Third-party measurement on YouTube

1. Third-party measurement account configuration for Google Ads at account-level

Before you can enable measurement for third-party viewability, brand safety, brand lift, and reach on YouTube campaigns in Google Ads, you need to have the vendor client ID for each measurement type that you plan to use on your account. The third-party measurement vendor can provide you with the vendor client ID.

As of December 2023, advertisers can self-enable account-level third-party measurement partners via their corresponding vendor client IDs. Follow these self enablement instructions in Google Ads:

1. In your Google Ads account, click the Admin icon .
2. Click Account settings.
3. Click the Third-party measurement section.
4. Select Add vendor.
5. Select the measurement type that you want to measure and the third-party measurement vendor.
6. Add the vendor client ID from the vendor. Vendor ID should be provided to you by your measurement partner, reach out to your respective measurement partner if you don’t have one.
7. Click Save.
8. (Optional) Request on-by-default enablement for a specific measurement partner (only available for limited vendors) by submitting a request through this form. Ensure you have client approval & vendor alignment to enable on-by-default as support will request this confirmation from you.

After you add vendors at the account level, they’ll become available to use at the campaign level.

To have the same vendor and vendor client ID automatically selected for new campaigns, contact Google support. You can deselect it anytime in your campaign settings.

2. Third-party measurement configuration for Google Ads at campaign-level

You can self enable each campaign and input the vendor reporting ID (if applicable). Follow these self enablement instructions in Google Ads:

1. In your Google Ads account, click the Campaigns icon.
2. Click the Campaigns drop down in the section menu.
3. Click Campaigns.
4. Below the "Campaigns" page header, you'll find 3 tabs. Click the Settings tab.
5. In the table, click the campaign that you'd like to enable.
6. On the "Settings" page, click Additional settings.
7. Expand the “Third-party measurement” panel.
8. Select Add vendor.
9. Choose the metric type that you want to measure and the third-party measurement vendor.
10. Add the reporting ID from the vendor. This is required for all reach and brand lift measurement on all campaigns, unless otherwise instructed by your measurement vendor.
11. To add more measurement types, select Add vendor. If you need to remove a vendor, select the X next to each vendor.
12. Click Save.

Keep in mind:

• Only one vendor-measurement-VCID (vendor client ID) combination is allowed per account.
• The vendor client ID provided during account enablement will pre-populate for campaigns created after the configuration is saved when you select a given vendor’s measurement services during account configuration. You must file another account configuration ticket if there are any changes to vendor client ID, and this update must also be made at the line item level by self enablement.
• For measurement partners enabled for on-by-default at the advertiser level, these settings will automatically populate in the line item settings with the option to add a reporting ID or remove these settings.
