Definition
TikTok video completion rate is the percentage of viewers who watch a video from start to finish, a key signal TikTok's algorithm uses to decide whether to promote content to a wider audience.
In Depth
Completion rate is TikTok's most important engagement signal. Videos with high completion rates get pushed to more users via the For You page algorithm. A video watched to the end by 60%+ of viewers will typically receive significantly more distribution than one where most viewers scroll away at the 3-second mark. Completion rate data is not available through TikTok's basic display API. Content creators see it in TikTok Analytics (in-app only), and third-party tools estimate it from proxy signals. Direct API access to per-video engagement metrics requires either TikTok's Research API (restricted to approved academic researchers) or commercial data providers. For brands and agencies, the practical approach is to analyze engagement ratios as a proxy: a video with high likes-to-views and comments-to-views ratios likely has strong completion rates. Using Scavio's TikTok endpoints, you can pull post-level engagement data (views, likes, comments, shares) at $0.005/credit and calculate these proxy metrics. Analyzing a creator's last 30 posts costs roughly $0.02-0.04 (4-8 credits depending on pagination) and reveals their typical engagement patterns. Compare against category benchmarks: fitness content typically sees 2-5% like-to-view ratios, while comedy content sees 5-10%.
Example Usage
A DTC brand analyzed 200 TikTok videos in their product category via Scavio (800 credits = $4.00). They calculated engagement ratios for each video and found that tutorial-style content had 3x higher like-to-view ratios than product showcase content, suggesting significantly better completion rates. They shifted their content strategy to tutorials and saw 4x more views per post.
