Are you a Kindle e-book writer and looking to publish a book soon? Well, finding the right category and keywords for your work is important to ensure that it sells. However, this is a tedious process, particularly if you’re doing on your own. Fortunately, there are many tools out there that can help you to ease and speed up the process. Kindle spy is so far the best tool in the market.

What is Kindle Spy?

KDSpy is a browser extension that helps Kindle publishers to discover hot niche opportunities. It makes that possible by reverse-engineering the bestseller category in the marketplace. The extension is only compatible with Firefox and Google Chrome. This tool offers the following benefits:

• Help you identify the suitable keywords for your book’s titles and subtitles
• Helps you know if there’s enough demand for your book’s idea before you begin writing
• Help discover how competitive different niches are and which ones disserve your attention
• It helps in spying competitors in your niche and replicating their success.
Doing this research manually could take you hours upon hours. But with Kindle Spy, this becomes a matter of minutes.
