Product Intent: Kindle book keyword research software
Publisher Rocket (PR) (which was previously known as KDP Rocket when it was created in 2016) is a well-respected keyword tool for self-publishers. It consistes of a downloadable application for either Mac or Micosoft Windows (no mobile OS version available) which allows users to research keywords and books, and to reverse-engineer successful book titles.
With a snappily designed front-end, the app is easy to use and, if the experience of users is anything to go by, seems quite popular. It is comparatively expensive at $97, but that is a single payment one-off price, and the app is very well supported with multiple software updates every year.
