What is the most important ranking factor for Instagram Reels in 2026?

Sends-per-reach (Direct Message shares) is the undisputed #1 ranking signal on Instagram. Content that users send to friends via private messages receives disproportionately higher recommendation velocity.

How does Meta penalize aggregator and repost accounts?

Meta automatically replaces reposted clips with the original creator's profile in recommendation surfaces, heavily curbing non-follower reach for re-uploaders.

Does adding hashtags still improve Instagram reach?

Hashtags now function primarily as categorical search tokens rather than reach multipliers. 3 to 5 hyper-specific niche tags combined with clear verbal/caption keywords perform best.
