What is GoogleOther?

A generic Google crawler used for various internal tasks and research that don't directly affect search ranking, such as R&D.

A generic Google crawler used for various internal tasks and research that don't directly affect search ranking, such as R&D. GoogleOther is one of Google's specialised crawlers, distinct from the general Googlebot. It serves a specific Google product (Images, Video, News, etc.) and uses the user-agent GoogleOther. Selectively blocking it disables the corresponding Google feature for your site (e.g., blocking Googlebot-Image removes your images from Google Image Search). Always verify which Google product is affected before blocking.

What happens if you block GoogleOther?

⛔ **Critical Impact** — Blocking GoogleOther will stop Google from crawling and indexing your pages. Within days or weeks you may see pages drop out of Google's search index entirely, resulting in a significant loss of organic search traffic. This is the most severe possible SEO consequence. Only do this intentionally, for example if you are migrating to a different search engine or decommissioning a domain. If you accidentally blocked GoogleOther, remove the rule immediately and request re-indexing via Google's webmaster tools.
Never block — it will remove your site from major search results.

Is GoogleOther safe to allow?

Yes, GoogleOther is a **safe and legitimate** crawler. It is operated by Google, which publicly documents its crawler at an official URL and follows the Robots Exclusion Protocol (RFC 9309). The user-agent string GoogleOther is verifiable via reverse-DNS lookup on the crawling IP addresses. You can safely allow it unless you have a specific reason to block (e.g., AI training opt-out or SEO tool visibility).
Verify by reverse-DNS lookup: legitimate GoogleOther requests resolve to google's domain.

Will blocking GoogleOther hurt my SEO?
⛔ **Critical Impact** — Blocking GoogleOther will stop Google from crawling and indexing your pages. Within days or weeks you may see pages drop out of Google's search index entirely, resulting in a significant loss of organic search traffic. This is the most severe possible SEO consequence. Only do this intentionally, for example if you are migrating to a different search engine or decommissioning a domain. If you accidentally blocked GoogleOther, remove the rule immediately and request re-indexing via Google's webmaster tools.
How do I block GoogleOther in robots.txt?
Add the following lines to your /robots.txt file: 
User-agent: GoogleOther
Disallow: /
This instructs GoogleOther not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable — any bot or human can inspect it at yourdomain.com/robots.txt.
Does GoogleOther respect robots.txt?
Yes — GoogleOther is a well-behaved bot operated by Google. It fetches and parses /robots.txt before crawling any page, following RFC 9309.
How do I verify if GoogleOther is crawling my site?
Search your web server access logs for the string GoogleOther (case-insensitive grep: grep -i "GoogleOther" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For GoogleOther specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of GoogleOther?
Critical-impact search crawlers like GoogleOther typically crawl popular pages daily and less popular pages weekly. You can manage crawl rate via the crawl-delay directive or via the search console.
Can I block GoogleOther from specific pages only?
Yes. Instead of a global Disallow: / you can restrict GoogleOther to specific paths: 
User-agent: GoogleOther
Disallow: /private/
Disallow: /staging/
Allow: /
This allows GoogleOther everywhere except the listed paths. Path matching in robots.txt uses prefix matching — Disallow: /private/ blocks /private/page.html but NOT /public/private/.
