A sophisticated way to refine or request more keywords

Since we are speaking about an AI tool the best part is that you can refine or request more keywords:

  • or Prompt the AI tool that “Suggest theme based book keywords!”
  • or Prompt the AI tool that “Suggest book keywords that fit the target age group!”

With this method you can get variety of keywords, targeting different aspects of the book. One thing is critical to always share context (title, longer description, excerpt etc.) with the AI to get enough input (knowledge) about your book. This will incrementally boost the quality of your keywords.

The nice thing is in case of modern LLMs that they are multimodal, means you can simply upload the current manuscript in PDF format, so they will basically “read” your new book offering the most suitable keywords!

  • Prompt the AI tool that “Suggest keywords based on the attached book manuscript!” and upload a PDF manuscript

How can we categorize keywords at all? What kind of keywords exists?

  • Generic Keywords: These are broad terms that can apply to many books. Examples include “fiction,” “nonfiction,” “guide,” “manual,” “story,” etc.
  • Genre-specific Keywords: These keywords are related to the genre or subgenre of the book. For example, “science fiction,” “historical romance,” “true crime,” “fantasy,” “young adult,” etc.
  • Theme-specific Keywords: These refer to the central themes or topics covered in the book. Examples could be “love,” “war,” “redemption,” “courage,” “betrayal,” etc.
  • Setting Keywords: Keywords that describe the setting of the story, such as “Victorian England,” “post-apocalyptic world,” “outer space,” “small town America,” etc.
  • Character Keywords: These focus on the type of characters involved, like “vampire,” “detective,” “alien,” “warrior,” “rebel,” etc.
  • Plot Keywords: These describe the plot or key plot elements, such as “time travel,” “murder mystery,” “coming of age,” “quest,” “heist,” etc.
  • Audience and Age Group: Keywords targeting specific reader demographics, like “children,” “teens,” “adults,” “Christian,” etc.
  • Event or Seasonal Keywords: These relate to times of year or events that might make the book particularly relevant, such as “Christmas,” “Halloween,” “summer reading,” “back to school,” etc.
  • Language and Cultural Keywords: These can be used to attract readers looking for books in specific languages or cultural contexts, like “Spanish language books,” “African American literature,” “Japanese culture,” etc.
  • Emotional Response Keywords: Keywords that hint at the emotional journey or response the reader can expect, like “heartwarming,” “thrilling,” “tear-jerker,” “humorous,” etc.
  • Author Keywords: If an author is well-known, their name can also serve as a keyword, especially for series or multiple works by the same author.

These types could be used as part of prompts in case of the above AI tool like 

  • “Suggest character keywords!”

How can we categorize keywords based on relevancy?

  • (A) Ultra specific – This type of keyword is very valuable, if the search density is over 100. As a marketer we prefer specific keywords when we are running Amazon Ads, but we use less often for Kindle Direct Publishing Keywords
  • (B) Specific – A low competition keyword which is very useful to target, these keywords are generally used for both KDP Keywords and AMS ads
  • (C) Focused – Focused keywords have higher competition but they aren't as crowded as Generic keywords. You may want to use these keywords both for KDP Keywords and AMS ads
  • (D) Generic – Try to avoid these keywords, unless you intent to run a push AMS campaign to get a high amount of impression. Please note these AMS campaigns have low ROI (Return of Investment) in short term.
