I’ve just noticed a new feature on Amazon:
“Tag this book for Amazon search.”
It’s a way of telling Amazon, “When people search for a certain phrase, this book should come up in the results.”
So–just to pick a random example–suppose you feel that people who read Harry Potter might also enjoy reading The Government Manual for New Wizards. Yet you know that hundreds of millions of people read the former who have never heard of the latter. Night after night, you lie awake, worrying about the millions of poor lost souls who will never know the simple joy of buying one of my books.
