Publisher Rocket vs WriteLoom

By the WriteLoom editorial teamUpdated 2026-09-02
Key facts
  • Publisher Rocket: one-time purchase around $199, Amazon keyword and category research plus ad keyword lists.
  • WriteLoom: subscription workspace covering planning through selling, including metadata records.
  • Publisher Rocket estimates search volume and competition for Amazon keywords.
  • WriteLoom does not perform live Amazon keyword volume research.
  • The two are complementary: research in one, store and apply in the other.
Direct answer

Publisher Rocket researches Amazon keywords, categories, and competition, and generates ad keyword lists. WriteLoom is where the manuscript, blurb, categories, and channel records live. They are complements: Rocket tells you which seven keywords to use, WriteLoom is where those seven get recorded and reused.

Chapter i·Why it matters

Keyword research is a point-in-time activity and metadata management is ongoing. Writers who do the research and then keep the results in a spreadsheet lose them by the second book, and end up re-researching. Recording chosen keywords against the title, alongside the blurb they support, is what makes the research compound.

Chapter ii·What to include

  • Keyword and category research, which Rocket does and WriteLoom does not.
  • Chosen keywords stored against the title, not in a loose file.
  • Blurb and categories kept with the keywords they were chosen for.
  • A record of what changed and when, so you can measure it.
  • Per-channel metadata, since stores differ.
  • Re-checks scheduled, since Amazon's competitive landscape moves.

Chapter iii·Example

An author researched keywords in Publisher Rocket for book one and could not find them when book two launched. Recording them against the series in WriteLoom meant book three took twenty minutes instead of an evening.

In WriteLoom

A launch plan, not a launch day

WriteLoom keeps one metadata record per title, so the keywords you researched once are there for every store and every relaunch.
