Channel Health Check
Enter a channel's three public numbers to see the two ratios that explain it best, and the grade they produce.
What this is
A channel health check grades a channel on two ratios you can compute from public numbers: total views divided by subscribers, and total views divided by video count. The first shows how active the existing audience is — whether the people who subscribed actually watch. The second shows how consistently each upload performs, independent of channel size. The grade is a simplification of those two ratios, useful as a starting point for a diagnosis rather than as a verdict.
The formula
views per subscriber = total views ÷ subscribers · views per video = total views ÷ videos
- total views — lifetime views across every video on the channel.
- Grades from A+ to D come from both ratios, weighted equally.
How it works
A views-per-subscriber ratio under 10 on an established channel usually means the audience has stopped watching — either the content direction changed, or the subscribers arrived from one viral video that does not represent the rest. A very high ratio, above 500, usually means the opposite: the content reaches far past the subscriber base, typical of channels whose traffic comes from search or from Shorts.
Average views per video misleads when one video dominates. A channel with 200 uploads where a single video carries 80% of the views looks healthy on the average, while the other 199 underperform. If you know one video ran far ahead of the rest, run the numbers again without it for an honest picture.
Neither ratio measures revenue, retention or growth. A channel with strong ratios but flat growth has a distribution problem rather than a content problem — and that distinction decides which fix is the right one.
How to use it
- Enter the channel's three numbers Subscriber count, total views and video count — all three are public on a channel page.
- Read both ratios Views per subscriber explains audience activity; views per video explains upload consistency.
- Use the grade as a starting point A low grade on just one ratio points at a specific problem, which is more useful than the overall letter.
Common questions
- What is a healthy views-per-subscriber ratio?
- Between 50 and 200 generally indicates an audience that still watches, on a channel a few years old. What counts as normal depends heavily on age and traffic source: new channels always show high ratios because they have few subscribers, and search-driven channels can sit in the hundreds with nothing wrong.
- Does a low grade mean the channel is bad?
- No — a low grade means those two ratios are low, and that can happen for reasons unrelated to quality. A channel that recently changed direction, one with a large back catalogue, and one whose subscribers spiked from a single viral video will all grade low while making strong content.
- Can I use this to assess someone else's channel?
- Yes — all three numbers are public on any channel page. That is what makes these ratios useful when assessing a potential collaborator or a channel you are considering advertising on: both can be verified without access to private analytics.
Notes
- The calculation runs in your browser. No figure is sent to a server.
- The grade summarises two ratios; it is not an overall judgement of a channel's quality.
