From October to November 2017 and December 2017 to February 2018, we ran two A/B tests to gauge the performance of the feature prior to release on these projects. The results, described in more detail in the report, displayed a decrease in pageviews, but an overall increase in the number of pages readers interact with, indicating that they are more likely to explore a larger variety of topics when the feature is on. We also noted decreased usage of the back button and very low rates of disabling the feature. In addition, we ran a number of fundraising tests on enwiki.
