Amazon.it (Italy) Sales Rank Tracking Now Available

Friday, August 5th, 2011

As of earlier this week, Amazon released the Product Advertising API for Amazon.it, Italy. Within a few hours, NovelRank was enabled for tracking sales rank on Amazon.it. If you want to add your book for tracking, just repeat the process you used when first adding your book: Copy and paste the Amazon link (can be from any Amazon domain, doesn’t have to be the Amazon.it link) into the Sales Rank tracking page. Make sure you check ‘Add Additional Domains’, and click the track button to finish the process. Within a few seconds, all of Amazon’s domains will be checked to see if updates for tracking are available. Enjoy!

Sales Rank Check Frequency Changes – Growing Pains

Thursday, March 17th, 2011

Starting today, a new structure has been put in place to ensure the longevity and speed of NovelRank continuing through year two and beyond. This is based on the frequency that NovelRank will check the sales rank for a particular book on a particular domain (.com, .de, .co.uk, etc.). I thought long and hard about this, especially as an author who sells from 1 to 10 books a month in some cases, and I think this will be valuable and fair to everyone.

Here is the breakdown:

  • If a book has been sold in the last 7 days on a specific domain, it will continue to have its salesrank checked hourly.
  • If a book has been sold in the last 14 days (but not the last 7), the checks will occur every 4 hours.
  • If a book has been sold in the last month (but not the last 14 days) on a specific domain, the checks will occur every 8 hours.
  • If a book has not been sold in the last month on a specific domain, the check will occur once per day.

It’s important to note that as soon as a sale is made, the clock is reset and the book goes back to hourly salesrank checks! It is also domain specific, so in the case of some books (see my PHP book for example), it will check .com hourly, but .fr and .ca would be daily, thus it will vary between domains even within the same book, as many books are popular only in specific regions.

But WHY?

Two big reasons:

  • Less frequent checks allow the system overall to be faster at loading pages and data (more improvements coming soon on this)
  • More capacity for NovelRank to support tracking a larger number of books and benefiting more authors going forward. Amazon has limits on the amount of data you can request per second, so there is a raw limit to what NovelRank can provide due to these restrictions by Amazon.

I want NovelRank to always be useful, fast, and benefit as many authors as possible, and this is just the first step in continuing to uphold these goals. This slow down for books that are not actively selling but actively being tracked will be gradual and be in full effect by April 6, 2011.

What about new books?

When a book is first added to NovelRank for salesrank tracking, its last sale date is set to the day the book was added, so it will immediately be treated to hourly sales rank checks for at least the next 7 days (more if it continues to sell books!).

Final Word

When I use the term books here, I am referring to any paperback, comic, hardcover, kindle, etc. format that is tracked on NovelRank. For simplicity I just refer to everything allowed on NovelRank for tracking as books. The FAQ has also been updated to reflect this change. Photo courtesy of digitalmums.

Sales Rank Myths Busted – What Effects Changes in SalesRank

Tuesday, January 4th, 2011

what does sales rank mean It’s time to put myths, legends, and mysteries to rest. Sales rank has been elusive for too long, so thanks to the support of NovelRank donations, I’ve conducted a series of tests to answer some long standing questions about this elusive beast we call, Amazon’s Sales Rank!

MYTH: Sales rank improves when a review is added.

Reality: False. Testing reviews, verified purchases as well as unverified reviews had no effect on a book’s sales rank. This is false for anything except actual sales which do effect sales rank.

MYTH: Sales Rank automatically returns to original value when a kindle book is returned.

Reality: False. This was tested by purchasing a Kindle book at 5:47am. at 8am, Amazon reflected the new sales rank. At 8:30am, customer support was contacted and the e-book was returned. Sales rank deteriorated normally and did not reset back to the original pre-sale value.

MYTH: Book purchases effect sales rank immediately.

