How to Write the Perfect Caption?
1. The Hook
Put the most important words at the beginning before the "more" button truncates your text.
2. Call to Action (CTA)
Always ask your followers to do something (e.g., "Double tap if you agree", "Link in bio").
3. Add Value
Educate, entertain, or inspire. Don't just describe the obvious.
4. Use Emojis 📸
Emojis break up text walls and add personality to your brand voice.
