How do You Get Around Having no Reviews on Books and Create Confidence to Seller?
There are a few ways to help.
One is to make your book cover stand out. Big text, bold colors on the cover. As well as showing on your cover what is inside your book. Or add A+ content to the book.
Promote your book in many ways. Marketing by posting on Facebook, Pinterest, Instagram, etc.
Use Amazon Ads.
You can pay a YouTuber to mention it, or send YouTubers one of your books and maybe they will show it on their channel.
