Where Publisher Rocket wins
- Keyword data is its core strength. Search volume, competition scores, and generated AMS keyword lists. This is the feature most buyers purchase it for, and KQS deliberately does not offer it.
- Category research at scale. 19,000+ categories versus our 9 hand-verified ones.
- Track record. 117,000+ authors, free updates, a 30-day money-back guarantee, and a new automated Rocket Report (September 2026) that writes up keyword and category research for you.
Where KDP Quick Scout wins
- No context switching. The verdict appears on the Amazon page you are reading, not in a separate app you have to copy ASINs into.
- Explained conclusions. Every analysis returns PURSUE, WATCH, or REJECT with the evidence and risks spelled out, not only raw numbers.
- Monitoring, not one-off lookup. Tracked books keep snapshot history and refresh automatically, so you see movement over time.
- Listing context on the page. Multi-format pricing (Kindle, paperback, hardcover, and the rest) and a warning when you track a different format of a book you already track.
- 14 marketplaces where Publisher Rocket covers 8.
Honest limitations
KDP Quick Scout does not show keyword search volume, and we do not plan to. Every number we display is measured from live Amazon pages or the data you provide. If a metric cannot be observed, we leave it out rather than estimate it. For volume-based keyword data, Publisher Rocket remains the stronger choice.
