In the comments to the post where Charlie introduced me, I asked if anyone had a topic they wanted me to blog about. Andrew Suffield said he would be interested in hearing how the guest-blogging gig affects sales of my books. I confessed to being somewhat interested myself and I thought I'd look at the numbers.
Amazon.com shares Bookscan numbers with authors, so I can compare sales for the week ending 2/13 (the day Charlie wrote the introductory blog post) and the week ending 2/20, which is the last one they have data for. I can also tell you that the numbers for that last week show a jump of...
::cue dramatic music::
Forty books even--22 for Child of Fire, 18 for Game of Cages.
Not that Bookscan covers every sale. Venues it doesn't report: ebook sales, sales outside the U.S.A., stores that refuse to share numbers with Bookscan, and probably a bunch of others I don't know about. Estimates are that Bookscan reports anywhere from 50%-80% of actual sales and it's impossible to judge where my books fall in that range.
To muddy things further, some other things have popped up that would have driven sales, so it's possible that not all those forty sales might have come from here.
Anyway, the point I'm making is: that's the best number I have, but it's not that accurate and it's not terribly important to me. What is important is that I've enjoyed guest-blogging here. Thanks for having me.
