GoogleOther
Google's generic crawler, used by various product teams for one-off crawls and research. Its rules affect no specific product.
Where this comes from
- Documented by the vendor. Source: developers.google.com
- Honours robots.txt.
- Listed, not scored. It cannot keep a site out of today's answers, so the check shows a block without deducting for it.
In the top 1,000 websites
- 11.1% block it in robots.txt (63 of the 569 sites with a robots.txt), as of 2026-10-12.
- Method, limits and the full data: the October 2026 study of the top 1,000 websites.
What blocking it costs
Nothing: Google says the GoogleOther crawls affect no product. The check lists the block without deducting for it.
The robots.txt lines
To let it in (a group that names the crawler replaces any wildcard rules for it, so this also lifts a User-agent: * block):
User-agent: GoogleOther
Allow: /To keep it out:
User-agent: GoogleOther
Disallow: /A rule in robots.txt is a request. Google AI says this crawler honours it. The robots.txt generator writes a whole file with the same split: block the training crawlers, keep the search and answer crawlers.
