How It Works
TikTok counts a completion when a viewer watches your video all the way through. This is the ultimate engagement metric — these viewers received your full message, saw your complete story, and experienced your entire call-to-action. Completion rates vary significantly by video length: shorter videos naturally achieve higher completion rates.
