What changed
Google is consolidating data controls between GA4 and Google Ads, effective June 15 2026
Google Signals settings are changing as part of the merge
Consent Mode will become the single control point for how user data flows between platforms
What it means
If you run Google Ads and GA4 together (most Australian advertisers do), the way your platforms share audience and conversion data is about to change. Consent Mode will become the gatekeeper. Businesses without proper Consent Mode implementation risk losing remarketing audiences, conversion modelling accuracy and cross-platform reporting. This is not a feature update. It is a structural change to how Google's advertising and analytics ecosystems talk to each other. The June deadline gives you less than two months to prepare.
What to do
Audit your current Consent Mode implementation (check if you are running v2 with both ad_storage and analytics_storage parameters)
Verify your cookie consent banner fires Consent Mode signals correctly before and after user interaction
Review your GA4 > Admin > Data Settings to understand current Google Signals configuration
Test your Google Ads conversion tracking to confirm it still reports accurately under Consent Mode restrictions
