KDP keywords: how to fill the seven boxes

KDP gives you 7 keyword boxes. What to put in them and which words waste a box.

Checked November 9, 2026Plain text version

KDP lets you add up to 7 keywords. They help readers find the book when they search for words that are not already in your title.

What makes a useful keyword

  • Words a reader would type: the subject, the age, the occasion ("dinosaur coloring book for 4 year olds").
  • Short phrases rather than single words.
  • Words not already in your title, subtitle or categories; those are searched anyway.

Words that waste a box

Avoid praise, time-limited words, program names and generic words such as: "best", "bestseller", "bestselling", "free", "new", "sale", "kindle", "kdp", "book", "books". Never use other authors' names or book titles.
