Google signals are session data from sites and apps that Google associates with users who have signed in to their Google accounts, and who have turned on Ads Personalization. This association of data with these signed-in users is used to enable cross-device reporting, cross-device remarketing, and cross-device conversion export to Ads.
Google signals enables:Cross Platform reporting
Connect data about devices and activities from different sessions using your User-ID or Google-signals data so you can get an understanding of user behavior at each step of the conversion process, from initial contact to conversion and beyond.
Cross-device activity is tracked when you log-in to a Google account using the following:
- iOS devices*
- Android devices
- Google Chrome
- Google Chrome web browser
- Other web browsers
- Client apps that require a Google account
- Other apps that require a Google account
* Google signals does not support iOS 14+ and upward devices (Apple no longer supports IDFA). For iOS 14+ devices, you must use User-ID tracking for cross-device tracking.
For your reports to include Google-signals data you need a monthly average of 500 users per day per property.
With the addition of Google-signals data, Google Analytics improves the accuracy of user counts in reporting, and uses cross-platform audience criteria to evaluate users who do not have a user ID.
Create remarketing audiences from your Google Analytics data, and share those audiences with your linked advertising accounts.
When you activate Google signals, audiences that you create in Google Analytics and publish to Google Ads and other Google Marketing Platform advertising products can serve ads in Cross Device-eligible remarketing campaigns to Google users who have turned on Ads Personalization.
Google Analytics collects information per your tagging configuration, as well as Google-signals data and Google advertising cookies that are present.
Google Analytics collects additional information about demographics and interests from device identifiers and from users who are signed in to their Google accounts and who have turned on Ads Personalization.
Data from users who have turned on Ads Personalization
When users turn on Ads Personalization, Google is able to develop a holistic view of how those users interact with an online property from multiple browsers and multiple devices. For example, you can see how users browse products on your site from a phone, and later return to complete purchases from a tablet or laptop.
By default, Google signed-in data expires after 26 months. However, if the Analytics Data Retention setting is set to anything shorter than 26 months, the Google signed-in data will respect this shorter time frame.
Data sharing with other Google products
Data collected under Google signals is not used or shared for any purpose other than to provide the Google Analytics service unless you enable Data Sharing settings or opt to link with Google products.

This setting applies regardless of whether Google signals is enabled; changing the ads personalization setting does not affect the collection of data for Google signals.
