🎯 Reach quality

Subscriber activation · Exceptional
32.6%
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
-25%
Recent videos average 931.1K vs an all-time 1.2M/video — recent uploads run below the all-time norm — much of the lifetime views sit in an older catalogue.
