# Finding Google-Extended in a server log is impossible | Illia BizTech

> Why does Google-Extended appear in no log file? Because the name carries no user agent string of its own and exists only inside robots.txt.

# A monthly report counts Google-Extended, and the log knows no such name

A figure arrives from the contractor every month, and that name appears nowhere in the raw file.

Since the start of 2026 we have received a monthly report on AI requests. It carries a line for Google-Extended with a figure that moves month to month.

I went through our raw log myself across several months. That name is not in it once. Have I filtered it wrongly?

Your filter is fine. Google's crawler documentation, last updated 14 July 2026, states that Google-Extended has no separate HTTP request user agent string. The fetching is done with existing Google user agent strings, and the name exists only as a control word inside robots.txt.

A figure under that name therefore cannot have come from a log file. It is either derived from something else or simply asserted. Ask your contractor which raw log line sits behind it, and ask to see that line.

A second sentence on the same page is worth quoting, because it is often sold the other way round. Google-Extended does not affect a site's inclusion in Google Search and is not used as a ranking signal there. What the control word governs is training and grounding for Gemini applications.

For whether you appear in the AI results of Search itself, a separate setting in Search Console governs that, and it is a different lever entirely. While you are working out who sends you which numbers, the [AI visibility report](https://illia-biztech.de/en/ki-sichtbarkeitsbericht) from Illia BizTech shows what a measurement with a traceable origin looks like.

Google-Extended is a control word and was never a visitor. Google's crawler documentation records that it has no separate HTTP request user agent string and that fetching happens with the company's existing agent strings.

Two things follow. A report counting requests under that name cannot have taken them from a log file. And the control word itself governs training and grounding, while inclusion in Google Search and ranking within it stay outside its scope.
