For book buyers, as you watch any book’s trek through the Amazon charts, it’s best not to base your buying decisions on those rankings alone.
Authors, ever wonder how to interpret book rankings on Amazon?
One sale can drop your book very low, even down below 100K. (That’s actually RAISE your book toward #1). It all depends on how many books are selling at the same time as yours. See it this way:
If you sell one copy, then everyone selling 2 or more copies will represent those sales between your ranking and the #1 slot.
Those selling fewer books than you, or no books at all, will place AFTER you out to infinity.
No real way exists to tell how many of your books sold at one time. Your book may languish at a certain position. That means no books are selling, not even yours. Any books that sell more copies than yours will continue to push your book’s ranking out, away from the #1 position, even if you’re selling well.
Sometimes just one sale of your book can take you nearer toward #1, but all that means is that no one else bought a book at the same time you did.
Amazon rankings are calculated every hour, so if no one bought a book during the hour yours sold, your ratings look real good. But watch, the next hour your rankings start to slide again due to sales of other books.
No real way exists to evaluate those ratings. Neither authors nor book buyers should give them much importance. An author could be selling a book an hour and if someone else sells two books per hour – especially if someone sells multi-copies in that same hour – though you’re making great sales, your rankings will slip.
