Google has confirmed a major bug affecting offline conversion uploads in Google Ads.
Advertisers say a large part of their uploaded conversion data is missing from reports. This issue is now impacting campaign performance, results, and automated bidding.
The company has acknowledged the problem and says a fix is in progress.
Advertisers Report Missing Offline Conversions
The issue came to light when multiple advertisers noticed sudden drops in their reported conversions. Many said that only a small portion of their offline uploads were being processed.
Key issues reported:
- Around 80% of offline conversions fail to appear in Google Ads
- Reporting shows incorrect conversion numbers
- ROAS bidding strategies become unstable
- Campaigns show drops in clicks and performance
- Data mismatch affects overall optimisation
Prakash Chandra Durgapal highlighted the issue on X. He said that the missing conversions caused malfunctioning bid strategies and a sharp decline in campaign clicks.
