Ad Experience: Prestitial Ads with Countdown

Prestitial “Countdown” ads appear before the content of the page has loaded, forcing the user to wait a number of seconds before they can dismiss the ad, or the ad closes on its own.

These ads can disrupt users in a way that dissuades them from waiting for the countdown to finish and continuing onto their content.

In desktop environments, prestitial ads that can be dismissed immediately did not fall beneath the Better Ads Standard for desktop.
