I don’t get it. I really don’t.
Looking at my Amazon sales ranks it would seem that selling copies of the books lowers my rank and not selling them raises it.
No I don’t mean my numbers get closer to 1 in the former, and further in the latter … I mean my chart-toppingness decreased with sales and increased without them.
I wish I were kidding, but one example involved going down several ranks after selling four copies in five and a half hours. Not bad, actually, but has been better. I wouldn’t have thought anything of it, as I said, could be better. Except over the course of another six hours I sold zero copies and my sales rank improved.
I’ve a terrible feeling that Amazon’s algorithm for their rankings has a divides where there should be a multiplies or vice versa. Or an add where it needs a subtract or similar. That has to be it. And remember folks, the people doing this math are probably the same programmers responsible for the security of your purchase, account, and payment information. I know I’m impressed.
