On TikTok and Instagram Reels, the first one to two seconds decide whether anyone sees the rest of your video. The algorithm watches how many viewers stay past the opening, and if they swipe away, the video stops being shown. That opening is the hook, and it is the single biggest lever in short-form marketing.
Below are 20 hook templates we use as starting points, grouped by the psychology behind them, with example lines for three kinds of businesses. The examples are illustrative: adapt the words to your product and your customers' language.
1. Problem hooks: name the pain
1. "If you [specific frustration], watch this."
- App: "If you open your budgeting app and immediately close it again, watch this."
- SaaS: "If your team still updates the sprint board by hand on Fridays, watch this."
- E-commerce: "If your water bottle smells weird after a week, watch this."
2. "Stop [common mistake]."
- "Stop paying for five subscriptions that do the same thing."
- "Stop sending invoices as Word documents."
3. "Nobody tells you this about [topic]."
- "Nobody tells you this about learning a language after 30."
4. "I wasted [time/money] on [thing] so you don't have to."
- "I wasted $3,000 on Google Ads for my app so you don't have to."
2. Curiosity hooks: open a loop
5. "I didn't expect [result] when I tried [thing]."
- "I didn't expect my sleep score to change when I stopped scrolling at 11pm."
6. "Here's what happened after 30 days of [action]."
- "Here's what happened after 30 days of using an AI meal planner."
7. "The [category] trick that [authority group] doesn't talk about."
- "The spreadsheet trick accountants don't talk about."
8. "Wait for the end." (Use only if the ending is genuinely worth it.)
3. Proof hooks: show, don't tell
9. Before/after in the first frame.
- A messy desk becomes a clean one; a chaotic calendar becomes a planned week; dull skin becomes glowing.
10. "[Number] people [result] with this." (Only with real numbers.)
- "4,000 freelancers sent their invoices with this last month."
11. Screen recording with a result on screen.
- Open on the dashboard that shows the outcome, then rewind to how you got there.
12. "I tested [product] vs [competitor] so you don't have to."
4. Identity hooks: call out the viewer
13. "POV: you're a [role] and [situation]."
- "POV: you're a solo founder and it's 2am and Stripe just failed."
14. "This is for the [specific group] who [behaviour]."
- "This is for the nurses who meal prep on Sunday nights."
15. "Things only [group] understand."
- "Things only Shopify store owners understand on Black Friday."
16. "If you're [age/role] and still [behaviour], this is your sign."
5. Story and controversy hooks
17. "My boss/client/mum said [quote], so I [action]."
- "My client said the report would take a week. I did it in four minutes."
18. "Unpopular opinion: [contrarian take]."
- "Unpopular opinion: you don't need a marketing agency for your first 100 users." (This works best when you can back it up.)
19. "The day I almost [failure]."
- "The day I almost shut down my store, one TikTok changed everything."
20. Reply to a comment.
- Use TikTok's "reply with video" feature on a real question: "How do you track inventory with just two people?" It shows social proof and answers a real objection at the same time.
How to write a hook that works
- Say it, show it and write it. The first frame should combine spoken words, an on-screen caption and a visual that matches. Many people watch with the sound off.
- Be specific. "Save time" is weak. "Stop spending Friday afternoons on timesheets" is strong.
- Start mid-action. Cut the "Hi guys, today I want to...". Start with the most interesting moment.
- Match the promise. If the hook promises a trick, deliver it within 15 seconds. Misleading hooks hurt watch time and trust.
- Use the customer's words. Pull phrases from reviews, Reddit threads and support emails.
A weekly testing system
We test hooks the way performance marketers test ads:
- Monday: brainstorm 10 hooks using the templates above and your customers' language.
- Tuesday–Thursday: film variants. Same body, different first three seconds. One creator can film 5 hooks in an hour.
- Friday: review the numbers. For each video check the 2-second and 3-second retention, average watch time, shares and saves, and link clicks or sign-ups.
- Keep the top 2 hooks, drop the rest, and write new variations of the winners for next week.
After 4–6 weeks you will know which angles work for your audience. That is far more valuable than any single viral video.
Key takeaways: the first two seconds decide everything; problem, curiosity, proof, identity and story hooks each work for different products; be specific and use the customer's language; test 10 hooks a week and keep only the winners.
The CAC maths: is creator content working? (illustrative)
Views are not the goal. Here is how to compare creator content with paid ads, using example numbers for a subscription app:
- Paid social: $5,000 spend → 1,250 installs at $4 per install → 6% convert to paid → 75 subscribers → CAC about $67.
- Micro-creator wave: $5,000 across 8 creators → 2,100 installs (including organic views in the following weeks) → 7% convert to paid → 147 subscribers → CAC about $34.
In this example, creator content brought in subscribers at about half the cost. Your numbers will differ, but the method is the same: track installs, sign-ups or orders per creator, then compare cost per paying customer, not cost per view. If the creator CAC is lower, boost the winning videos as ads to scale them further.
Mistakes to avoid
- Copying a viral hook word for word. Use the structure, not the exact line.
- Judging a hook on one video. Test each angle at least two or three times before deciding.
- Clickbait that doesn't pay off. Viewers punish broken promises by swiping away, and the algorithm notices.
- Forgetting the call-to-action. End with one clear next step: link in bio, search the app name, comment a keyword.
How SENERVerse applies this
Every SENERVerse campaign tests 10+ creative hooks a week across our creator network, then shifts budget to the hooks that bring installs, sign-ups and orders. You get a weekly report with retention, cost per customer and the next hooks to test.