Reality: False. There is a 3 hour delay between when a purchase is completed and when the sales rank is reflected by Amazon. This ensures that the order will not be canceled (they are fast). This is true for both Kindle and print purchases.

MYTH: Purchases that are affiliate driven (Amazon pays a percentage of the price to the affiliate referrer) do not effect sales rank.

Reality: False. There is no difference to Amazon between an affiliate sales and a sale driven by Amazon.com direct searches. To them, a sale is a sale is a sale is a… you get the idea.

MYTH: Purchasing multiple copies on a single order does not improve sales rank like purchases made on two separate orders.

Reality: True! To perform this test, I purchased three different books within a single order. One was a control (single copy), one had two copies purchased in a single order, and the last had a single copy purchased. After submitting that order, using the same Amazon account, 10 minutes later I purchased a second copy of the 3rd book (which had a single copy purchased in the first order). The results? After 3 hours, all 3 books moved from a rank of 1,020,000 (+/- 14,000) to a rank of 123,500 (+/- 500). After 1 additional hour, the 3rd book moved to a rank of 64,000, reflecting the second purchase order!

MYTH: A canceled order will cancel the sales rank effect.

Reality: True. Purchasing a copy of a print book and then canceling the order 20 minutes later (while still allowed by Amazon) will not trigger a change in sales rank.

Final Thoughts

I hope everyone enjoyed this insight. If you have any myths you’ve always wanted busted, put them in the comments below. This is one of those tests I wanted to do for a long time, so I’m glad to finally get this information into the hands of authors. Basically, increase sales, and if possible, have them all happen at the same time using separate orders on Amazon to ensure the largest effect on sales rank!

Finally, thanks for using NovelRank and thank you to the supporters whose donations made this possible!

Book Sales Rankings

Thursday, June 3rd, 2010

Pursuit of Honor book cover
I was recently asked what amount of book sales lead to rankings averaging 100, 1000, etc. Put another way, how many books would an author have to sell in a given month to have an average ranking for the month of 1000? So, I dug back into the book sales estimates and came up with 3 examples.

This is based on data on Amazon.com only. For Amazon.co.uk, you can roughly estimate that it takes only 80% of the number of sales on Amazon.com to equate to the same average ranking. For Canada, Germany, Japan, and France, it is approximately 65%, though there is not enough data in NovelRank to depend on that percentage.

Sales Rank Average: 1000 (paperback, hardcover, etc)

Example book: Pursuit of Honor by Vince Flynn
About 250 copies were sold to maintain a sales rank around 1000. That makes it 8 books per day, with a sale occurring every 3 hours, or maybe 2 books selling every 6 hours! Either way, this is a very healthy sales rank.

Sales Rank Average: 100 (paperback, hardcover, etc)

Example book: The Elegance of the Hedgehog by Muriel Barbery and Alison Anderson
Almost 2000 copies were sold in May to garner an average sales rank of 106. That is a selling rate of at least 3 books per hour! What is likely is that this number may actually be notably higher, as sales rank changes are less defined or varied at this level, however it is hard to verify.

Sales Rank Average: 2000 (Kindle Edition books)

Example book: In the Mood by Ellen Fisher
Selling approximately 500 kindle books a month will lead to an average sales rank around 2000 for your book. To do this, you need to sell about 16 books a day or 1 book every 90 minutes.

Note: This Kindle sales estimate is based upon real sales data from Amazon DTP provided to me from the author. NovelRank is currently underestimating for Kindle Edition books with a Sales Rank below 4000.

Hopefully this is enlightening for you. Remember, the strength of NovelRank is not in raw numbers; You will get those from your publisher eventually, but rather in understanding the fluctuations so you can attribute your best marketing efforts to the strongest sales bumps in near real-time.

Disclaimer: NovelRank book sales estimates are based on fluctuations of sales rank and thus there are many factors (another blog post coming soon) that can cause for more sales to occur than is estimated by NovelRank. These numbers are estimates.
