Ads can't mimic YouTube site elements in any way, shape or form. The following are not allowed (this list is not exhaustive):
- Ads should not resemble or try to resemble part of the YouTube homepage site experience.
- Ads should not deliver or seem to deliver messages that are meant to look like they originate from YouTube.
- Ads during streams (also known as in-stream video ads), including TrueView, should not mimic the Skip Ads button.
- Any YouTube thumbnails in an ad need to allow viewers to click and watch a video within the masthead or on the YouTube watch page. For example, a few seconds of animation of thumbnails being destroyed doesn't give viewers an opportunity to click and watch the videos. Also, any metadata associated with video thumbnails must be accurate.
