Our keywords best practice advice is based on information gathered from across the industry, but it’s an inexact science without thorough guidance from Amazon. We often post the latest studies and advice on keywords in the Consonance community.

In general, carefully chosen keywords help discoverability of your ebooks on Amazon.

Keywords format

  • Keywords should be a string of words separated by semi-colons, for example: murder; magic; suspense; romance; Gothic; strong female lead; doctors
  • Amazon says that it accepts up to seven keywords or phrases and suggests putting them in a logical order
  • Avoid quotation marks. If you enter complex suspenseful whodunit, only people who type all of those words will find it. For better results, enter: complex suspenseful whodunit. Then, customers can search for any of those words.
  • Avoid very long keyword phrases. Amazon will ignore ALL keywords on a product if any one of the keywords is more than 250 bytes long.

Tips from Amazon*

  • Avoid repeating information covered elsewhere in the product’s metadata (title, contributors, etc.)
  • Single words work better than phrases, and specific words work better than general ones
  • Look at the left hand menu on Amazon for inspiration for keywords
  • Useful keyword types are:
    • Setting (Colonial America)
    • Character types (single dad, veteran)
    • Character roles (strong female lead)
    • Plot themes (coming of age, forgiveness)
    • Story tone (dystopian, feel-good)
  • Avoid time-sensitive statements (new, on sale, available now)
  • Avoid variants of spacing, punctuation, capitalisation, and pluralisation (80GB and 80 GB, computer and computers, etc.). Exception: Words translated in more than one way (e.g. Mao Zedong or Mao Tse-tung, Hanukkah or Chanukah

Tips from Consonance

  • Adding a good set of Thema codes can also help discovery on Amazon, in particular for time and geography aspects of your works, and this “frees up” keywords to focus on other areas of discoverability. Read more about Thema

Quality control

Consonance has a quality control measure to prevent wasting words and use of stop words that will be ignored by Amazon. The review gives you immediate feedback on keywords that are very similar to each other, the title, or one of the contributor names, and looks for individual characters and words that Amazon is going to strip out of the keywords anyway.

Consonance also includes an automated keywords review within the metadata checks of all works, and will flag any work that has fewer than three keywords. This check can be suppressed.

Final note:

Once your quality keywords have helped the book be discovered, it is the job of the rest of your metadata (cover design, title, descriptions, price etc) to close the sale. Keywords cannot help you with that.
