In this mobile experiment, the A version contained two sticky/floating elements: the top navigation with a logo, and the bottom CTA. The variation only floated the bottom CTA, while the top logo var was using a default "static" position (disappearing on scroll like all other elements).

Impact on leads started and compelted was measured.

In this experiment, the height of a sticky call to action was decreased on mobile devices. To accomplish this change, a text phone number was also turned into an icon and its position was shifted. For extra context, the landing page also displayed numerous tiles, each with their own and repeated calls to action. Impact on leads was measured.
