Why? As an author, you can create ads for eligible books that are published, claimed in Author Central, sold in the same marketplace where you plan to advertise, and follow Amazon Ads policies. For example, all advertising content must be appropriate for a general audience, and the book title, headline, text, or images must also be relevant and accurately represent the book advertised. Following these guidelines and policies will streamline your path to launching your campaign. Remember, just because you can sell your book on Amazon does not mean you'll be able to advertise it on Amazon.
