Demand Snapshot

Paranormal Romance remains the dominant commercial channel for vampire fiction, averaging 411 estimated sales per day across the top 20 with a power index of 61.7 — but it is a Beaten Track Mainstream category with 149k competing titles and a high saturation-to-competition ratio of 2.75, meaning discoverability requires differentiation. The Literature & Fiction Horror node runs slower (248 sales/day, power index 54.2) but holds 318k titles and a very low STC ratio of 0.78, signalling genuine reader appetite relative to supply and making it a viable secondary browse node. Vampire fiction is not accelerating dramatically but is holding steady with strong baseline demand; the opportunity lies in under-served tonal and structural niches rather than chasing overall volume. Keyword signals from the horror cluster are noisy and malformed in this pull, so keyword-level velocity calls are withheld.
