Free to use on any site, blog or newsletter template, commercial or not. The one condition: keep the visible “Data: Tropesmith” credit link back to tropesmith.com. Do not strip it, hide it or nofollow it — that link is what pays for the data.
Counted from the Tropesmith corpus — Goodreads reviews and shelf signals, parsed reader demand signals, BookTok video metadata and Amazon category economics — and recounted as the corpus grows. See every free Tropesmith tool, the full lane score list, or the 2026 Romance Demand Report.
