Extension:Popups/Fundraising test 2

The Fundraising and Reading teams ran an experiment to see if Hovercards had an effect on fundraising.

Methodology
We selected the Hungarian Wikipedia for the first experiment, since there was already fundraising planned in Hungary in June/July, and it is a mid-sized Wikipedia where the community were receptive to a test.

Hovercards were enabled on the Hungarian Wikipedia for 50% of users on June 7. On June 15 the fundraising team began running banners in Hungary, with their usual campaign setup:


 * anonymous users only
 * users see one large banner (example) on their first visit to the site, and then smaller banners (example) on subsequent visits
 * two weeks after launch (29 June) the number of banners a user will see is limited to a maximum of 3
 * four weeks after launch (13 July) the campaign ends and banners are disabled
