Jakub Tested Pattern #83: Progressive Fields
In this experiment, we tested a visible "Shipping Frequency" (A) option against a progressively displayed one (B) that would only appear after someone first chose a duration option. Thus in variation B, the buy box component would initially appear with fewer fields and smaller. The experiment measured initial progression and actual sales.
Note on the data: the experiment was run a little shorter than usual, as one of the variations triggered a stop rule to protect losses (so the effect might be somewhat inflated from a lower power).

Jakub Tested Pattern #57: Maybe Later On Goodui.org
In this experiment, we tested a standard modal (with 2 choices) against a "Maybe Later" one (with 3 choices). One of the choices in the variant allowed users to postpone their decision with a "maybe" which would enable a floating bar at the bottom of the screen. Clicking on any of the "Yes" options would send people to the bottom of the screen with an email signup form. Increasing signup was our primary measure. Both modals also appeared instantly after a page load.
