Google Signals is an advertising reporting feature through which GA4 can collect cross-device data from those website users who have signed in to one of their Google accounts (Gmail, YouTube, etc) and have turned on ad personalization.

When you activate Google Signals for your GA4 property, you can:

1. More accurately track users across different devices and platforms.
2. Remarket to more website users across devices.
3. Analyze users’ data by age, gender and interest.

Note: Google Signals is not enabled by default in GA4.
