Instagram Ad Best Practices (2026)
Reels Dominate Reach
Instagram Reels receive 3-5x more impressions than Feed posts. Make Reels your primary ad format for maximum visibility.
First 3 Seconds Rule
Your Reels hook must land in the first 3 seconds — use a question, visual conflict, or surprising statement to stop the scroll.
1080p Minimum
While 720p is technically accepted, always upload at 1080p or higher. Mobile screens are sharp enough to notice low resolution.
Captions Are Essential
85% of users watch without sound. Always add captions. Reels with music also see higher completion rates — use both.
