Heads Up: AMS KENP Read Data May Be Inaccurate

It’s been about half a month since Amazon launched its latest update to show KENP Read on the AMS Dashboard. In that time, we at Publishwide noticed some errors with the data.

Namely, we noticed that you may have more KENP Read on AMS than on KDP. 

How We Found This Error

We first noticed this error from Amazon at Publishwide when we were integrating thenew AMS data into our dashboard. Specifically, we noticed that on July 16th and July 31st, there were negative KENP read numbers (which shouldn’t be happening) for a single book in the .COM store:

We first noticed the negative page reads on Publishwide for a single book in the .COM store.

At first, we thought this had been an error on our end.

So we decided to dive a bit deeper into our data. We downloaded this book’s KDP and AMS data in the .COM store. As it turns out: the inaccuracy had come from Amazon!

We downloaded the KDP and AMS reports. The inaccuracy had come from Amazon!

Here is the same data in table form:


KDP Pages

AMS Pages







So our next question was: why was this number different? 

Why Your AMS KENP Read Might Be Different From Your KDP KENP Read

While there hasn’t been any specific information from Amazon yet about why your AMS KENP Read might be different from your KDP KENP Read, we do have some guesses:

Possibility 1 – Offline Page Reads Being Tracked Differently Between KDP and AMS

It’s possible that KDP and AMS tracks your Page Reads differently by virtue of how they track sales.

A quick rundown:

  • AMS tracks your advertised book for 14 days after it has gotten a click–including offline pages.
  • KDP tracks page reads on the day it happens.

This difference in how each platform tracks page reads may have played a part. Here’s an example:

  • Someone clicks your ad and downloads a copy of your book through KU on the 1st. 
  • They turn their Kindle off but read your book.
  • When they turn their Kindle back on 13 days later, KDP tracks any accrued page reads on the the 13th.
  • But on AMS, the pages are attributed to the 1st. Therefore, it’s possible for your AMS KENP Read data to be higher than your KDP KENP Read data. 

Possibility 2 – General Inaccuracy Due to KENP Read Being a New AMS Feature

The second–and far more likely–possibility is that because KENP Read is a new metric on AMS, Amazon is still squashing out any potential bugs within the system. We won’t know for certain if that’s the case, and Amazon certainly is keeping hush about it. 

What This Means for You

So what does this all mean? Does it mean that your royalty and data is wrong on Publishwide? Does it mean your data is wrong from Amazon? 

Not at all! 

Ultimately, your numbers still add up correctly, and you will be paid exactly what you have earned by Amazon on payday. 

However, we at Publishwide highly encourage you to dive into your own data and see for yourself if your AMS KENP read data contains the same inaccuracies as ours.
