Last time I covered Instagram Reels. Now let's talk TikTok.

Bottom line: Since 2025, shares and saves have overtaken likes in importance.


📊 Core Ranking Factors

Rank Factor Description 2025 Change
1 Watch Time & Completion How long they watch, if they finish Stays highest
2 Shares & Saves Sharing with friends, saving for later đŸ”ē Weight increased
3 Comments Discussion and engagement Stays same
4 Likes Just liking đŸ”ģ Relatively decreased

💡 Shares and saves mean "this is worth recommending" or "I want to see this again" - more valuable than casual likes.


đŸšĢ What TikTok Doesn't Care About

TikTok completely ignores these factors:

  • ❌ Your account's past performance
  • ❌ Your follower count
  • ❌ Whether you've had viral videos before

This means: New accounts have equal opportunity to reach massive audiences if the content is good enough.


🆕 2025 Algorithm Updates

Update Description
Production Quality Lighting, audio, editing now affect recommendations
Long Videos Rising 1-3 minute quality content getting more reach
Stricter Moderation Since Sept 2025, cracking down on misleading content and undisclosed ads

📏 Optimal Video Length

Length Best For Effect
11-18 sec Viral spread 🔴 Highest completion rate
21-34 sec Product demos Balance of content & completion
30-60 sec Tutorials Good for valuable content
60-180 sec Deep content Started getting push in 2025

âš ī¸ After 35 seconds, drop-off rate increases dramatically.


đŸŽŦ Practical Tips

Based on this research, here's what we do at Washin Village:

  1. Aim for completion rate → More important than likes
  2. Design share incentives → "Tag your friend who does this"
  3. Leave open-ended questions → Bait comments and discussions
  4. Invest in production quality → No more noisy audio
