How to read Dr. John Campbell's numbers
Average views per video (277,865). This spreads lifetime views across every public upload, so older uploads that have had years to accumulate views are averaged together with recent ones. It is a useful scale check, not a prediction of how the next video will perform.
Views per subscriber (262.9). A rough measure of how much watch demand each subscriber represents over the channel's lifetime. Channels that reach large non-subscribed audiences — through search, Shorts or recommendations — tend to show a higher figure than channels that rely mainly on their existing subscriber base.
Upload cadence (~13.6 per month). Averaged across the channel's full history of about 19.3 years, so a channel that changed format or publishing pace along the way will not match this figure in any single recent month.
All figures come from public YouTube channel data and are refreshed on a schedule. They are research signals for comparison and context — they are not private YouTube Studio analytics, and they do not include revenue, watch time or audience retention. Read the full methodology.
