The Unknown Reader…
3
Despite the digital
transformation of the
publishing industry,
authors & publisher
still cannot measure
reader engagement!
Do consumers read
the books they buy?

It doesn‘t really matter, does it?
4
If readers buy and pay
for books (revenue)
does it matter if they
read them or not
(engagement)?
Ah, but are publishers
selling paper or are they
offering entertainment
and education?©Frederic Bordoni

Part II
How to Collect Reading Data?

Online Content = Web Analytics
6
• Google Analytics
• Kissmetrics
• Mixpanel
• Optimizely
• Adobe Site Catalyst
• Flurry Analytics
Use of log files
(Server), tracking
pixels und Javascript
tags for the collection
of data.

What is an E-Book?
• An E-Book is 90% HTML = “web page”
• Reading application (iBooks, Kindle) = “Browser”
But, but, but:
• server log files = Amazon, Apple, Google, etc.
And content is processed/read offline
• application logs = Apple, Amazon etc.

8
Amazon, Apple & Google collect
vast amounts of reading app/device data,
but don‘t share this with publishers.

=
HTML 5 + CSS 3 + JS
A key feature of ePub 3 is the support for Javascript,
as well as HTML5 support for offline storage of data.

... and the data connection?
Engage readers!
When the reader clicks on a
link at end of chapter/book
(styled as a button), a data
connection with Jellybooks is
established = user opt-in

Readers use familiar Apps
Test reader are recruited based on whether they
already used one of the apps supported by JBKS

of the modification via
identifiers like “candy stripe”

B
A lot of “flipping” (jumping between
chapters), which is typical of book titles
readers find “have to read” but that
don’t hold their attention…
Rapid decline of reader
engagement in first 100
pages

Completion Rate
• Does the book keep
reader’s attention?
• Rate is measured as
percentage relative to
those who start reading
• Unlike ratings
(subjective), this is an
observational KPI
