips that open with curiosity gaps, bold claims, or strong story setups automatically. For creators repurposing 60-minute episodes into Shorts, this saves hours of footage review per video.

When reviewing AI-suggested clips, use the five patterns above as your editorial filter. Ask: does this clip open with any of the five hook types? If yes — and if the hook is strong — it's worth posting. If the best available clip doesn't have a strong natural hook, you can add one: record a short 2-3 second intro piece that sets up the clip with a curiosity gap or bold claim, then cut to the original footage.

Hook Performance by Platform

TikTok

TikTok's audience is the most hook-sensitive. The algorithm's test-and-distribute model means bad hooks get suppressed immediately — and great ones get pushed to millions. Bold claims and curiosity gaps perform best. Conversational hooks ("you've probably experienced this...") also work well because TikTok feels like a one-on-one conversation.

YouTube Shorts

Shorts viewers spend more time on YouTube broadly and are often willing to watch longer content. How-to promises and curiosity gaps work well — especially when they hint at value that could also exist in a longer video on your channel. Shorts hooks that drive long-form channel exploration are uniquely valuable because they serve a discovery purpose the other platforms can't.

Instagram Reels

Reels viewers respond well to story arc hooks and transformation statements — especially anything visual. "Before/after" is native language on Instagram. Hooks that reference a visible change or result tend to perform better than pure information hooks.
