What makes a TikTok caption work
A TikTok caption can run up to 2,200 characters, but short wins. Only the first 150 or so show without a tap, so say the important part first. The caption is not the video, it sets the video up. Use it to add the bit of context the video cannot show, or to tease what is coming with a question or a ‘wait for it’ line that keeps people watching. Watch time is one of the biggest signals TikTok uses, so anything that holds attention helps. For hashtags, three to five is plenty: one broad tag for reach, one niche tag for your topic, and one topical or trend tag to ride what is popular now. The drafts here come with that mix built in.
Frequently asked questions
How long can a TikTok caption be?
You can write up to 2,200 characters, but keep it short. Only the first 150 or so show before someone has to tap, so say the important part right away.
How many hashtags should I add?
Three to five is the sweet spot. Mix one broad tag for reach, one niche tag that fits your topic, and one topical or trend tag that matches what is popular right now.
Do captions affect views?
Yes, indirectly. A caption that sets up the video or teases what is coming keeps people watching longer, and watch time is one of the biggest signals TikTok uses to show your video to more people.
What is a good hook for the caption?
A question or a "wait for it" line works well. It gives people a reason to keep watching to the end, which lifts your watch time.
