Google reports logging bug in Search Console Generative AI report

Nov 12, 2026
Impressions in the Search Console Generative AI performance report were undercounted from 9 to 11 November. Google says only data logging was affected.

Google has confirmed a logging error in the Generative AI performance report in Search Console. It lowered the impressions shown in the report for data from 9 to 11 November 2026, Search Engine Roundtable reports.

Google posted the issue on its data anomalies page. It wrote that a logging error caused a decrease in impressions on the Generative AI performance report for those dates, and that "this issue affects data logging only."

Search Engine Roundtable notes that Google's November 2026 core update started on 10 November, during the same period. According to the site, the drop in impressions for those dates is a reporting bug and had no effect on how pages performed in Google Search.

The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
