Ranked by the number of demand signals that mention each trope across Goodreads reviews, Amazon reviews, BookTok comments and captions, Reddit posts and Amazon Q&A, among the live tropes in Tropesmith's romance taxonomy. 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. Each signal gets a rarity tag (common, underserved or novel) from the text of that review or post alone; the classifier is never shown what is on the shelf. A tag points at where to look. It does not prove that no book answers the signal. Genre labels, story-structure tags and tags outside the taxonomy (for example Second Chance Romance, 77,558 signals, which the taxonomy does not list) are not ranked. How we count.
Found Family leads the romance board at 327,995 demand signals. Trauma Recovery closes out this ranking at 24,796 — still enough to track, just a smaller slice of a corpus this size. The median across these 12 tropes is 44,394, with 6 of 12 at or above it: the list is front-loaded toward a handful of high-volume tropes with a longer tail behind them.
The tagged share runs from 17% (Banter) to 64% (Trauma Recovery). It is the classifier's judgement of each mention, made without seeing the shelf, so a high share is a reason to look at comp titles for that trope, and a low share means the classifier tagged fewer of its signals that way.
By the number of demand signals that mention them, the top three romance tropes Tropesmith tracks are Found Family, Slow Burn, Forced Proximity (counted 4 November 2026). Full ranked list above.
966,852 trope mentions across the 12 tropes on this page; a signal that mentions several of them counts toward each. Found Family alone accounts for 327,995 of those.
Trauma Recovery, at 64% of its demand signals; the lowest is Banter at 17%. The tag is Tropesmith's classifier reading each review or post on its own, without a view of the shelf, so use it to decide what to check against comp titles.
