In today’s post I will show you how to analyze a promotion’s
financial efficacy.
Given my lackadaisical approach to marketing my Seamus
McCree series of mystery/suspense/thrillers, you’d be hard-pressed to guess
that I earned an A in Marketing during my MBA studies. Knowing what to do and
understanding how to evaluate results are different skills than actually doing
the darn thing. While I deserve an A for analysis, I’d give myself a
gentlemen’s D for my actual marketing efforts.
Fortunately, that lack of marketing means I have near
perfect data to analyze a recent sales tactic I employed: providing free copies
of the Kindle version of book 1 of the series (Ant Farm).
My specifics:
I have so far published five books in the Seamus McCree
series. All are available in paperback, and I have assumed the Kindle promotion
had zero effect on paperback sales. I am currently, and have been for some time,
part of the KDP select. That means the only place you can buy an electronic
version of the books is on Amazon for a device that reads the Kindle format
(reader, computer, phone). All my books are enrolled in Kindle Unlimited (a
subscription service that allows readers to read unlimited pages each month for
a fixed price and pays the authors an amount per page of their works read).
While the calculations below are based on my Amazon-only
sales universe, the concepts are equally applicable to authors who have their
books available for wide distribution (Nook, Kobo, iBooks, etc.).
Step 1: Determine
baseline sales.
For me, this was relatively easy because I had done no
marketing during the two and a half months prior to the sales campaign. Count the
number of books sold (or better royalties paid) for the base period for each
book in the series and divide by the length of the base period (in my example
2.5 months).
If you sell wide, you can add together your sales for each
book or perform this step separately by venue. For those of us participating in
KDP select, we’ll need to collect the royalties for electronic books sold and the
Kindle Unlimited (include KOLL) pages read for each book in our series. Normalize
these results by converting everything to a per month basis. I assume Amazon
will pay an average of $0.045 per page read. That means I expect to earn $45
for every 10,000 pages read.
The reason I estimate revenue per KU page read is I am not
willing to wait the extra time for Amazon to let me know exactly what each
month’s actual payment rate will be. (It varies each month based on Amazon
whim—er secret formula.) If I wanted, I could redo the analysis once the final
figures are in.
These are your Base Level Results. If you did nothing else,
these are the revenues you would expect to generate from your series.
Step 2: Determine
Cost of Each Free Download
If you simply announce the giveaway on your social network
feeds and to your newsletter subscribers, you have no cost (unless you have
enough newsletter subscribers so you need to pay for that). I chose FreeBooksy
(owned by Written Word Media) to advertise my free download opportunity for Ant Farm and paid for a feature that
advertised that the giveaway was part of the Seamus McCree series. It cost
$142.50.
During the five-day promotion, Amazon indicated I had “sold”
5,915 books at the bargain price of $0.
The Cost per download is Cost of Promotion)/Number of
downloads. For this promotion that was $142.50/5915 = $.024.
Step 3: Determine the
Revenue earned per download:
Wait a minute; it’s cost me $0.024 per download, where’s the
revenue come from?
The great thing about series is that if people like the
first book in the series, even though it was free, some of them will buy the
second book in the series. If they like that, some will buy the third book in
the series. Etc.
The most read book in a series is almost always the first
book. Someone who discovers Sue Grafton’s Y
is for Yesterday, likes it and wants to read more, is likely to start at
the beginning with A is for Alibi.
The same for me: they read Empty Promises
and like it, they’ll go back to the first book, Ant Farm.
By giving away Ant
Farm, I hoped to earn revenue from sales (or KU pages read) of other books
in the series.
Because I haven’t run any other promotions on the Seamus
McCree series after the giveaway, I can determine how long the effect of the
sale lasted. For Kindle purchases, it was about 2.5 months. Interesting to me,
