I'm launching an e-book on Amazon this week for makers. What are the best ways to promote it?

Good plan, thanks for sharing. I would also recommend gathering a preliminary audience, and it is also better to read the amazon terms and conditions, and the rules for which it is better to present a book there. In case of problems, just use amazon customer service number to get solutions

Build an audience before launching. Ask for presale (validate the idea). Sale on your website. Sale on Amazon - I would go this way.

The best promotion is to get get reviews on amazon to promote yourself. There is a service like SageMailer, which can help you if you can't. After all, it is one of the most effective Amazon review services. Try, experiment, try to understand your client, put yourself in his place. And then you will not only get your reviews, but also increase your sales, through repeat purchases.

For each product, you'll need to fill out cards detailing the characteristics, features, and benefits to attract customers. Your book is no exception. Also check out the information on this website. Although this method does not require much investment, it will take a lot of time to promote the site and create a theme design. A referral program is a profitable way to trade if you have no starting capital. In addition, it is a good advertisement for your own site, which will attract more active users to the page.
