About Google-xrawler

Google's user-triggered fetcher for merchant product feeds. Fetches XML product feeds from e-commerce sites for syncing with Google Merchant Center.

Search engine crawlers index your pages so they can appear in search results. Keep the genuine ones allowed and verify them, because fake search crawlers are one of the most common disguises for scrapers.

Google-xrawler user agent

Google-xrawler identifies itself with this user agent string:

  • google-xrawler

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block Google-xrawler in robots.txt

We have not confirmed whether Google-xrawler follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: google-xrawler group, Google-xrawler ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take google-xrawler from Google-xrawler's user agent; check Google's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. Google-xrawler may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that Google-xrawler follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send Google-xrawler's user agent, and a scraper using it is not bound by Google's robots.txt policy. Only checking the source network tells a real Google-xrawler from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
