🎯 Reach quality

Subscriber activation · Exceptional
30.3%
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
-55%
