Google Previews Meridian GeoX and Data Manager Updates

Google has offered a sneak peek at several upcoming enhancements to its advertising measurement toolkit, unveiling a new open-source incrementality testing solution alongside an enterprise-grade platform for marketing mix modeling. These previews arrive just ahead of Google Marketing Live on May 20, where the company plans to reveal further details on the evolution of Google Analytics.

What’s New

The announced updates span three critical areas: data management, incrementality testing, and marketing mix modeling.

Data Manager Updates

Google’s Data Manager will soon feature a refreshed visual summary with an integrated map view, expected to roll out in the coming months. This new interface will illustrate how data flows from platforms such as BigQuery, Google Drive, HubSpot, and Shopify into Google Ads, Google Analytics, and the Google Marketing Platform.

In the next few weeks, the Data Manager API will enable advertisers to combine foundational tags with additional data signals, including store sales. The Google tag is also receiving a visual setup flow, allowing marketers to configure it without writing any code. Google states this update will centralize settings and user access, simplifying the process for non-technical marketers.

Citing internal data from the finance sector, Google reported that advertisers who upgraded to the Google tag gateway saw an average of 14% more conversions. The company credited partners like Akamai, Cloudflare, Fastly, Google Cloud, and Webflow for driving adoption.

Meridian GeoX

Google introduced Meridian GeoX, describing it as an open-source, geographic-based incrementality solution. This tool is designed to run geographic experiments that deliver causal measurement of media performance. Built on an auditable codebase, GeoX integrates with Meridian, Google’s open-source marketing mix model. Testing is set to begin later this year.

The methodology behind GeoX is not entirely new. Google’s GitHub repositories for geographic experiment matching (google/trimmedmatch and google/matchedmarkets) have existed for some time. This announcement formalizes the technology as a named product within the broader Meridian ecosystem.

Meridian Studio

Google is also launching Meridian Studio, a Google Cloud-powered enterprise platform for teams managing high-volume marketing mix models. The company says it offers customization options and access to a richer signal base. Google listed eight measurement partners for its Meridian and Data Manager tools, including Adswerve, Choreograph (WPP), Brainlabs, Epsilon, Fifty-Five, Jellyfish, Making Science, and Merkle.

Why This Matters

Google is weaving several measurement tools into a cohesive narrative centered on stronger first-party data, causal experiments, and marketing mix modeling. Meridian GeoX adds an incrementality layer to Meridian, giving advertisers a way to test media impact by geography. This is significant because MMM can show modeled relationships, while experiments can help validate whether media drove incremental results.

Google has been building toward this across its measurement products. Recent examples include Tag Diagnostics, Meridian’s launch, a Data Manager API expansion, and Scenario Planner. The main limitation is timing. Data Manager updates are arriving in stages, GeoX testing begins later this year, and Google has not shared access details for Meridian Studio.

Looking Ahead

Google said it will share more at Google Marketing Live on May 20, including how it plans to connect data and causal measurement across its ad products. The company also teased upcoming Google Analytics changes but did not provide specifics. Until then, the key open questions remain: when each tool becomes available, who can access Meridian Studio, and how GeoX testing will work in practice.
