The Amazon KDP long-tail keywords true crime readers actually search: cold case investigations, serial predator case files, sex crimes investigations, and unsolved murder books. True crime readers search by case type and outcome, not the genre label alone, so a single-word "true crime" keyword wastes a slot that a specific long-tail phrase would win.
Write the keyword as the case type, not the genre. "Cold case investigation book" and "sex crimes investigation true story" outrank "true crime" alone because they match what a reader is already looking for.
High search volume, low competition long-tail phrases in this niche usually pair a case type (cold case, serial predator, forensic) with a format word (case files, investigation, true story).
Cite your sources. Court records, journalism archives, and named investigators give a true crime KDP listing credibility that generic "shocking true story" copy does not.
Podcast crossover is real in this niche. readers who follow true crime podcasts convert well if your keywords match the case type they already follow.
Use these as variations in your 7 KDP keyword fields to capture a wider range of searches.
