Google Ads has introduced auto end screens that add an interactive element to video ads by displaying a screen with product or service details right after the video finishes.
This automated feature is designed to encourage actions such as app installs or product purchases, making video ads more engaging.

Auto end screens are currently available for in-stream ads in mobile app install campaigns only, with plans to expand.
Also, Auto end screens enabled in Google Ads override manually added YouTube end screens.
Auto end screens are generated using information from your campaign, like app name, icon, price, and a direct install link. They appear by default after eligible video ads.
