1.What they do
KDP says relevant keywords “can boost your placement in search results on the Amazon Store.” Together with categories, they tell Amazon where to shelve the book.
2.What KDP tells you to leave out
Words already in your title or other details, the names of authors not linked to your book, brands you don’t own, and Amazon program names like “KDP Select”. KDP also bans subjective claims, time-limited phrases and misspellings, and has “a zero tolerance policy for metadata that is meant to advertise, promote, or mislead.”
To choose them, read Amazon’s search suggestions in the Kindle Store or Books department, and use the phrases readers type. Shopperwords follows the department you pick. A phrase can carry several words, so one keyword like “cozy mystery with cats” covers what single words can’t.
