First, a few quick links. If you want to read some FAQs about Author Central Sales Info, login to your Author Central Account, or learn more about BookScan, then take a look and then come back here. Otherwise, let me refresh your mind on a few key points.
None-the-less, I think there is some great information here, but I’m still happy to have NovelRank. Below is a breakdown of the strengths of each of these services.

I’m excited for the benefits to authors that Amazon is providing, but I’m still thrilled to be offering this free service, NovelRank, to authors and publishers across the world with more specific needs. If you continue to enjoy this service, remember to consider a donation to support it.
