Keywords for books New
Only the searches about your book.
- Top keywords for your title and subtitle; rising ones searched more and more right now
- Opportunities: searched enough, but used by only 1 or 2 books on the first page — easier to rank for
- Missing from your book: the words your competitors rank for on page 1 and your listing does not use
- Phrases about other products ("shirt", "printable") are left out of the book list
- Brands and characters kept apart — they can get a book removed from Amazon

How to use the 7 KDP keyword boxes
- Each box takes up to 50 characters: use phrases buyers type, not single words
- Do not repeat words already in your title and subtitle — Amazon reads them already
- Never use brands, characters, other authors or words like "bestseller" or "free"
- Your title must match your cover: GizmoBloom keeps it as it is and improves the subtitle and the boxes
Then see what each sale pays with the free KDP royalty calculator, and make the book itself with the KDP coloring book maker or the puzzle book maker.
