How it works
Your data segments are created by first linking your YouTube channel to your Google Ads account. Once you link accounts, you can reach people who have done the following YouTube-related actions:
- Viewed any video from a channel
- Viewed certain videos (includes both organic and ad views)
- Viewed any video (as an ad) from a channel
- Subscribed to a channel
- Visited a channel homepage
- Liked any video from a channel
- Added any video from a channel to a playlist
You can use these lists in your targeting settings for new or existing campaigns.
To manage your lists, click the Tools icon 
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.
Bear in mind that Google Ads doesn’t use your data segments to populate new memberships for YouTube channel and YouTube Masthead in ads on non-Google websites. As a result, any reporting for the YouTube channel and YouTube Masthead data segments will show as '0' under 'Size: Display' on the 'Audience insights' page in Google Ads.
