- YouTube users lists: Create remarketing lists of viewers based on their past interactions with your videos, YouTube ads, or YouTube channel.
- Customer Match lists: Upload a data file of customers that are important to your business to use with Customer Match.
- Lookalike audience lists: Provide seed lists using your first-party data, including a customer match list or a list of people who’ve interacted with your website and app, or YouTube channel.

After you set up these lists, you can use them in your targeting settings for new or existing YouTube & partners line items. Learn more about targeting in YouTube & partners line items.
Third-party audience targeting and YouTube & partners line items
YouTube & partners line items only support first-party audiences that meet the Personalized advertising policy. Third-party audiences are not supported.
YouTube users lists
You can show personalized ads to millions of viewers across YouTube based on their past interactions with your videos or YouTube channel. Once you've linked a YouTube channel to your advertiser in Display & Video 360, you can create YouTube users lists for remarketing purposes.
You can generate YouTube users lists that include viewers who have done one of the following actions:
- Viewed any video from a channel
- Visited a channel page
- Viewed any video (as an ad) from a channel
- Liked any video from a channel
- Commented on any video from a channel
- Shared any video from a channel
- Subscribed to a channel
- Added any video from a channel to a playlist
- Viewed certain videos
- Viewed certain videos (as ads)
You can't build YouTube users lists off of views to bumper ads or non-skippable ads.
Create a YouTube user audience list
- If you haven't already, link your YouTube channel to your Display & Video 360 advertiser.
- In your Display & Video 360 advertiser, go to Audiences in the left menu, then select All audiences.
- Click New Audience and choose YouTube users.
- Enter a name for your audience and set the Membership duration.
- Choose a List type and a Channel.
- Fill out the rest of the form.
- Click Save.
You’ll see your created list in the All Audiences menu. When your YouTube users list has gained interactions from at least 1,000 viewers, you can use it for targeting.
Troubleshoot an empty or small YouTube users list
- Review the membership duration of your remarketing list
- The membership duration determines how long a user remains on the remarketing list. A membership duration too short may remove some or all existing members on a list.
- Check the video length
- If the remarketing list is built from videos "viewed as ads", check the length of the videos. A video shorter than 11 seconds won't collect any remarketing users when viewed as an ad, unless it’s uploaded as YouTube Shorts. This includes all Bumper ads, which won't increment any remarketing list users.
- YouTube Shorts are eligible for remarketing list membership collection if they are viewed for at least 10 seconds or the full length of the Shorts video, if the total length is less than 10 seconds, along with clicks.
- Confirm the video audiences is not "Made for Kids"
- We don’t serve personalized ads on kids content, as required by the Children’s Online Privacy Protection Act (COPPA) and/or other applicable laws. Learn more about What happens when your content is set as Made for Kids.
- Confirm the videos used in the remarketing list had views on YouTube
- We are limited in the memberships we can build for YouTube user lists when your videos or video ads are shown in third party sites and apps.
Customer Match audience lists
Customer Match lets you show ads to your customers based on data about those customers that you share with Google. With Customer Match targeting, you can also reach new users on YouTube by targeting similar audiences to your most valuable customers.
Upload a Customer Match data file

- Click New Audience and choose Customer match.
- Enter a name for your list and an optional description.
- Select a Data type from the drop-down list:

Note: For connected TV (CTV), select Mobile Device IDs from the drop-down list, then choose a mobile app platform and browse for your specific app name. You can only select one app per list upload.
- Upload a file by dropping a file or by clicking Browse.
Basic formatting guidelines
- Your data must be in a CSV file. Use a template or create your own file using a combination of the following header names in English: "Email", "Phone", "First Name", "Last Name", "Country", and "Zip".
- If you’re uploading mobile device IDs, it must be a separate file with “Mobile Device ID” as the only header.
- To keep your data secure, you can hash your customer data yourself using the SHA256 algorithm.
- Note that hashed mobile device IDs are not supported.
- Minimum number of entries/rows: 100 30-day active users.
- Maximum CSV file size: 5 GB
- Minimum user threshold: Display and Gmail = 100, Search and YouTube = 100
Column formatting guidelines
- Email address matching: Use “Email” as the column header name in your data file.
- Phone matching: Use “Phone” as the column header name in your data file.
- Mailing address matching: For mail address matching, your data file must contain these 4 column headers: “First Name,” “Last Name,” “Country,” and “Zip.” If any of the required column header names are missing, your upload will likely result in an error.
- Combined email address, mailing address, and phone matching: Your file must contain these 6 column headers: “Email,” “Phone,” “First Name,” “Last Name,” “Country,” and “Zip." If you have multiple email addresses, mailing addresses, or phone numbers for a single customer, your file may include multiple “Email,” “Zip,” or “Phone” columns.
- Mobile Device ID matching: Use "Mobile Device ID" as the only column header in your data file.
Formatting guidelines for uploading unhashed data
If you upload a list of contact information in plain text, Display & Video 360 will hash them using the industry-standard SHA256 algorithm. Hashing takes into account capitalization and spaces, so you'll need to make all characters in each entry lowercase and remove any extra spaces before or after each entry.Email - Include a domain name for all email addresses (for example, gmail.com or hotmail.co.jp)

- For United States:
- 5 digit codes are allowed
- 5 digits followed by 4-digit extension are also allowed and may improve your match rate
