Why Subtitle Structure Matters
Subtitle text inside carousels helps both readers and image-recognition systems understand the topic more quickly.
Well-structured text also creates better context if the post surfaces outside the app.
- Clear hierarchy
- More readable slides
- Better context
- Stronger search cues
How to Structure It
Use short headline-style subtitles, strong supporting phrases, and slide-by-slide progression so the text tells one coherent story.
- Headline first
- One idea per slide
- Keep phrases short
- Match the caption topic
