Google Ads Multi Source

Google posted another new help document on multi-source conversions (beta). Last month, Google reportedly renamed conversions with multiple data sources to multi-source conversions, but now there is this new help document as well.

Multi-source conversions allow advertisers to connect an existing website conversion action with an additional backend data source, such as a CRM or order database, via Data Manager or the Data Manager API," Hana Kobzová said back then.

The new help page is named Multi-source conversions in Google Ads (beta) - it explains:

You can now boost your website performance by connecting your tag with an additional data source. By connecting additional data sources to your Google tag web conversion, you can gain a more complete understanding of your conversion measurement, fill in any potential gaps, and improve your overall performance.

By combining your tag-based website measurement and your additional data you can supplement the online signals captured by your Google tag with additional conversion data uploaded with Data Manager or Data Manager API from your backend systems, like a CRM or order database.

The benefits include:

  • Resilient and accurate measurement: Mitigate signal loss from browser restrictions and ad blockers for a future-proofed setup. Integrating an additional data source from your backend systems can help recover conversions that may be missed by the Google tag due to browser settings or ad blockers.
  • Unlock better bidding: More comprehensive data leads to better bidding outcomes. Your role helps validate these gains.
  • Simpler, integrated setup: Uses the new Google Ads Data Manager for a more intuitive experience.
  • Adjust real-time conversion values: Send accurate financial updates such as restatements, upsells, or finalized cart totals from your CRM to override the value recorded by the tag.
  • Enhance measurement accuracy: Supplement your tag with missing user-provided data such as email or phone number to mitigate signal loss, recover conversions that might be missed by the Google tag, and unlock better bidding.
