It’s Not Just Keywords—It’s the DNA of Your Book’s Discoverability

You’ve written the book. Designed the cover. Uploaded the files. And…crickets.
If your sales are flat and your book is buried on page 12 of search results, you might have a metadata problem. Luckily, it’s fixable—and I’m about to show you how.

What Is Metadata, Anyway?

In publishing, metadata is everything behind the scenes that tells a platform (and a reader) what your book is about.

That includes:

• Your title and subtitle

• Author name and series name

• Book description (blurb)

• Categories and keywords

• ISBN, publication date, and format

• Even your cover file name and file size!

These bits and bytes determine whether your book shows up in the right place—or gets lost in the algorithm abyss.

Keywords: The Unsung Heroes of Discovery

You get 7 backend keyword slots on Amazon. Use them wisely:

• Think like a reader, not a writer.
  (They search “grumpy sunshine romance,” not “emotional character arc”)

• Use phrases, not single words
  (“witch academy fantasy” is better than “witch”)

• Avoid repetition.
  No need to repeat your title, author name, or genre if it’s already in your metadata.

Hot Tip: Use Google Autosuggest or Publisher Rocket to mine real reader search terms.

Categories: More Than Just a Shelf

Amazon lets you select 2 categories up front—but you can request up to 10 via Author Central after publishing.

• Start with broad genres (Romance > Contemporary)

• Then niche down for discoverability (Romance > Contemporary > Later in Life)

• Use ALL the categories available to you—it increases your odds of charting in at least one

Optimize Your Book Description for Humans and Algorithms

• Lead with a hooky first line
• Use bold or ALL CAPS for emphasis
• Break it into short, scannable paragraphs
• End with a compelling CTA (“Perfect for fans of…” or “Scroll up and grab your copy now!”)
