🎯 Reach quality

Subscriber activation · Strong

10.1%

Share of subscribers who watch a typical recent video (avg views ÷ subscribers) — the real reach behind the subscriber count, and a quick check on whether those subscribers are still active rather than a vanity number.

Recent vs all-time

-63%

Recent videos average 5.7K vs an all-time 15.3K/video — recent uploads run below the all-time norm — much of the lifetime views sit in an older catalogue.

Median 5.4K — the reliable floor a brand can expect, not just the headline average.
