Google Ads adds a diagnostics hub for data connections

Google Ads rolled out a data source diagnostics feature inside Data Manager that helps advertisers monitor the health of their data connections. The tool flags issues tied to offline conversions, CRM imports, and tagging mismatches.

How it works. A centralized dashboard assigns clear connection status labels — Excellent, Good, Needs attention, or Urgent — and surfaces actionable alerts. Advertisers can see problems like refused credentials, formatting errors, and failed imports alongside a run history showing recent sync attempts and error counts.

Why we care. When conversion data breaks, campaign optimization breaks with it. Even small data connection failures can quietly distort conversion tracking and weaken automated bidding. This diagnostics tool helps teams spot and fix issues early, protecting campaign performance and reporting accuracy. For advertisers relying on CRM imports or offline conversions, it adds a much-needed safety net.

Who benefits most. The feature is particularly useful for advertisers running complex conversion pipelines, including Salesforce integrations and offline attribution setups, where small disruptions can ripple into bidding and reporting.

The bigger picture. As automated bidding depends more heavily on accurate first-party data, visibility into data pipelines is becoming as important as campaign settings themselves.

Bottom line. Google Ads is giving advertisers an early warning system for data failures — helping teams fix broken connections before performance takes a hit.

First seen. This update was first spotted by Digital Marketer Georgi Zayakov when he shared spotting the new option on LinkedIn.
