Which of these can be created to run on the Display Network?
- VideoPlus ads
- TrueView and VideoPlus ads
- Homepage expandable Masthead ads
- Lightbox ads and TrueView in-display ads
Explanations:
Discovery and lightbox ads both appear on the Display Network. Lightbox ads responsively combine your ad assets — like videos, image galleries, and maps — to fill available ad spaces. Lightbox ads may contain multiple videos, image galleries, or combinations of these.
Lightbox ads are expandable, rich media display ads that run across the Google Display Network. https://support.google.com/adwordspolicy/answer/6135143
Video discovery ads appear in places where viewers discover content, like on YouTube search results, next to related videos, on the YouTube homepage, and on partner sites and apps.
