Share secure signals with bidders (Beta)

Publishers can share secure signals on RTB requests through Authorized Buyers, Open Bidding, and SDK Bidding with the third-party bidders they choose. These signals can be created through a signal collection script or adapter provided by a bidder or secure signal provider whom the publisher chooses.

The publisher is ultimately responsible for what information is contained in their chosen signals. The signals must be obfuscated before being sent to Google.

Secure signals will only be shared at the publisher’s explicit instruction and only with bidders the publisher has allowed to receive the signals. At no point will information contained in the signals be visible or readable by Google or its platforms.

Obfuscated data examples: 

• Encrypting, hashing, or otherwise transforming data to a non-human readable format.
• Any information that doesn’t include a self-describing component and is not recognizable as PII or structured data.

Non obfuscated data examples: 

• PII in the clear. Examples: phone number, email address.
• Structured data that makes otherwise “non-plain text” information understandable. Examples: .json, .xml files that provides an explanation of the data it contains.

Secure signals are subject to the Google Ad Manager Partner Guidelines. When you turn on secure signals, you acknowledge that you've reviewed and accepted the Ads Data Processing Terms.

Select allowed secure signals

Complete the following steps to select the secure signals to share with bidders: ​​​

1. Sign in to Google Ad Manager.
2. Click Inventory, then Secure signals. A table shows the secure signals you can share. 
3. To share a secure signal, under "Enable app integration" or "Enable web integration," turn on the toggle .
4. For web integrations only, Google can deploy the signal collection script for you.
   Select Google deploy under "Signal collection deployment".
   Using this option only deploys the signal to your page from a location provided by the signal collector.
   If the signal collection script requires information or integration, work with your signal provider.
5. Alternatively, deploy the signal collection script for an existing Prebid UserID module ^(Beta) .
   Under "Signal collection deployment", select Prebid UserID module ^(Beta) .
6. Under "Secure signals settings," select Share to share secure signals on non-personalized (NPA) ad requests.
7. Click Save.

If you're using a Content Security Policy (CSP), ensure the signals you select are allowed by the publisher. Google will load the vendor script from a URL provided by the provider. If the script requires any further integration for its correct operation, it is the publisher's responsibility. You should contact the vendor for additional information.

If you select the "Publisher deploy" option, you must deploy the signal collection script on your own. You should also contact the signal provider(s) directly to understand additional requirements or if issues arise.

Web signal deploy option	Google actions	Publisher actions
Publisher deploy	None	Publisher is fully responsible: To load the vendor’s script.  For any integrations required for the script’s operation.
Google deploy	Google will load the script from a location shared by the provider.  Google does not: Validate the script in any way. Perform any additional integrations.	The publisher is responsible for any additional integrations required for the script’s operation.
Prebid UserID module	Google passes output of a Prebid UserID module(s) per configuration in the Ad Manager UI.	Prebid UserID module integration can be manually controlled by the publisher, or you can choose to automatically pass all Prebid UserID modules through secure signals. To use auto-configuration: Select Inventory, then Secure signals. Select the checkbox "Use your Prebid configuration to automatically configure your Secure signals settings". This overrides any manual configurations set in Ad Manager for the secure signals that are detected in the Prebid UserID module. When this toggle is turned on, you won't be able to use Ad Manager to individually control those secure signals.
