We brought in a new photo of the Wikimedia Foundation staff and saw that we were able to increase donations by using a group photo displaying horizontally across the banner rather than a photo of the group on just one side of the banner.
Once we saw this new photo performed well, we tried a couple different sizes. The close up photo that takes up more of the banner had a higher click and donation rate. In our next testing day, we're aiming to try out a new banner with photos of five people who have written appeals. More info on that test to come in the next couple days.
