Melweb Marketing Publishing Tools
KDP Category Research
Marketplace-specific research tools designed to help self-publishers research KDP category choices faster, understand full selector paths and spend less time clicking through menus when a book is ready to publish.
MAKE THE FINAL KDP STEP EASIER
Your book is ready. Category research should not send you back to square one.
After writing, formatting and preparing your book, the last thing you need is to spend ages clicking through category branches, trying to remember which route led where, or assuming eBook and Paperback choices are identical.
Melweb Marketing category tools are designed to make that final research job clearer, quicker and easier to repeat whenever your next book is ready.
Use Search & Highlight to bring matching category terms to your attention instead of hunting manually through long lists.
Review full selector paths so a category name is not judged out of context.
Research eBook and Paperback data separately instead of assuming the same choices exist in both selectors.
SEPARATE RESEARCH FOR SEPARATE MARKETPLACES
Choose the edition that matches where you publish
Amazon.co.uk and Amazon.com can have different category structures, so each edition is kept marketplace-specific rather than mixing UK and USA research together.
Amazon.co.uk KDP Category Research
Built from the signed-in Amazon.co.uk KDP selectors captured and verified on 11 September 2026.
3,995 selectable eBook placements and 7,299 selectable Paperback placements, plus Search & Highlight, full selector paths, format comparison and a complete Product User Guide.
Amazon.com KDP Category Research
The planned USA edition will use fresh Amazon.com KDP category data while keeping the same easy research system and clear workbook structure.
UK and USA data will remain separate, so you can research the marketplace you are actually publishing into.
