Prices in USD from each vendor’s own site, checked October 7, 2026. Searches: US Google searches a month for the product’s name, with the change over 12 months. Score out of 10, by one published formula; nobody pays to be listed.

How to choose a KDP tool

Research before you publish, or tracking after?

Two different jobs share this list. Publisher Rocket, KDSpy, BookBeam, Book Bolt and Titans Pro help before launch: which keywords readers type on Amazon, which categories a book could rank in, and how many copies competing books sell. ScribeCount and BookReport help after: they gather your own sales and royalties from KDP and other stores into one dashboard. Few tools do both.

Pay once or every month?

Publisher Rocket ($199) and KDSpy ($79) are one-time purchases; Publisher Rocket’s homepage warns it may move to a yearly subscription. BookBeam, Book Bolt and Titans Pro are subscriptions, with Titans Pro’s free plan as the way to try one. If you publish a few books a year, a one-time tool used at each launch may cost less over time than a monthly one.

Desktop, web or on the Amazon page?

Publisher Rocket is a desktop app for Windows, Mac and Chromebook. KDSpy is a browser extension that works on Amazon’s own search and product pages; BookBeam, Book Bolt and Titans Pro add extensions to their web apps.

Try the free tools first

Before paying, our free tools cover part of the same ground in your browser: the KDP sales calculator turns a Best Sellers Rank into estimated daily and monthly sales, the category finder searches Amazon’s book categories, and the keyword organizer sorts your seven KDP keyword slots. Our guide to Amazon book categories explains how category choice works.

How the BookBird Author Score works

Built for self-published authors, from facts anyone can check: each vendor’s own pages, read on October 7, 2026, and US Google search volumes (Google Ads data via DataForSEO). Nobody pays to be listed, and no score is adjusted by hand. We did not test the apps by writing a book in them; the score measures what they do for an author, what they cost and how widely they are used.

Author jobs, 50 points. Each category has a list of jobs an author needs that kind of software to do. A job counts only when the vendor’s own pages say the product does it; a job they do not mention earns nothing, and the product page says which ones.
- KDP research & sales tracking: amazon keyword search estimates, category finder, sales estimates for competing books, amazon Ads keyword lists, your own royalties in one dashboard, amazon stores outside the US and works on the Amazon page.
Cost, 25 points. What one year costs a single author on the cheapest plan with a USD price. A one-time licence is spread over 3 years. A free plan, or a platform that takes no upfront fee, earns all 25; the dearest product in the category keeps 5.
Adoption, 25 points. How many people in the US search Google for the product by name each month: 20 points on a log scale against the most searched product in the category, and 5 for the trend, comparing the last three months with the first three of the year.

The score is the points earned divided by the points that could be checked, on a 10-point scale. A part with no data (no USD price, no search volume) is left out rather than guessed. How long a product has existed is not scored: few vendors state it. Review sites are not used: for most of these products the profiles rate the whole company or hold a handful of reviews.

Questions

What is the best KDP keyword tool?

The list above ranks them by the Author Score. Publisher Rocket is the best-known one-time option; BookBeam and Book Bolt are subscriptions with a web app and a Chrome extension.

Is Publisher Rocket worth it?

It is a one-time $199 with a 30-day money-back guarantee, and it covers keywords, categories, competitor sales and Amazon Ads keyword lists. Its own page says it may become a yearly subscription.

How do I track my KDP sales across stores?

ScribeCount and BookReport collect sales and royalties from your accounts into one dashboard. KDP’s own reports show Amazon only.
