How can switching Amazon Categories improve my book’s credibility? Here’s an example of a category switch than took me from rank #370 to #20 in a more relevant category.

My Freewriting for Travel Writers book was in the following three categories. My book was ranked low in each of the three categories.

  1. Amazon Best Sellers Rank: #187,710 Paid in Kindle Store (See Top 100 Paid in Kindle Store)
  2. #370 in Kindle Store > Kindle eBooks > Reference > Writing, Research & Publishing Guides > Writing Skills
  3. #935 in Books > Reference > Writing, Research & Publishing Guides > Writing > Writing Skills
  4. #1037 in Books > Reference > Writing, Research & Publishing Guides > Writing > Travel

I researched a better category and sent a request to Amazon and asked them to add me to the Writing, Research & Publishing Guides > Nonfiction category instead, and within 24 hours my book was moved to the Nonfiction category where my book was ranked #36.

  1. Amazon Best Sellers Rank: #198,519 Paid in Kindle Store (See Top 100 Paid in Kindle Store)
  2. #36 in Kindle Store > Kindle eBooks > Reference > Writing, Research & Publishing Guides > Nonfiction
  3. #400 in Kindle Store > Kindle eBooks > Reference > Writing, Research & Publishing Guides > Writing Skills
  4. #1074 in Books > Reference > Writing, Research & Publishing Guides > Writing > Writing Skills

The next day I sold just one book, my best seller rank dropped in half and I made the top 20 in the Nonfiction category: 

  1. Amazon Best Sellers Rank: #96,998 Paid in Kindle Store (See Top 100 Paid in Kindle Store)
  2. #20 in Kindle Store > Kindle eBooks > Reference > Writing, Research & Publishing Guides > Nonfiction
  3. #177 in Kindle Store > Kindle eBooks > Reference > Writing, Research & Publishing Guides > Writing Skills
  4. #495 in Books > Reference > Writing, Research & Publishing Guides > Writing > Writing Skills

The Impact:

  • I switched out of the Writing Skills category where I was ranked #370 (so I didn’t even appear on the Top 200 listed books), and requested a move to the Nonfiction category.
  • After getting into the new category I was ranked #36 (so appeared on the second page of the search results).
  • After selling just one book, I entered the first page of search results at rank #20.

So this one simple request has catapulted my book to a search results page giving it greater visibility within a niche populated with other books on the same topic.

The research was made painless and easy by using KDP Rocket and Kindle Spy.
