Definition: Video completion rate is the percentage of views in which a video was watched all the way to the end.
Also called: VCR, completion rate, view-through rate

Video completion rate = completed views ÷ total views × 100Completion rate only counts viewers who reached the end. Average view duration tells you how long people watched on average, and average percentage viewed expresses that as a share of the video’s length. A 2-minute video can have a modest completion rate and still hold most viewers for 90 seconds, so read the two together.
Shorter videos finish more often, so completion rate is only fair to compare between videos of similar length. A 15-second clip and a 10-minute tutorial are doing different jobs. For long videos, the retention curve (where people drop off) is more useful than a single completion figure.
A 30-second TikTok gets 20,000 views, and 6,400 of them reach the last frame. Video completion rate = 6,400 ÷ 20,000 × 100 = 32%.
Watch time is the total amount of time viewers spent watching a video or channel, usually reported in minutes or hours.
Short-form video is vertical video, usually under three minutes, made to be watched full screen on a phone in a feed that plays the next clip automatically, such as TikTok, Instagram Reels and YouTube Shorts.
A hook is the opening of a post (the first line of text, the first slide or the first seconds of a video) designed to make people stop scrolling and keep reading or watching.
Engagement rate is the percentage of people who interacted with a post (liked, commented, shared, saved or clicked) out of the people who saw it or follow the account.
