Pre-GML measurement preview: Data Manager Map View, Tag gateway, Meridian Studio
Ahead of Google Marketing Live on 21 May, Ginny Marvin has previewed Google's measurement update set, framing the announcements as a shift from measurement as a report card to a growth engine. The release covers several substantive additions.

This video plays in the original LinkedIn newsletter.
What changed
Data Manager Map View provides a visual overview of how first-party data flows across BigQuery, HubSpot, Shopify, and other connected sources in Google Ads. Google Tag Upgrades let advertisers add new signals and store sales data with zero coding required.
The Data Manager API combines foundational tags with richer customer signals, with a stated rollout horizon of weeks rather than months. Meridian GeoX delivers geo-level incrementality testing with open-source, CFO-ready outputs; Meridian Studio is the Google Cloud enterprise platform for building and scaling MMMs at speed.
Why it matters for advertisers
For you, this means measurement infrastructure decisions made before Google Marketing Live will determine how much value the post-GML product roadmap can deliver. Worth auditing first-party data connections inside Data Manager before the 21 May announcements drop, particularly for advertisers running offline conversion imports or BigQuery integrations that have not been touched since the original setup.
