Keywords are the new bookshelf.
People discover books through web search instead of browsing bookstores now. To help your book’s discoverability you want to use keywords (the words people might use to search for a book like yours) is as many places as possible.
Without sounding like a robot.
Consider using keywords in:
- Your title or subtitle (if appropriate)1
- Your book description
- Image names (rename your images with keywords)
- Alt text (use alt text to describe the image for unsighted viewers – don’t cram with keywords, but use those that are appropriate)
- Website
- Social media posts
- Hashtags
