Google signals

Google signals is a GA4 feature that uses data from signed-in Google users who consented to ads personalisation, to enable cross-device reporting.

Written by Reflective Data experts · updated Oct 5, 2026

When enabled, GA4 can associate sessions across devices for those users and unlock features like demographics and remarketing audiences. It also increases the chance of data thresholding.

Check your consent set-up and legal basis before turning it on.
