Captions are the single most underrated lever on TikTok, Reels and Shorts. They're often treated as an accessibility afterthought, but they directly drive completion rate.
Position
Keep captions in the middle third of the frame, away from platform UI (likes, profile, hashtags). Anything in the bottom 15% on Reels gets covered by the caption text and CTAs.
Pace
Word-by-word or short phrase pacing outperforms full-sentence captions for high-energy content. For slower educational content, full sentences with key terms highlighted work better.
Contrast
High contrast wins: white text with a dark stroke or a semi-opaque background. Avoid pure-color text on photographic backgrounds — readability drops on any frame with similar tones.
Brand consistency
Pick one caption style per channel and stick with it. FeedReels exposes a caption style picker with accent color and preset templates so the channel keeps a recognizable look across every video.
