VoiceRankVoiceRank: one 0-100 measure of how strong a podcast booking someone is, built from four signals (Presence, Reach, Pull and Authority), each ranked against every other rated voice. Recomputed nightly; the arrow is the week-over-week change.
Unrated: not enough outside guesting yet to score fairly (needs 3+ appearances across 2+ shows, plus corroborating signals). It is an absence of a reading, not a low one.
Why unratedNot scored yet: VoiceRank needs 3+ guest spots across 2+ shows. We have 1 across 1.
