What are the statistics on Brian D Smith's ebook sales on Amazon?

There is no public, reliable source that shares specific statistics on my ebook sales on Amazon (units sold, revenue, rankings over time, etc.), and I do not disclose those numbers myself.

If you are asking to evaluate credibility or impact, it might help more to look at verified reviews, ratings, and how long the book has remained available and active on Amazon.

Are you trying to gauge reach, or are you considering publishing your own ebook and wondering what is typical?
