A month or two back, Amazon began sharing BookScan information with authors. I can now see how many copies of How We Test Software at Microsoft are selling (US only, and Nielsen BookScan only tracks the large-ish book sellers) – but it’s still sort of cool.
I can’t help but wonder who in Houston bought a copy, or why 4 copies sold in Washington D.C. last month.
I can also track ranking (only as far back as October 2009, I’m not as interested in sales ranking (the book seems to bounce quite a bit, but it’s still interesting to look at history. Sales rank from October 2009 to now looks like this:
Sales have been steadier than the sales ranks, and as such I expect that Amazon sales rankings are not based entirely on actual sales (links, page views, etc. all contribute (I think) to amazon rating).
Anyway – not sure what to make of it, but I’m pleasantly surprised to see that the book is still selling steadily. I think if we sell about a bajillion more copies, I can justify a second edition.
