Nozzle found that 8.0% of Google search result pages it analyzed were missing most of the usual positions for their keywords, compared to a baseline of 0.17%, according to Search Engine Journal.
The company analyzed 17.8 million result pages between September 13 and October 9, 2026, and the percentage of affected pages peaked at around 25% between September 27 and 29.
In a separate development, sessions attributed to ChatGPT in GA4 dropped by about 45% after embedded links lost the utm_source=chatgpt.com tag.
OpenAI confirmed the bug on October 14 and began deploying a fix on October 15, according to the same source.
