Hi all,
Here is the usual look
<https://www.mediawiki.org/wiki/Reading/Readership_metrics_reports> at our
most important readership metrics. This time we see an overall rise in
pageviews following the seasonal winter slump, examine the recent
year-over-year growth in pageviews more closely, and introduce a new day-7
retention metric for the Wikipedia iOS app.
As laid out earlier
<https://lists.wikimedia.org/pipermail/mobile-l/2015-September/009773.html>,
the main purpose is to raise awareness about how these are developing, call
out the impact of any unusual events, and facilitate thinking about core
metrics in general. As always; feedback and discussion welcome.
Week-over-week and month-over-month changes are being recorded on the
Product page <https://www.mediawiki.org/wiki/Wikimedia_Product#Reading> at
MediaWiki.org. This edition of the report covers a timespan of five weeks.
You can also find lots of other traffic and usage data in the quarterly
metrics presentation
<https://commons.wikimedia.org/wiki/File:Wikimedia_Foundation_Reading_metrics_Q2_2016-17_(Oct-Dec_2016).pdf>
for Q2 2016-2017 (October - December) that was just published by the WMF
Reading team.
All numbers below are averages for January 2 - February 5, 2017 unless
otherwise noted.
Pageviews
Total: 582 million/day (+10.14% from the previous report)
Context (April 2015-February 2017):
See also the Vital Signs dashboard
<https://analytics.wikimedia.org/dashboards/vital-signs/#projects=all/metrics=Pageviews>
After the seasonal winter slump, we see a rise in desktop pageviews, as
expected. Mobile pageviews continue to remain at higher levels than before
christmas. The previously mentioned iOS app’s pageview increase is still
under investigation, and may turn out to be an anomaly
<https://phabricator.wikimedia.org/T154735> inflating mobile pageviews by
roughly 5 million views per day.
This chart looks at long-term traffic trends from May 2013 - January 2017.
This shows that over this timespan, the annual change in overall pageviews
was -2%, desktop has been down 15%, and mobile (web + apps) has been
trending upwards at a rate of 23% per year. However, the past few months
have seen total pageviews increasing year-over-year (chart further below).
To facilitate our understanding of which traffic movements are seasonal and
which may indicate lasting changes, here is a chart overlaying the total
pageview numbers back to May 2013 (the earliest time for which we have data
according to the current pageview definition):
Total pageviews have continued rising and are now higher than before the
winter holidays. The blue line shows that the increase in overall pageviews
year-over-year remains (January 2017 is up 5% from January 2016). It is
possible that a smaller part of this is due to unidentified bot traffic
(e.g. we just updated <https://phabricator.wikimedia.org/T157528> the
pageview definition to exclude a recently discovered bot that had been
causing up to 0.9% of total pageviews). But overall it is starting to look
like a small but sustained rise in real human pageviews.
Here we see that the changed trend in recent months can be attributed to
desktop pageviews, which have mostly stopped declining year-over-year. This
chart also shows that the seasonal christmas dip in pageviews comes
predominantly from desktop views. Most recently, January 2017 desktop
pageviews are again down 1.8% from January 2016, but that is still much
less than the aforementioned -15% yearly trend since 2013.
Year-over-year mobile pageviews are still increasing at a notable rate, but
slower than in 2013-15. January 2017 mobile pageviews are up 13% from
January 2016, less than the yearly mobile growth of 23% in the overall
2013-17 timespan. We can see how mobile pageviews always increase around
the winter holidays and maintain higher levels afterwards.
Desktop: 50.9% (previous report: 51.5%)
Mobile web: 46.7% (previous report: 46.8%)
Apps: 2.4% (previous report: 1.7%)
Mobile percentage dropped a bit following the christmas spike, but remains
high at an average of 49% mobile views. The previously mentioned iOS app’s
pageview increase is still under investigation, and may turn out to be an
anomaly <https://phabricator.wikimedia.org/T154735> inflating this metric
by about 1%.
Global North ratio: 77.3% of total pageviews (previous report: 76.8%)
Context (January 2016-February 2017):
Although Global North pageview percentage fell following the winter spike,
but overall this metric grew since the last report. Levels remain in the
high 70 percentile range.
