Video Hook: What the First 3 Seconds Should Say

A video hook is the opening line and picture of a short video, the first 3 seconds that decide whether a viewer keeps watching. For a business, it should name the viewer's problem or the result they want, show it on screen at the same moment and hint at what the rest of the video delivers.

• TikTok advises introducing your content proposition in the first 3 seconds for better recall and awareness (TikTok for Business, Creative best practices for performance ads).
• The same TikTok page says to put your hook within the first 6 seconds to increase engagement and watch time (TikTok for Business).
• YouTube's Shorts camera, which records Shorts up to 3 minutes long, has a Get feedback button that analyses a video's hook and pacing (YouTube Help, Get started creating YouTube Shorts).
• The W3C names title text at the beginning of a video as text whose information should also be in the audio or a description (updated 17 September 2024) (W3C WAI, Description of Visual Information).

What should a video hook say in the first 3 seconds?

It should speak to the viewer about their own situation, in one short line, before saying anything about your business. The viewer should know within that line who the video is for and why to stay.

The simplest test is whether a stranger scrolling past would recognise themselves in the line. "Leaking tap keeping you up at night?" passes, because anyone with a leaking tap hears their own problem. "Welcome to Kamau Plumbing" fails, because it asks the viewer to care about you before you have given them a reason. The hook is not the place for your name, your history or a greeting, since those can come later or sit in the caption.

Most working hooks fall into a handful of patterns. The table below shows six, with examples for hypothetical businesses. None of them is a formula that always works, so treat them as starting points to test against your own viewers.

Pattern	What it does	Example (hypothetical)
Problem question	Names a problem the viewer has right now	"Leaking tap and no plumber available until Monday?" for a plumber in Nairobi
Result first	Shows the finished result, then explains how	"This is the cake. Here is how it was made in one morning." for a bakery in Leeds
Mistake to avoid	Warns about a common error	"Three things people get wrong when booking a removal van." for a removals firm in Bristol
Direct promise	Says what the viewer will learn or get	"How to choose running shoes in 30 seconds." for a sports shop in Manchester
Call out the reader	Names the exact audience or place	"Getting married in Mombasa this year?" for a wedding florist
Behind the scenes	Opens a door the viewer cannot normally see	"Here is what our kitchen looks like at 5am." for a café in Cardiff

Look at the plumber's line again. It names a problem and a deadline in eight words, without mentioning the business at all. That is the job of the hook: the business earns its mention by showing it can solve the problem in the next few seconds.

What should the viewer see while the hook is said?

They should see the same thing the words describe, ideally already in motion. The picture and the line should make one point together, not two separate ones.

If the line is about a leaking tap, the first frame is the drip, not the van or the logo. If it is about a finished cake, the cake is in the frame from the very first moment. Starting mid action works because there is nothing to wait for: the viewer lands in the middle of something happening. Slow pans across a shop front or a logo that fades in use up the opening seconds without giving the viewer anything to recognise.

Put the hook as text on the screen too, in short words placed away from the edges where the app's buttons sit. The W3C guidance on describing visual information names title text at the beginning of a video as information that should also be available in the audio (W3C WAI). In plain terms, the text on screen and the spoken line should carry the same message. That way the hook works whether the viewer is watching, listening or both.

Why do so many business videos lose viewers at the start?

Because they open with the business rather than the viewer, and the first seconds pass before anything relevant happens.

TikTok's own guidance for ads is to introduce your content proposition within 3 seconds and to put the hook within the first 6 seconds (TikTok for Business). Many business videos spend that time on an intro card, a jingle or someone saying hello. On a fast feed, those seconds read as an advert warming up.

The fix is usually to cut, not to add. Watch your last video and find the first moment where something the viewer would care about appears on screen. Cut everything before it and see whether the video still makes sense, because the new opening is often a stronger hook than anything written from scratch.

When you write a full video script for business, the hook is one line of five, and it is the line to draft last. Once you know the promise, the scenes and the close, the hook simply has to point at the best of them. Writing it first tends to produce a clever line that the rest of the video does not deliver.

How do you write a hook that works without sound?

Make the first frame and the on-screen words carry the whole message, so the spoken line adds to it rather than being the only way to get it.

The W3C explains that captions provide content to people who are Deaf and others who cannot hear the audio, and help people who take in written information better than speech (W3C WAI, Captions/Subtitles). For a hook, this means the caption of the first line should appear at once, not after a delay. A spoken question with no text on screen asks a viewer without sound to guess what the video is about.

Keep the opening text short enough to read in the time it is on screen. TikTok recommends 5 to 10 words per second when using on-screen text (TikTok for Business), so a 3 second opening has room for a short line rather than a paragraph. Muting the video and watching only the first 3 seconds is a quick test. If you can tell who it is for and why to keep watching, the hook works without sound.

How do you test which hook works best?

Post the same video with different hooks and compare how many viewers stay past the opening. Change only the hook, so the result tells you something.

Write three hooks for one video using different patterns from the table, such as a problem question, a result first and a call out. Film or edit the opening three ways and keep everything after it the same. Post them on different days so one busy evening does not decide the result. Then compare how far viewers watched in each platform's analytics, paying most attention to how many left in the first few seconds.

YouTube's Get feedback button in the Shorts camera gives an analysis of a video's hook and pacing before you post (YouTube Help). That is useful as a second opinion, though your own viewers' behaviour is the real answer. Platforms do not publish a target for how many viewers should stay past the hook, and the number varies by topic and audience. Compare each video with your own earlier ones rather than with a figure from elsewhere.

Which hooks should a business avoid?

Avoid any hook the video does not deliver on, and any claim you could not show on your website.

A hook that promises "the secret plumbers never tell you" and then shows a price list breaks trust in the first ten seconds. The same goes for false urgency, such as "Last chance!" on an offer that runs all year. If a customer later checks the website and finds the offer ongoing, the hook has cost you credibility.

Be careful too with hooks that depend on a number. "Fixed in 20 minutes" is a strong opening only if it is true for most jobs and your website says the same. If the real answer is "it depends", a problem question is safer and still effective. The aim is a hook you would be happy for a customer to quote back to you on the phone.

Questions business owners ask about video hooks

Should I say my business name in the hook?

Usually not in the first line. Put the name on screen later, in the close and in the caption, where viewers who are interested will look for it. The exception is when your name is already well known locally, in which case it can act as the call out.

Can a hook be a question?

Yes, and a problem question is one of the most reliable patterns for a business. Make it a question the viewer would answer yes to, such as "Need a cake by Saturday?". Avoid questions so broad that everyone answers yes, because they do not tell anyone the video is for them.

How many words should a hook have?

As few as it takes to name the problem or result, often under ten. Read it aloud with a stopwatch: if it takes longer than 3 seconds, shorten it. Remember that the on-screen text version may need to be even shorter than the spoken line.

Can the AI Video Maker write hooks for me?

Yes. Every script it writes starts with a hook based on your AI Web Maker website, and in the studio you can ask for 3 new versions of any line, including the hook. Ideas and scripts cost nothing, and a finished video costs 38 credits.

Write three hooks for your next video

Take the next video you plan to post and write three hooks for it, each using a different pattern from the table above.

Read each one aloud, check it takes under 3 seconds and confirm that the first frame shows what the line describes. Pick one to post now and keep the other two for the next two weeks, so you can compare results. Note where viewers drop off in each, and keep the pattern that holds them longest.

If you want a head start, you can see three video ideas for your business with the AI Video Maker by typing your website on its page. Each idea comes with a full script and an opening hook drawn from what your website says. Read the hooks with the patterns above in mind, and adapt the one that sounds most like how you would greet a customer at the door.
