Short-form concepts
Completion rate
What is Completion rate?
Completion rate is the percentage of viewers who watch a video all the way through to the end. A high completion rate signals strong viewer engagement and is used by social platforms as a factor in determining how widely a video gets distributed.
When you'd use it
- 1When diagnosing why a video got impressions but low reach or shares.
- 2When comparing two cuts of the same content to see which holds attention longer.
- 3When platform analytics show a drop-off at a specific timestamp.
- 4When testing a new video format to see if the pacing holds an audience.
- 5When deciding whether to trim the end of a video before reposting.
Example
A food brand tests two versions of a recipe video: a 20-second cut and a 45-second cut. The 20-second version achieves a 72% completion rate, the 45-second version 38%. The algorithm favors the shorter cut despite both containing the same core information, because the completion signal is stronger.
Use cases
- 1Checking whether a 60-second brand story needs its final 15 seconds cut.
- 2Comparing a fast-cut version against a slower edit to see which finishes more often.
- 3Identifying the exact frame where most viewers leave a product walkthrough.
FAQ
Is completion rate the same as retention?
No. Completion rate is a single number: the percentage of viewers who watch all the way to the end. Retention is a curve that shows the percentage of viewers still watching at each point in the video. A video can have a low completion rate but strong mid-video retention if a large segment drops at the very end.
