🎯 Reach quality

Subscriber activation · Exceptional

31.9%

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

-50%

Recent videos average 7.2K vs an all-time 14.4K/video — recent uploads run below the all-time norm — much of the lifetime views sit in an older catalogue.
