Completion rate measures how many of the people who started a title watched it through to the end, or past a defined threshold. It is a sharp signal of content quality and fit: high completion means the content held attention; steep drop-off points reveal where viewers lose interest.
Analyzed at scale, completion and the shape of the drop-off curve guide content strategy, episode pacing, and even recommendation weighting (a finished title is a stronger positive signal than a started one). For ads, completion of the content and of ad pods affects both experience and monetization. It complements watch time by showing not just how much was watched, but whether viewers saw things through.

Fora Soft Video Engineering Handbook
Completion rate shows whether a title lands, but a stream that stalls near the end can look like weak content in the report. The seven volumes cover the whole video stack; for reading completion rate start with Volume 3 on QoE monitoring, players, and ABR, then Volume 1 on encoding quality and Volume 2 on delivery latency. Written by Nikolay Sapunov, CEO at Fora Soft.
