How Metadata Helps You find Readers on Amazon

What is metadata anyway?

Metadata is a fancy term for the data that describes your book, like title, description, subtitle, browse node categories and keywords.

Metadata helps more people see your book

Amazon uses your book's metadata to decide which readers will see your book. Keywords and browse node categories in particular can have a huge influence on how many readers will see your book online. The more people who see it, the more opportunities you have of making a sale.

Metadata convinces people to buy your book

After a reader finds your book, you need to convince them to buy it. Readers judge books by their visible metadata. Does the description and subtitle intrigue readers? The right words can move mountains (of sales).

Metadata needs to be optimized for Amazon's algorithms AND for readers viewing your book's product page.


The most effective metadata is optimized for Amazon search and for prospective customers. It needs to be crafted in a way that surfaces your book to the people most likely to become readers, and then convince them to make a purchase. This is no mean feat for a few bits and bytes of data, but time spent on metadata can reap some of the biggest returns of all marketing activities. So how do we create metadata that sells?

Capture Attention with the right description and subtitle

Whenever a reader comes across your book on Amazon, such as in a list of books in a search result, in a category listing or elsewhere, the book is listed alongside many other books. Each each of these books is competing with yours for the reader's attention and dollars. Authors can capture more of this limited attention by using the right words and phrases within their book's subtitle and description. Within each genre, certain words and phrases stand out, catching the reader's eye and prompting them to take a closer look. By tapping into these triggers and expressing them in metadata, author can give their book an advantage over competing books and increase the likelihood of a sale.


Position your book to sell with browse nodes, subtitle and keywords

At the most basic level, browse node categories position your book in a similar way as bookstores do - customers know what to expect when they browse the mystery and suspense aisle. Amazon gives readers and booksellers far more granular categories to group books, allowing a book to exist on many bookshelves all at once. But to sell more books means doing better than putting your book into the "correct" categories, it requires putting your book into the categories that will result in the most sales. Likewise, keywords and subtitles (which are considered a "super keyword" by Amazon search) - most authors only look for keywords that are "correct", and fail to keywords that are both "correct" and "targeted" to a book's specific readership.

create Congruent Metadata elements: an example

Certain topics dominate the best selling books within a browse node category. This may not always be evident from the name of the category, but is evident upon taking a closer look at the common themes and topics of the top books. For example, a psychic romance comedy may technically fit within the "Mythology" category, but after inspecting the top selling books in the category, the astute author may find that books with vampires, werewolves and shapeshifters dominate the list. After further investigation of other categories, our author finds a dominance of psychic fiction in the Paranormal Suspense bestsellers list instead, demonstrating that readers browsing this category are likely to be a better match to the book, meaning a higher chance of sales. She also notes that ghosts are popular within this category - her book deals with poltergeists but she had always focussed on the psychic angle. With this insight, she rewrites her book's description to include the ghost element of the story, understanding that psychics and ghosts resonate with readers browsing the Paranormal Suspense category. The metadata update puts her book in front of a more targeted audience, and highlights the elements of her story these readers are most interested in.

Understand what works for the competition

Finally, the smartest way to determine what works best for books like yours, is to analyze similar books by authors selling more copies than you are. In studying the competition, you'll begin to see patterns among the fonts, imagery, language, book length, prices, review topics and so on. If you can identify the best practices successful books utilize, you can apply them to your book and improve sales on Amazon.
