Sales Ranking
Best Seller and Category Ranks are based on sales of your book relative to the sales of other books. A book ranking #1 in Mystery & Thrillers is the best-selling book in Amazon’s Mystery & Thrillers category. A book with a Best Seller Rank of #1 is the best-selling book in Amazon's Books store. Every book will have a Best Seller Rank after it has sold at least one copy, but Category rankings will only appear in the Product Details section of a book's detail page if the book is ranked within the Top 100 books in its category. A gift sale counts towards a sales rank only if it's redeemed within 24 hours by the recipient.
Rankings are updated hourly but may take 24-48 hours to appear after the first completed sale. Rankings reflect newer and historical sales of every book sold, with recent sales weighted more heavily. So if other books have recently sold more often than your book, your book's Best Sellers Rank may stay the same or even drop. Your sales rank can also change even when its sales stay the same. This happens when other books experience a decrease in average sales. So even when your book's sales rate stays the same, your rank may improve compared to the rank of other books.
When we calculate Best Sellers Rank, we consider the entire sales history of a book. Monitoring your book's Amazon sales rank may be helpful in gaining general insight into the effectiveness of your marketing campaigns and other initiatives to drive book sales, but it is not an accurate way to track your book's sales or compare your sales in relation to books in other categories.
The ranking for books with consistent selling histories that have been available on Amazon for a long time may fluctuate less than the ranking of new books, or books whose sales histories aren't as stable. One sale of a very popular book may not influence its rank much at all, but one sale of a lower volume book may significantly improve that book’s rank.
Your book's sales rank may also improve if customers read pages in your book through the Kindle Owners' Lending Library or Kindle Unlimited. Visit our Free Book Promotions Help page for more information.

Free and Paid Rankings
In the Kindle Store, the Best Sellers Rank is divided into Free and Paid lists. If you enroll in KDP Select, your book will have a ranking in the Free list during its free promotional period. Once the free promotion is over, your book's previous Paid rank will influence its new rank when it enters the Paid categories again.Your book's sales rank may also improve if customers read pages in your book through the Kindle Owners' Lending Library or Kindle Unlimited.
