1. Instagram Reels (Primary Growth Engine)

Reels remain Instagram’s #1 discovery feature. Unlike posts, Reels are heavily pushed to non-followers through the Explore page and Reels tab.

Best practice:

1. Keep videos 7–15 seconds

2. Use trending audio

3. Add captions on screen

4. Hook viewers in the first 2 seconds

Reels are currently the fastest way to go viral on Instagram.
