The mobile exit intent pop-up embed method looks just like the regular pop-up method, but instead of automatically displaying the pop-up ad on content load, it loads the ad when the user scrolls up on their smartphone screen.
To set this up, simply create your placement and ad as normal, and then select the desired embed method from the drop down menu labeled “Embed Method Types”. This menu is located in the “Get HTML Tag” screen.
You can set the "Scroll Speed" within the creative tag. You also have the option to "Allow on Desktop" by just checking the box found.