for Kindle Unlimited pages read, I’m experiencing a new, higher, “normal” level
after the promotion. Regardless of that continuing bump, I cut off the KU
effect at 2.5 months as well for purposes of this analysis.
For each book I determined royalties received and Kindle
Unlimited pages read during the 2.5 months following the promotion.
That’s not all extra revenue, If I hadn’t done anything, I’d
expect to continue to earn all the base revenues for each book. To get the
excess revenue for each book, I needed to subtract the 2.5 months of the
baseline from the actual sales.
I know lots of authors go cross-eyed looking at formulae. So,
using words: we take the average monthly revenue for a product after sale and
subtract the average monthly revenue for the same product before the sale to
get the effect of the sale. Then, if the effect lasts longer than a month (in
my case it lasted 2.5 months) multiply that result by the duration.
Here’s a simple example to see how this works. Say before
the sale I earned an average of $10 a month on Book 2. During the 2.5 months
after the sale, I earned (say) $60. My extra profit is the $60 less what I
would have expected to earn during that period ($10/mo. x 2.5 mos. = $25). The
extra revenue is $35 ($60 - $25).
Since I have five books in the series and I have both Kindle
sales and KU reads, my total profit on the promotion is the sum of the excess profit on Kindle
purchases and pages read under Kindle Unlimited for all five books.
An Aside about Kindle
Unlimited
My expectation was that by giving away Ant Farm, those possibly interested in reading it would download it
for free. Kindle Unlimited folks apparently have a different mindset. They
don’t need to “own” the book; they’re happy to read it and “return” it to the
Amazon library. During the 2.5 months following the giveaway, KU readers read
over 50,000 pages of Ant Farm, which
is the equivalent of almost 100 books for revenue of $225+. That group alone
more than paid for the advertising expense of $142.50.
Back to the Main
Analysis – Average Revenue per Download
Adding the extra revenue earned because of advertising and
giving away free Kindle copies of Ant
Farm from both Kindle sales and Kindle Unlimited reads totaled $1,023.60.
Dividing that by the number of downloads gives average revenue per download.
$1023.60/5915 = $0.173
Recall that each download cost $0.024. The profit per
download was $0.149. Yippee!
Takeaway #1
If we assume future readers will act in the same manner as
those who participated in the analyzed sale, my break-even point is 17.3 cents
per download. A quick analysis of whether a promotional website delivers value
to me suggests that if the cost per download is greater than 17.3 cents, I
should avoid it. How can you tell in advance? You can’t, but if something
doesn’t work for you, don’t repeat it in the hopes the second or third time is
the charm. Also, you can search for results other authors have shared in blogs
like this one.
Question: Can we
learn more from the data?
Of course. I wouldn’t have posed the question otherwise. It
was an unexpected bonus to discover many Kindle Unlimited readers preferred to
read Ant Farm through KU rather than
downloading for free. Those pages read paid for the advertisement (and more).
My original expectation of where I would make money from this promotion was
that enough people would like Ant Farm
well enough that after reading it they would buy the next in the series, Bad Policy.
And those who also like Bad
Policy would read Cabin Fever,
and so on down to Doubtful Relations
and Empty Promises. [Did you catch
the subtle use of the alphabet for the order of the series novels?]
That follow-through from one book in the series to another
is called “Conversion” in the trade.
Conversion
Good conversion, I thought, was the key to making money from
giving away the first book of a series. I figured I had a good chance of
converting people from Ant Farm to Bad Policy. Ant Farm has a 4.6 rating on Amazon (50+ reviews) and 4.35 rating
on Goodreads (100+ ratings).
Before I saw the results of the giveaway, I only considered
one kind of conversion: from giveaway to sales of books 2, 3, 4 & 5. I
discovered (others already knew this, but I hadn’t thought of it) that Kindle
Unlimited readers have a separate conversion from book 1 to 2 to 3, etc.
Here are my actual Kindle sales conversions during the 2.5
months following the Ant Farm
giveaway:

