How to write TikTok captions that get your videos found

For a long time the caption was the least important thing on a TikTok. The video did the work, the hook got the first three seconds, and the caption was a place for a joke, an emoji, and a wall of hashtags. That changed when people started using TikTok the way they use a search engine: typing in a recipe, a product, a skincare routine, a city, and watching whatever comes up.

To answer those searches, TikTok has to work out what each video is about. It uses what is said out loud, what appears on screen, and the text you wrote in the caption. Of those three, the caption is the one you can write deliberately, in a minute, after the edit is done.

Say what the video is about in the first line

Only the opening of a caption shows over the video before it is cut off. That opening has to name the subject, in the words a viewer would use to describe it to a friend. Not a clever line about the subject: the subject.

• Weak: "this changed my mornings 😭". Nobody searches for that, and it tells TikTok nothing.
• Better: "5-minute high-protein overnight oats for busy mornings". It names the dish, the benefit, and the situation, all things a viewer might type.
• Weak: "POV: you finally found it". Found what?
• Better: "The quiet coffee shop in Lisbon with fast wifi and no laptop ban". Specific enough that the right person searching for it lands on your video.

A quick test: could someone who has not seen the video tell what it is about from the first line of the caption alone? If not, rewrite it.

Keep it to a sentence

TikTok lets you write a long caption, and there are niches where a mini blog post under the video works. For most videos, one clear sentence does the job better. The viewer is watching, not reading, and a single sentence gets the subject across before the cutoff without asking for their attention.

If you want to add context, put it after that first sentence, never before it. The recipe quantities, the product name, the location, and the settings you used are all useful additions. A paragraph of scene-setting before the subject is not.

What to stop putting in captions

1. 1Engagement bait. "Comment YES if you agree" and "Follow for part 2" read as spam to most viewers, and they spend the most valuable line of the caption on something that is not about the video.
2. 2Hashtag walls. Twenty hashtags push the actual sentence out of view and make the caption look like a template. Three to five relevant ones are plenty.
3. 3Inside jokes with no subject. A caption that only makes sense after watching gives search nothing to work with. Save the joke for the second sentence.
4. 4The same caption on every video. It teaches TikTok nothing about which video is which.

Where hashtags fit

Hashtags still help TikTok place a video, but they are a nudge rather than the mechanism. Put a small set at the end of the caption: a few that describe what the video specifically shows, and one or two broad ones for the category it belongs in. Write them in the same language as the rest of the caption, since that is the audience the video is for.

Make the caption and the hook do different jobs

The hook is the first line of the video. It opens a question for someone who is already watching. The caption is for someone who wants to know what they are watching, and for search. If the caption just repeats the hook, you have used your one piece of searchable text on a line that was designed to be vague. Let the hook tease and the caption explain.
