CHECK IN TEAM/DEPT PROGRAM

Metrics highlights● This quarter, the year-over-year decrease in total pageviews accelerated,

due to both mobile and desktop. Apparent causes include the rollout of the page previews feature and a decline in Google referrals.

● New installs/downloads were down year-over-year for both apps.● iOS app users started to spend considerably more time per session in Q2.● Maplink and mapframe prevalence increased since last quarter.

○ Tajik Wikipedia had a 521% increase in mapframe prevalence.○ Finnish Wikivoyage had a 102% increase in maplink prevalence.

● Autocomplete is the dominant mode for search on Wikipedia. It is most dominant in languages with more articles and less so in languages with fewer articles, such as Bengali.

Long-term trendsGlobally, total readership has been slightly declining since 2013 (-2.6% yearly, largely attributable to several one-time effects. Around October 2016, the year-over-year change turned into growth again (+3.9% YoY in Q3), but this has reversed in the last two quarters (-2.2% in Q1, -5.2% in Q2). See below for some apparent causes.

Long-term, mobile has been increasing (+19.4% yearly since 2013) as desktop has been declining (-13.9% yearly since 2013).

Corrected for anomalous IE7 traffic from some countries and several other artifacts.

We had observed a positive year-over-year trend from October 2016 to March 2017, but more recently - particularly since August - this turned negative again, even more so since around November.Trend chart includes corrections for some anomalie, e.g. artifical IE7 traffic from Pakistan and some other countries.

Desktop is shrinking y-o-y again, and a bit faster since around August.

That month, we completed the rollout of “page previews” to all Wikipedias except de and en. This new feature is designed to save readers some clicks, so a decrease (2%-4% per A/B tests on de and en) is expected and to some extent desired.

On the other hand, mobile growth slowed too - see how blue and red appear closer together since about November.

Note the annual “Christmas bumps.”

(As a desktop-only feature, page previews don’t affect mobile.)

There appears to have been a slight year-over-year decrease in pageviews referred from Google since around November (stronger in December, but less of a difference again in January).

So far we have not been systematically monitoring the search traffic data provided by Google. We recently started work on storing it for further analysis, and also, some weeks ago Google rolled out a new beta feature allowing access to data 16 months back, enabling direct year-over-year comparisons:

Despite a (according to Google Play) shrinking install base, the app’s pageviews are up year-over-year, largely due to a (still unexplained) rise coinciding with the release of v190 at the end of February, and the usual “christmas bumps”.

Readers (core metrics)Feb 2018 Appendix: Android

In late September and early October, an apparently unintentional change in Google’s web search temporarily linked the app in many Wikipedia search results, resulting in a spike in installs (but not, remarkably, uninstalls). However, the install base (active devices) still continued to shrink during this quarter, from 7.54 million to 7.32 million.

NB: installs - uninstalls != change in install base (can also be caused by devices going inactive)

Remarkably, the many additional installers brought in by the Google snafu in late September and early October did not differ much in retention from those coming in via our usual channels (store search, mainly).

The usual “christmas bump” appears to have brought a lasting increase in traffic of several percent.

Apple named our app an Editor’s Choice on October 27, which appears to have brought an at least temporary increase in downloads. Still, total download numbers were down 7.5% year-over-year in Q2.
