Strong structure increases AI citation chances and user readability. Focus on:

Q&A formatting: Pose a question in caption, answer succinctly.
Bullet lists and numbered steps: Easy for AI to parse and users to scan.

Q: How do I grow tomatoes in pots? 🍅  
1️⃣ Choose 12" deep containers  
2️⃣ Use potting mix with compost  
3️⃣ Water daily, fertilize weekly

This format is favored by AI for featured snippets, enhancing discoverability in both social and AI-generated search.
