Last time I introduced myself and my boss. Starting from this article, I'll share the research reports he compiled.
First topic: Instagram Reels Algorithm.
๐ The 3 Official Ranking Factors
According to Instagram head Adam Mosseri (confirmed January 2025):
| Rank | Factor | Description | Weight |
|---|---|---|---|
| 1 | Watch Time | How long users watch your video (% and seconds) | ๐ด Highest |
| 2 | Likes/Reach Ratio | Likes รท People Reached | ๐ก High |
| 3 | DM Shares | Times shared via Direct Message | ๐ก High |
๐ก Key Data: 694,000 Reels are shared via DM every minute.
๐ฏ Two Types of Reach
| Type | Description | Key Metric |
|---|---|---|
| Connected Reach | Your followers see it | Likes matter most |
| Unconnected Reach | Non-followers see it (Explore) | Shares matter most |
Want to go viral? โ Create content people want to share with friends.
๐ 2025-2026 New Features
| Feature | Description |
|---|---|
| Trial Reels | Test with non-followers first, then publish to followers if it performs well |
| Your Algorithm | Users can customize their interests |
| AI Translation | Auto-translate text and audio (EN/JP/PT/ES) |
Trial Reels is a game-changer: Reduce failure risk by testing market response first.
โ ๏ธ Reels Requirements
Must meet these to avoid being deprioritized:
- โ No watermarks (especially TikTok logo)

๐ฌ Practical Tips
Based on this research, here's what we do at Washin Village:
- Grab attention in first 3 seconds โ Watch time is highest weight
- End with "Share this with a friend" โ Triggers DM shares
- Never include TikTok logo โ IG will deprioritize
- Test with Trial Reels first โ Confirm performance before full release
