User:CKoerner (WMF)/Page Previews A/B test

Hello,

Page Previews (aka Hovercards) is currently the most popular beta feature on all desktop projects. It provides a preview of an article upon hovering over a wiki link for users interested in gaining more context on a subject.

Over the past year, we have been improving our code and incorporating community feedback in the changes to the design and functionality of the feature. Currently, the feature is rolled out on all Wikipedias, except for English and German. Before proceeding with rollout discussions on these two wikis, we would like to schedule an A/B test of the feature to ensure that we can replicate the positive quantitative results from other wikis on this Wikipedia.

The test will be three weeks in length starting August 14. During the test, 1% of anonymous users would receive the feature by default. We will compare their usage to a control group of 1% of anonymous users who do not have the feature enabled. For logged-in users, no changes in functionality will be expected.

Please, let us know if you have any comments or concerns on the test. Thank you!
