Facebook doesn't know whether you sold a book.
It knows someone saw your ad. It knows someone clicked it. It knows what that click cost you.
Then the reader lands on Amazon, and Meta loses them completely.
Everything after that point is a blank. Which means every number on your Facebook Ads dashboard is describing the doorway, not the sale.
Most authors are running their entire business off numbers that stop at the doorway.
