Above is a typical add as shown on Amazon. This is usually in three parts, showing prices of your Paperback, Kindle and Audio Book. Some publishers give discounts on eBooks and Audio Books from time to time in order to promote their books. Not everyone begins with audio Books, but most prepare their Paperbacks and Kindle together and upload them to KDP at about the same time. The above image is as a guide only. You may check out similar books on Amazon for ideas.

You may also use Canva or your own software like Adobe Photoshop or Affinity Photo to create your Book Covers. Most images are freely available from Pixabay and others. Always check images are free to use or else contact the relevant company for payment. There are many artists and businesses on the Internet that will design your cover ranging from about £200 to £3000 depending on quality. Try not to use AI for designing your content and covers. Most publishers are not enthusiastic using such type of material, so beware.
