TikTok Algorithm and Video Length

TikTok's algorithm considers multiple factors when determining video reach, and length plays a crucial role in several key metrics:

How Video Length Affects Algorithm Performance

Completion Rate Impact

• Videos watched to completion get higher reach
• Shorter videos = higher completion rates
• 15-30 second videos often achieve 70%+ completion
• Videos over 60 seconds see completion rates drop
• Algorithm prioritizes high completion rate content

Watch Time Balance

• Total watch time also matters for reach
• Longer videos can generate more watch time
• Balance completion rate with total watch time
• 21-34 seconds hits the sweet spot
• Quality content can succeed at any length

Algorithm Optimization Strategy

Short Content (15-30s)

Focus on hook in first 3 seconds. One clear message. Strong visual appeal. Quick payoff.

Medium Content (30-60s)

Structure: Hook → Build → Deliver → Call-to-action. Keep pacing fast throughout.

Long Content (60s+)

Multiple hooks throughout. Clear value proposition. Segment into digestible parts.
