Guide to Kindle Content Quality

Content published through Kindle Direct Publishing is held to the high standards customers have come to expect from Amazon. If readers tell us about a problem they've found in your eBook, we'll make sure you know about it and point you in the right direction to get the problem fixed. The information listed here will help you understand the types of quality issues we see most frequently and will give you an idea of what you should be paying close attention to when building your eBook. 

Note: Since Kindle Direct Publishing (KDP) aims to provide the best possible tools for independent publishers and the best experience for readers, we have a zero tolerance policy for any book content meant to advertise, promote, mislead, or that doesn't accurately represent the contents of the book. Please follow the guidelines below to ensure your book's content, including cover art, metadata, and product description do not result in inaccurate or overwhelming search results, or impair readers' ability to make good buying decisions.
