Self-publishing on Amazon is also worthwhile if you can leverage the hits and views generated by your eBook to fund another enterprise. In addition, the highest-paid authors on Amazon KDP are typically fiction writers. So, while I'm delighted I completed it, don't expect a sequel anytime soon. It is more probable that a video course will be used. That's not a bad thing though; more opportunities for income. If you do choose to publish with KDP, I recommend creating a separate account solely for this purpose. This will help you distinguish yourself from other authors using the same email address. Also, make sure to use a unique ISBN number for each book you publish. This makes it easier for readers to find your work in the Kindle store. There are several different types of eBooks available on Amazon including how-to guides, novels, poems, and non-fiction books. E-books are available in a variety of formats including PDF, EPUB, MOBI, and HTML. Each format has its own advantages and disadvantages so it's important to consider what type of reader will most benefit from your eBook before choosing one. For example, if you want your readers to be able to read your work on all their devices including phones, tablets, and computers then an e-book optimized for mobile reading experience is necessary. A desktop or laptop computer is better suited for longer documents.
