These statistics are provided as-is and are based on NovelRank’s sales estimates. Any inaccuracies are universally applied and should not affect the overall trends in the data. However, it is limited by the total books in NovelRank’s database, and thus is automatically biased.
TL;DR Grain of salt.
The very first chart was similar in shape across all domains, thus only one was included. All other charts are also summaries of only 2012 data and is shown for the top 3 Amazon domains tracked on NovelRank. Compared to the previous statistics post, these statistics are much less conclusive. For that reason, I encourage you to draw your own conclusions and post them in the comments below.
The last week with Amazon Kindle Edition books has been… interesting.
First and foremost, many books were placed on Amazon’s Kindle Store by publishers through MobiPocket instead of the Kindle Direct Publishing (KDP, formerly Digital Text Platform or DTP). Amazon has migrated these books to KDP, and in the process, those books were issued a new ASIN number, the unique number assigned to all products on Amazon.
What does this mean for you, the author? Your book may need to be added to tracking again using the new ASIN just as you did in the past. It is a mess created by Amazon not using the same ASIN, but alas, we move on.
Now for the good news!
For a while, some Kindle books that were not added to the Kindle Store through Amazon’s KDP suffered a penalty when it came to tracking: They were not accessible through the Amazon API, which is what allows NovelRank, SalesRankExpress, and other websites from accessing information about the book, including sales rank. For every other website, this is the end of the story. However, a few months ago I added code to NovelRank that worked around this limitation with Amazon.com and tracked the book’s sales rank anyway.
Well, that new code was added before Kindle books were added to Amazon.co.uk, and thus it only supported Amazon.com. Today, that is no longer the case. You can now track these Amazon.co.uk books on NovelRank. Be advised, this is about 5% as efficient a process as using Amazon’s API, but I feel it is a good idea that NovelRank continues to offer solutions for authors where other websites and publishers cannot provide the information. That’s why it exists after all.
With the August 5th announcement from Amazon that Kindle Edition ebooks will be now be available on Amazon.co.uk, NovelRank has been updated to support this new feature! You can now track your Kindle book sales on Amazon.co.uk by going to the book tracking page on NovelRank and adding your URL.
Don’t worry, if NovelRank is already tracking your Kindle Edition book, just grab the Amazon URL again or the book’s ASIN (highlighted below) and enter it into the tracking page. The system will search for a sales rank on Amazon.co.uk and add it if it is available.
Note: In most cases, your kindle book has not yet sold a copy, so no sales rank is present and NovelRank will not start tracking. As soon as you have a sales rank (a single sale will do it) on Amazon.co.uk, it can be added to NovelRank using the method above.
