Subtitle generator
Fiction subtitles have one job: tell a scrolling shopper which shelf this book belongs on. "A Small-Town Cozy Mystery" does that in five words. Build yours from a few details.
Give us a few details and we'll draft ten options.
Subtitle rules worth knowing
- KDP says title and subtitle together must be 200 characters or less, and the subtitle follows the same rules as the title.
- No sales-rank or promo claims like "bestselling" or "free". KDP prohibits them in the title field.
- KDP adds the colon between title and subtitle on your book page.
- Don't stuff it. A subtitle that reads like a list of keywords looks spammy to shoppers. Put the extra phrases in your 7 keyword boxes.
