This is just a quick post that helps out the majority of users of NovelRank. I was able to request an increase to my API calls/hour with Amazon.com, meaning that within 1 hour I can make 10,800 API calls rather than 3,600 API calls. This means that (especially for books that have sold a copy in the last few days), sales rank data is being collected 100% faster than 3 months ago (~19/day vs ~9/day). That means that sales estimates will be more accurate moving forward (still underestimated for bestsellers) since the sales rank data it is based on will be more reliably captured.
One final note, some are turned off by the 100 book limit for user accounts, even for PRO accounts. The above is the reason this exists, because the more books in the system by a few individuals, the larger the slowdown they can have for everyone’s experience. NovelRank has always been about helping out the little guy authors, and that won’t change even if it means leaving money on the table.
As a reminder, PRO customers always get sales rank checks 23 of the 24 hours each day, among many other benefits.
