- Viewed certain videos

- Viewed certain videos (as ads)
- Subscribed to a channel
- Visited a channel homepage

- Added any video from a channel to a playlist
You can use these lists in your targeting settings for new or existing campaigns.

From the 'Audience manager' page, click the plus button and select + YouTube users to add lists. Then enter all the necessary information.
List sizes
For 'Initial list size', you can either pull list members from the last 30 days of activity on your channel, or start fresh.