Conventional wisdom suggests that those who download free
books do not buy books at market prices (in my case $3.99). In fact, some
readers use free books as a no-risk way of checking out new-to-them authors. If
they like what they read, they’ll buy more. During the 2.5 months following the
free-giveaway, only .59% purchased Bad
Policy.
That seems dismal; but in fact, taking those people and
following them through the extra sales of the other three series books was
sufficient to make the advertising buy profitable.
There is a HUGE drop-off between those who acquired Ant Farm for free and those willing to
spend money to purchase Bad Policy.
Of those who went on to buy Bad Policy,
60% purchased Cabin Fever and if they
bought Cabin Fever they surely became
fans: 81% bought Doubtful Relations
and of those 88% bought Empty Promises.
As I thought, if I could get people to buy a book of the
series, a significant percentage would really enjoy the book and buy more. They
key is how many people actually read free downloads. That, I have no way of
determining, but enough did that their subsequent purchases more than covered
the advertising costs of the giveaway.
Takeaway #2:
Even though the only place to purchase electronic copies of
my novels is on Amazon, the giveaway was profitable. Those who could also give away
and sell in other markets would be even better off for ebook sales alone.
Conversion for Kindle
Unlimited Readers
For Kindle Unlimited, the percentages are a bit different:
Book From

|

|
106.90%

Cabin Fever
|
Doubtful Relations
|
87.58%
|
Doubtful Relations

75.37%
|
I speculate that the result of more than 100% for conversion
from Ant Farm to Bad Policy reflects a group of people who did download a free copy
of Ant Farm and then used Kindle
Unlimited to read Bad Policy. The
other percentages are consistent, except the conversion from Doubtful Relations to Empty Promises is lower for KU readers.
My guess is that this reflects non-binge readers. Some will pick up Empty Promises in the coming months.
In fact, while Kindle sales have stabilized at pre-giveaway
levels. Kindle Unlimited pages read are still more than twice pre-giveaway
levels.
Takeaway #3:
Kindle Unlimited readers changed what would have been a
modestly profitable advertising buy and book giveaway into a (relatively) huge
success.
Takeaway #4:
Although Bad Policy
is the second in the series, it was the first published. In my opinion it is
the weakest writing of any of my books. Ant
Farm, the intended first book, was not bought by a publisher until I
completely rewrote it after publishing Cabin
Fever. The 60% conversion from Bad
Policy to Cabin Fever might be
because of this weakness.
It also might be that the back-matter material in Bad Policy is not optimal for eliciting
readers to immediately purchase Cabin
Fever. I’ve recently changed it, and time will tell whether that will bump
up the conversion to Cabin Fever.
Anything I can do (other than rewriting the book) is worth money because the
conversion rates after Cabin Fever
are stellar.
Takeaway #5:
As expected, I earned the most money on sales and pages read
of Bad Policy. What surprised me
completely was that Ant Farm provided
the second largest profit, both from Kindle books sold and Kindle Unlimited
pages read.
This, I think, shows the power of Amazon lists and “also
reads.” People who did not know of the initial giveaway discovered the book
through the power of Amazon’s platform. This had everything to do with placing
high on Amazon’s best seller lists. During the giveaway, Ant Farm reached #22 in the overall Kindle Store for free books,
and #1 for free books for both Private investigators and Suspense within the
Mystery, Thriller & Suspense category.
Takeaway #6
The overwhelming effect of Kindle Unlimited for me is the
reason why I remain in the KDP select program and have not gone wide. Most
people who have their ebooks available on multiple platforms say they receive
anywhere from a rare low of 60% to a more typical 75-85% of their sales from
Kindle sales on Amazon.
By comparison, in this sale, I received only 49% of the
additional revenue from Kindle sales. The remaining 51% came from compensation
based on Kindle Unlimited pages read.
Your results will
vary.
You have a different series, different target audience,
Mercury may be in retrograde, a tweet could cause everyone to forget to look at
books for several days. You may be selling wide, whereas I am concentrated in
the Amazon universe. You may have great international sales (mine are miniscule).
The point is, to figure out if your promotions work, you must
do this kind of analysis. Now you know how. Questions?
