Google search console has confirmed that there is a data reporting problem that has been in play in terms of impression measures over months. Google reported that an error in logging did not allow the correct recording of impressions since May 13, 2025, and that it is currently in the process of making corrections.
This correction can result in a decrease in the number of impressions reported by the web site owners. Nonetheless, the change manifests the improvement of the accuracy of the data, but not the decline in the search visibility or rankings.
What Google Officially Confirmed
On April 3, 2026, Google revised its Data anomalies in Search Console documentation to include the following:
A logging error prevented Search Console from accurately reporting impressions from May 13, 2025 onward.
The issue is being resolved over the next few weeks, and as a result, impression data may decrease.
Clicks and other metrics were not affected.
This confirms that:
- The issue was technical (logging-related)
- It impacted impression reporting only
- The fix is currently in progress
Understanding the Impression Reporting Issue
The problem was caused by a logging error in data collection, which led to inaccurate impression counts in reports.
What this means in practice:
- Impression data shown since May 13, 2025 was not fully accurate
- The issue did not affect actual search performance
- Only how data was recorded and displayed was impacted
This distinction is critical. The issue is about measurement, not visibility.
Why Impressions May Now Appear Lower
As Google resolves the issue, impression data is being corrected.
According to Google the fix will roll out over several weeks and during this time, reports may show lower impression counts. The change reflects improved accuracy, not a decline in performance.

What You Should Do
Avoid making SEO changes based solely on impression drops during this period. Instead, focus on more reliable metrics such as clicks and overall traffic to assess performance accurately. It’s also a good idea to add an annotation in your reports to mark this timeframe as a data anomaly, so future analysis remains clear and contextual.
