Every video platform reports view counts, because view counts are easy to produce and pleasant to look at. They are also close to useless on their own. Four other numbers do the actual work.
1. Completion, not plays
A play is somebody pressing a button. Completion is somebody staying. The ratio between them tells you whether the thing you published was what the thing you promoted said it was — and a title with a high play count and low completion is usually a marketing problem wearing a content costume.
More useful still is where people stop. A consistent drop at the same timestamp across thousands of viewers is a specific, fixable fact about that asset.

2. Return rate in the first two weeks
Whether somebody comes back within two weeks predicts nearly everything downstream. It is the earliest reliable signal that the catalog is deep enough and that the recommendations are finding it.
It is also the number most damaged by a thin library. A service can acquire its way to a good month and cannot acquire its way out of nobody having a second thing to watch.
3. Churn, by cohort
An overall churn figure averages together people who joined for one event and people who have been there two years, which tells you about the mix rather than the product. Churn by joining cohort tells you whether what you changed in March worked.
The related number worth watching is what people watched in the week before they left. It is usually nothing, and the two weeks before that is where the intervention belongs.
4. Revenue per viewer, across every model
If subscription, advertising and pay-per-view are reported separately — which they usually are, because they often come from separate systems — then nobody can answer what a viewer is worth. That makes it impossible to say whether moving a title behind a paywall helped, because the ad revenue it stopped earning is on a different page.
The reason this is a platform question
None of these can be assembled from nine app analytics dashboards that count differently and cannot see each other. They require one place where playback, entitlement and revenue are the same set of events. Services that cannot answer these questions are rarely uninterested in the answers; they usually just bought a stack that cannot produce them.
