The four ranking signals
According to Instagram's own engineering blog, feed ranking boils down to:
- Relationship — does this person interact with you (DMs, comments, profile visits)?
- Interest — has the viewer engaged with similar content before?
- Timeliness — newer posts win, all else equal.
- Usage patterns — how long and how often the viewer scrolls.
What this means in practice
Reach is a by-product of relationships, not hashtags. The accounts that DM, reply and comment consistently get shown first. Track how your likes respond to changes with the free LikeWave analytics report — the likes-per-post chart makes algorithm shifts obvious within a week.
Reels vs. feed in 2026
Reels still receive a discovery boost, but retention is now weighted more than shares: a 90%-watched 15-second reel outperforms a widely shared 60-second one.
