Third-party measurement on YouTube

Google does not accept third-party tracking pixels for YouTube measurement. Display & Video 360 supports third-party Viewability, Brand Safety, Reach & Brand Lift measurement for YouTube ads with verified measurement vendors. If you want to use a third-party measurement vendor (for example, Nielsen) for your YouTube ads, you'll need to enable this directly within Display & Video 360. Failure to do so is subject to disruptions to third-party measurement.

To enable third-party measurement for YouTube & partners line items, measurement partners must first be enabled in Advertiser settings. You will need a vendor client ID for each measurement partner, which should be provided by the measurement partner. 

Once the third-party measurement vendor is enabled for your advertiser, you can enable it on individual YouTube & partner line items. Optionally, you can request that a measurement partner is on-by-default, which will automatically enable the measurement partner for all newly created YouTube & partners line items

1. Configure third-party measurement for your advertiser:
   1. Navigate to Advertiser Settings > Basic Details > Additional settings > Third-party services and click the pencil icon to edit.
   2. Select the desired measurement vendors and enter the vendor client ID for each. 
   3. Click Apply.
2. (Optional) Request on-by-default enablement for a specific measurement partner by contacting support directly through chat or email. 

On-by-default enablement is only available for some Viewability, Brand Safety, and Reach measurement vendors. Reach out to your measurement partner contact to confirm they support on-by-default enablement and for information on the terms & conditions of using on-by-default settings.

3. Enable third-party measurement for individual YouTube & partner line items:
   1. Navigate to Line item details > Additional settings > Third-party vendors.
   2. Select a vendor for viewability, brand safety, brand lift, or reach. You can also add the optional reporting ID, or deselect measurement vendors if necessary.

Considerations

• Only one vendor-measurement-VCID (vendor client ID) combination is allowed per account.
• If any changes to the vendor client ID are needed, you must update this for the third-party vendor in Advertiser settings. 
  VCID updates will not affect existing line items, unless those line items are edited. Example: You can make and save a small change to an existing line item (and revert it if necessary) to ensure that existing line item uses the newest vendor client ID.
• For measurement partners enabled for on-by-default at the advertiser level, these settings will automatically populate for newly created line items, with the option to add a reporting ID or disable the vendor on individual YouTube & partner line items.
• Third-party measurement for YouTube Programmatic Guaranteed deals must be configured by your account manager. Reach out to your account manager for more details. Third-party measurement for Instant Reserve deals can be enabled within Display & Video 360 during deal creation or editing.
• Third-party measurement support is limited for YouTube & partners line items using multi-format ads, including video views and efficient reach subtypes. Reach out to your measurement partner contact for more information.
• Not all third-party measurement vendors are supported for all YouTube ad formats.
