Summary
Editor's update, October 2026: 19 Oct 2026 accuracy audit: reframed as advertiser measurement tool; empty copy written.
Google's privacy-centred warehouse for marketers, agencies and measurement partners to join their first-party data in BigQuery with Google ad event data and receive aggregated results.
Ads Data Hub is Google's clean room for advertising measurement. Marketers, agencies and measurement partners upload first-party data to BigQuery and join it with event-level campaign data from Google products, then query it with SQL. Results come back aggregated across groups of users, so no user-level records are exposed. It is built for advertisers and their partners; publishers appear in it only as data, not as users.
Its standout capability is depth of Google media measurement: queries can combine Campaign Manager 360, Display & Video 360 and YouTube data, including viewability metrics, with an advertiser's own app, offline transaction or connected-ID data, and audiences built from the analysis can be used in other Google ads products.
The limitations are access and reach. Google's developer documentation is marked as legacy and describes the product as a closed beta, so availability should be confirmed with a Google account team. Privacy checks can filter result rows without warning, analysis is confined to Google data, and running it needs SQL and Google Cloud skills.
