Hi all,

here is the weekly look at our most important readership metrics, a bit belatedly this time.

As laid out earlier, the main purpose is to raise awareness about how these are developing, call out the impact of any unusual events in the preceding week, and facilitate thinking about core metrics in general. We are still iterating on the presentation and eventually want to create dashboards for those which are not already available in that form already. Feedback and discussion welcome.

For readers of this report who haven’t already seen it, I’d like to mention the exciting announcement of the new pageview API for per-article readership metrics.

Now to the usual data. (All numbers below are averages for November 9-15, 2015 unless otherwise noted.)

Pageviews

Total: 540 million/day (+0.7% from the previous week)

Context (April 2015-November 2015):

(see also the Vital Signs dashboard)

Some may remember that back in September, this weekly report called out a “conspicuous 4.3% drop” in total pageviews during the week until Sept 20 (followed by another 0.7% decrease the following week). Well, last week the Analytics team solved that mystery: An improvement in detection of web crawlers had caused much more pageviews to be classified as non-human, from Sept 16 on (e.g. for Commons, estimated human traffic dropped from about 12 million to about 4 million per day).

Desktop: 57.5% (previous week: ​57.5%)

Mobile web: 41.3% (previous week: ​41.3%)

Apps: 1.2% (previous week: ​1.2%)

Global North ratio: 77.6% of total pageviews (previous week: 77.5%)

Context (April 2015-November 2015):

New app installations

Android: 55.3k/day (-8.8% from the previous week)

Daily installs per device, from Google Play

Context (last month):

As already mentioned in last week’s report, the Android Wikipedia app got featured in the "New and Updated Apps" section of the Google Play store on November 5, enabled by the Android team’s recent update work and facilitated by the Partnerships team. The promotion lasted one week and we can now see that it was a huge success (with the effect on download numbers  much more clearly discernible than in the case of the “Back to School” feature we discussed last month). Predictably, uninstalls went up slightly too, but most of the new users kept the app on their phone. What is a little concerning though is that after the promotion, install numbers fell below the previous baseline, with the install base even shrinking a tiny bit right afterwards. (One possibility is that we are seeing some sort of depletion effect, due to people who would have installed the app anyway around this time, but saw it earlier due to the promotion.) For that reason, we will wait a bit longer before estimating the overall impact of this promotion.

iOS: 4.59k/day (+4.3% from the previous week)

Download numbers from App Annie

Context (last 12 months):

No big news here - things are back to normal after the App Store feature last month.

App user retention

Android: 15.2% (previous week: 13.9%)

(Ratio of app installs opened again 7 days after installation, among all installed during the previous week. 1:100 sample)

Context (last three months):

Recall that this metric lags one week behind, so to speak. I.e. the effects of the Play Store promotion are not fully visible yet above (spoiler though, having looked at a few more days of data already: retention for installs who had come in during the promotion does not appear to have been lower than usual, which is good news).

In general, this data is quite noisy due to the low (1:100) sample rate.

iOS: N/A

(Ratio of app installs opened again 7 days after installation, among all installed during the previous week. From iTunes Connect, opt-in only = ca. 20-30% of all users)

Unfortunately I encountered some data quality issues with this metric this week. Will investigate, and report iOS retention again once this is sorted out. (The numbers and charts provided in the iTunes Connect App Analytics appears to have changed quite a bit retroactively.)

Unique app users

Android: 1.217 million / day  (+2.7% from the previous week)

Context (last three months):

A somewhat noticeable rise that could well be connected with the aforementioned Play Store promotion, but still needs a closer look once more data is in.

iOS: 281k / day (+0.2% from the previous week)

Context (last three months):

No news here.
