Just What Does Amazon Sales Ranking Mean Anyway?

Brent Sampson has figured it out, and it’s remarkably unlike how one expects it to be calculated. Which in turn means that what it means is different than what one would suppose it to mean.

In actuality, the process is somewhat more convoluted than they let on. Only the top 10,000 books are updated every hour and the ranking does not depend upon the actual number of books sold, but rather, on a comparison against the sales figures of the other 9,999 books within that same hour. Simultaneously, a trending calculation is applied to arrive at a computerized sales trajectory. So, hypothetically, a book that held a ranking of 2,000 at 2pm and 3,000 at 3pm, might hold a 4,000 ranking at 4pm, even if it actually sold MORE books between 3-4 than it did between 2-3.

Books with rankings between 10,000 and 100,000 are recalculated once a day, rather than once an hour. Current projections, as well as historic sales information play a key role in these calculations. In fact, the predictive nature of the Amazon ranking system is what makes it possible for a newly-released book to outrank an older established title, even though the actual sales figures for the latter far exceed the former.

Happiness Shared Is Happiness Doubled (To The Power Of Two)

My day just got infinitely better, thanks to a series of good news shared over the past hour.

I love my friends. It feels so good to be this happy for other people, whatever the reasons.

Of course, I also sat down on the floor and cried because I was laughing so hard. It vaguely confused Liam.

ETA: Okay, here’s the first reason! I can share now that this individual has posted one of the bits of news himself.

ETA AGAIN: And here’s the second reason! (Yes, I’ve been stalking LJs for the past half-hour, can you tell?)

Why was I laughing so hard that I cried? Well, both these individuals had me edit their stories before they submitted them. And when I did these reads/edits, I was under the impression that only one of them would make it into the anthology, so when I got the first call I was happy but also sad for the other individual… who then proceeded to call me five minutes later to tell me that his story had been accepted. And I was also laughing because both of them called me and said, “I wanted you to be the first to know, because you helped make this happen.”

I love my life. I love that I had a small role to play in this incredible accomplishment for two of my friends.
