A quick test recently confirmed that when a customer borrows your ebook and reads it through the Kindle Unlimited program, that counts as a sale the same way as if they had purchased your Kindle book directly. To demonstrate this here are is the salesrank data for the test book:
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.

This is just a quick update to let you know that the background checks that power the hourly data collection for NovelRank have been completely rewritten. While they have had improvements and tweaks over the last 6 years, this new design is leaps and bounds better since being rewritten.
- Each domain runs its own independent script. Previously, only Amazon.com and Amazon.de were independent. This means no more books on say, Amazon.fr, that are active but don’t have a new sales rank for days or weeks due to script inefficiency.
- More books checked per hour. When NovelRank started, Amazon restricted API requests to a certain number per hour. Thus, NovelRank’s scripts were designed around that. Now, they are throttled based on API calls/second. Thus, the new scripts can slow down when Amazon asks, but otherwise make better use of every second in every hour to get sales rank data.
- PRO user books every hour, on the hour. Previously, NovelRank put PRO books first as promised, however it would then run the rest of the books which sometimes took more than 1 hour to complete. It would not check PRO books again until that was done, so PRO books would be first, but still may miss an hour of sales rank data. Now, as soon as it is a new hour, PRO books are processed, pausing any current processing, ensuring hourly sales rank data at a consistent time of the hour, each hour.
I get a lot of questions regarding what effects sales rank (now also known as best sellers ranking). I’ve done some testing on the matter to clear up some common sales rank myths, but I didn’t yet have an answer regarding the Kindle Direct Publishing (KDP) Select program.
What is the Kindle Owners’ Lending Library?
The Kindle Owners’ Lending Library is a collection of books that Amazon Prime members who own a kindle can borrow once a month, with no due dates.
I don’t understand, why?
Simply put, a borrowed book gets a portion of the monetary pool, and since it generates revenue for the individual or organization who published the item through KDP, it is considered a sale for the purposes for adjusting sales rank positively. Remember, sales rank is a measure of sales activity of all sorts, so consider this information when you are exploring royalty info (KDP Select payments may be dramatically higher or lower than your sales price).
