About secure signals

Secure signals is a processor feature required by bidding ad sources that use a third-party SDK. If your bidding ad source requires secure signals, you’ll be required to accept the Ads Data Processing Termsand accept that secure signals is a processor feature for your AdMob account.

You only need to accept these terms once in an AdMob account. If you’ve never used bidding before, you’ll be prompted to accept the terms when you set up a bidding ad source that requires secure signals. 

Secure signals for non-personalized ads 

You can choose whether you want to share secure signals with a bidding ad source on non-personalized ad requests.

When you turn on secure signals for non-personalized ads, secure signals are shared on both personalized and non-personalized ad requests for the selected bidding ad source. 

When you turn off secure signals for non-personalized ads, secure signals are shared on personalized ad requests only. Turning off secure signals for non-personalized ads may result in lower revenue from ad sources.

By default, the secure signals for non-personalized ads is automatically turned on for the bidding ad sources that require secure signals.

1. Sign in to your AdMob account at https://admob.google.com.
2. Click Mediation in the sidebar.
3. Click the Bidding sources tab.
4. Select the ad source you want to change the secure signals settings for.
5. Click the Settings tab.
6. Click the toggle next to "Secure signal sharing" to turn it on or off.
