The latest month of the Historical (Regency) trend table holds 864 main-trope tags on demand signals. Baked from the lane trend table on 2026-11-05. The table’s latest month is the last month with rows and is usually only partly read in (reviews and posts are read some time after they are written), so its counts read low next to earlier months; compare tropes with each other, not with earlier months.
How the list above is worked out: each month, every trope in a lane is ranked by the likes and upvotes attached to its demand signals (a post’s likes count once for each signal drawn from it), taken from Goodreads reviews, BookTok comments and captions, and Reddit posts. A trope is listed when its average position in the later part of its monthly history is in the lane’s top fifth and differs from its average in the earlier part by less than 12 percentile points. Tropes need at least 12 demand signals in the lane. The ranking is by reader likes and upvotes, not by books, so it says nothing about how many books already cover a trope; check comp titles before you commit.
Counts are demand signals from Goodreads reviews, BookTok comments and captions, and Reddit posts (Amazon reviews and Amazon Q&A are not in this read) that name the trope as a main trope. A demand signal is one specific thing a reader asked for or praised in a review, comment or post, picked out by Tropesmith's classifier. One review can give several. How we count.
A high count says a trope is talked about at scale. It does not say how many books already cover it, or whether the angle you would write is one readers want. Check the comp titles on Amazon and in a sample Map before you commit. This is a thin slice of what a full Tropesmith Map does for your specific book.
