How to write a TikTok hook that earns the next three seconds

Your hook is the first thing you say. Not the thumbnail, not the caption, not the on-screen text: the words that leave your mouth in the first breath. A viewer decides in that moment whether your video is worth the next few seconds, and nothing else in the video gets a chance if they leave.

This guide is a method for writing that line. It comes from the problems we see most often when we score opening lines, so it is about what to cut and what to move forward, not about tricks.

What a hook actually has to do

A hook has one job: give the right viewer a reason to keep listening. It does that in three ways, and the strongest hooks do more than one at once.

It opens a question the viewer wants answered (curiosity). It is specific enough to be believed (a real detail, number or situation instead of "this changed everything"). And it puts the viewer's problem or stake ahead of the creator's story (why it matters to them, not who you are).

Those three are the signals Contextify's hook check scores: curiosity gap, specificity and viewer stakes. You do not need our tool to use them. Read your own opening line and ask which of the three it does.

Five patterns that work for most niches

None of these is magic, and none guarantees a result. They are reliable ways to put the reason to care in the first sentence.

The contradiction: say the thing the viewer believes is wrong. The specific result: name what happened, with a real detail. The problem first: start from the viewer's frustration instead of your solution. The open loop: promise an answer and make them wait for it. The direct question: ask the exact thing your viewer has typed into a search bar.

Whichever you pick, finish the sentence with something only your video can deliver. A hook that could open any video in your niche is not doing its job.

Instead of “Hey guys, welcome back to the channel.”
try “Your espresso tastes sour for one reason, and it is not the beans.”

Instead of “Today I want to talk about editing.”
try “I cut forty seconds from this video and nobody noticed. Here is what I removed.”

Instead of “This tip changed my life.”
try “The one setting I turned off that fixed my blurry footage.”

The openings viewers have learned to skip

Viewers have heard the greeting, the warm-up and the vague promise thousands of times, and they know what follows. That is why these openings cost you, even when the idea behind the video is good.

The greeting ("hey guys, welcome back") carries no information. The warm-up ("so today I wanted to talk about") spends the first seconds announcing a topic instead of earning attention. The vague promise ("you need to hear this") gives nobody a specific thing to be curious about. The credentials opener ("as a coach with ten years of experience") puts you before the viewer.

The fix is rarely a better idea. It is usually moving the sentence that makes someone stay from sentence three to sentence one.

A five-minute process for writing yours

First, write the video's payoff in one sentence: what does the viewer know or get by the end? Second, find the most surprising or specific part of that payoff. Third, make that the opening line, and cut everything that comes before it. Fourth, read it out loud once. If you would not keep listening after that sentence, change it.

Then write two alternatives using different patterns from the list above, and pick the one you can say naturally. A hook you cannot say in your own voice will sound written, and viewers hear that.

How to test a hook before you record

You can test a hook without filming anything. Paste the line into Contextify's TikTok hook analyzer and you get a 0 to 100 score, the three signals underneath it, and the exact phrase costing you the most. A membership adds a re-recordable rewrite.

The score is a judgment about your words, not a prediction of views. Treat it as a way to compare your own versions of the same line, then let your real retention graph in TikTok, Instagram or YouTube Studio tell you what actually happened.
