Amazon author central

Amazon offers a way to customise one’s own author page but also it now provides a nice feedback about sales, with geographic distributions of sales (retailers included) and evolution of amazon ranks as shown on the above snapshot. This is an improvement compared with the more rudimentary TitleZ which does not allow to tune the time window… For instance, I found that the most sales occured in San Francisco last month. Completely uncorrelated with my trip there last summer!
