Retention

What is Retention?

Retention, or audience retention, is the percentage of a video that the average viewer watches before stopping. Platforms use it to identify where viewers drop off and to judge how well a video holds attention, which influences how widely the content is recommended.

When you'd use it

  1. 1When analyzing why a video underperformed despite strong initial reach.
  2. 2When editing a new cut and choosing where to trim to keep the pacing tight.
  3. 3When a platform's analytics show a specific drop-off point in a video.
  4. 4When comparing different video lengths to find what your audience finishes.
  5. 5When optimizing a series and deciding which episode format to repeat.

Example

A brand posts a thirty-second product demo and sees its retention curve drop from 100% to 45% at the eight-second mark, right when the presenter begins describing features. Pulling that narration forward to the first three seconds and moving the product close-up to the opening frame raises average retention to 68% on the next version, which the platform then distributes to a broader audience.

Use cases

  1. 1Locating the 20-second mark where most viewers leave a product demo and cutting that section.
  2. 2Checking retention curves across three video lengths to decide the optimal duration for a campaign.
  3. 3Tracking whether adding captions raises the average percentage of a video watched.

FAQ

What is the difference between retention and completion rate?

Completion rate is the percentage of viewers who watch a video all the way to the end, expressed as a binary outcome. Retention is the full curve: it shows the average percentage watched at every point in the video, so you can see the exact moment viewers leave, which the average percentage hides.