NB: We are currently rethinking this metric and might replace it with a
different country selection constructed as part of the work on the New
Readers project
Unique devices
See the announcement blog post
<https://blog.wikimedia.org/2016/03/30/unique-devices-dataset/> from March
2016 for background and details on this metric. These estimated numbers are
provided for all Wikimedia language projects (separately for the desktop
and mobile web version). Because of the instrumentation method, there is no
global metric for all projects and all languages, but it is currently being
extended <https://phabricator.wikimedia.org/T138027> to a cross-language
global metric per project at least. For now, we track the daily numbers of
English Wikipedia in this report.
Daily unique devices estimate for English Wikipedia:
-
Mobile web: 36.3 million
-
Desktop: 24.3 million
-
Total: 60.6 million
-
Average mobile web ratio: 60.0%
Context (January 2016- February 2017):
Since the last report, both daily unique desktop devices and mobile devices
grew. Mobile web daily uniques mirrors the daily pageviews chart - mobile
web unique levels have remained higher than before the winter bump.
January 2017 was the first month we could compare year-over-year changes in
unique devices. While pageviews on English Wikipedia are up from January
2016, the number of monthly unique devices is down 16%. For this report
timespan (Jan 2 - Feb 5), daily mobile web uniques are up 2.6%, while daily
desktop uniques are down 8.2%. This is currently being investigated.
While the number of daily unique desktop devices has grown overall, the
ratio of pageviews to devices on desktop has steadily declined back to pre
christmas levels. The small, but notable increase in daily views per device
for mobile web which happened in November has held up.
New app installations
Android: 18.0k/day (-5.9% from the previous report)
Daily installs per device, from Google Play
Context (last nine months):
The number of daily installs dropped after the christmas spike, but remains
higher than the number of uninstalls (except for January 26). Overall, the
number of daily installs has dropped nearly 6% and daily uninstalls dropped
about 8% since the last report.
iOS: 5.67k/day (+6.5% from the previous report)
Download numbers from App Annie
Context (last two months):
[image: Wikipedia iOS app daily downloads by country, Dec 6, 2016 - Feb 5,
2017 (App Annie).png]
Similar to other mobile metrics measured in this report, the iOS app
download metric has remained higher than usual following the winter bump.
During the timespan of this report, iOS app downloads remain fairly steady
besides two large, unusual spikes at the end of January in the United Arab
Emirates and the United States (which follow the spike from the Netherlands
in December) which are likely anomalies. We are looking into filing a bug
report with App Annie to investigate this.
App user retention
Android: 15.6% (previous report: 16.8%)
(Ratio of app installs opened again 7 days after installation for all dates
that fall within this report. 1:100 sample)
Context (last six months):
As remarked in earlier reports, this data is a bit too noisy for drawing
conclusions about whether retention changed significantly between different
releases. However, we can at least rule out the existence of major shifts
during this timespan. There was a small spike in day 7 retention for
installs on January 22nd.
iOS: 19.2% (previous report: N/A <https://phabricator.wikimedia.org/T126693>
)
(Ratio of app installs opened again 7 days after installation for all dates
that fall within this report. 100:100 sample since iOS app only sends data
when users opt-in so there is a small user base)
Context (last two months):
After a long break where we refrained from reporting iOS retention here due
to data quality issues with the number provided by Apple, we are happy to
report iOS app 7 day retention again, based on a new EventLogging
instrumentation that parallels the one on Android. There doesn’t seem to
have been any significant changes in retention levels during the timespan
of this report, even after new releases of the app. Looking back at
December though, it appears that there was a period of lower retention
which roughly corresponds with stability issues (crashes) the app was
having at this time, and which have since been fixed.
Unique app users
Android: 1.211 million / day (+2.7% from the previous report)
Context (last eight months):
Android daily average levels have remained higher following the christmas
and new year’s bump. This matches the mobile pageviews and unique mobile
devices metrics.
iOS: N/A <https://phabricator.wikimedia.org/T130432>
