Reels
Reels are Instagram's short-form vertical video format (up to 90 seconds in 2026). They are the dominant organic-reach surface on the platform, accounting for roughly 60% of total time spent in the app and 80% of new-follower acquisition for accounts under 100k.

Instagram has actively reweighted its algorithm toward Reels since 2022, and that trend accelerated in 2025–2026. Static posts and carousels still drive saves and brand affinity, but Reels are where new audiences are found.
Three signals dominate Reels ranking: completion rate (full-watch %), rewatch rate (impressions ÷ unique viewers), and shares. A view that doesn't reach the 75% mark counts as a soft negative signal.
The most efficient growth-engineering pattern in 2026 is publishing 3–5 Reels per week, paired with a small early-views boost on each to clear the algorithmic test threshold and unlock the recommendation tier.
