What makes a TikTok caption work
Captions on TikTok sit under your video and now stretch to 4,000 characters in the app, far more than the short caps a lot of older advice still quotes (posts published through TikTok's API are capped at 2,200). That length is a trap, though: only the first line or two shows before the "more" cutoff, so the hook has to land immediately. The caption is also where TikTok reads your keywords and hashtags for search and the For You page, which means it does double duty as a hook for humans and a signal for the algorithm. Most people waste it on a flat description of what's already on screen.
TikTok caption tips
- Front-load the hook in the first sentence; everything after the "more" cutoff is invisible until someone taps to expand it.
- Add a few specific keywords people actually search, since TikTok now indexes caption text for the search tab, not just hashtags.
- Pose a question or leave a small gap to invite comments; TikTok lists interactions like comments among the signals it uses to recommend videos.
- Mixing broad and niche hashtags helps reach, but stuffing ten generic tags reads as spammy and rarely beats two relevant ones.

Latest questions readers ask us about this topic.
What's the character limit for a TikTok caption?
TikTok's in-app caption box takes up to 4,000 characters, while posts published through TikTok's API are capped at 2,200. Despite the room, only the first line or two shows in the feed before a "more" button, so the opening words carry almost all the weight.
Do hashtags count toward the TikTok caption limit?
Yes. Hashtags, spaces, emoji and mentions all count against the 4,000-character total. They share the same field as your caption text, so heavy hashtag use eats into the space your hook and keywords occupy.
Does the TikTok caption affect the algorithm?
It does. TikTok scans caption text and hashtags for keywords that feed search and For You recommendations. Captions that prompt comments or rewatches also send positive engagement signals, which matters more than caption length itself.
