Googlebot-Image — Google's image crawler
Googlebot-Image is the Google crawler that fetches image files for Google Images. It uses the Googlebot-Image robots.txt user-agent token and is documented among Google's common crawlers, so operators can target image crawling separately from page crawling.
What this means
Googlebot-Image is Google's dedicated crawler for image content that may appear in Google Images. Google lists it among its common crawlers with its own robots.txt user-agent token, distinct from the main Googlebot page crawler.
Because it has its own token, you can allow normal page crawling while restricting image crawling, or vice versa, by targeting Googlebot-Image specifically.
robots.txt considerations
Googlebot-Image honours robots.txt. To keep your images out of Google Images while still allowing page crawling, target the Googlebot-Image token with a Disallow rule. Verify suspect requests using Google's reverse-DNS and published IP-range method, since the user agent is spoofable.
- robots.txt token: Googlebot-Image
- Separate control from the main Googlebot page crawler
- Verify via reverse DNS to googlebot.com / google.com
How it appears in analytics and logs
A request carrying the Googlebot-Image token is Google fetching an image file for Google Images, not a page. It is bot traffic; treat regular image crawling as the normal state for sites that want image search visibility.
Diagnostic use case
See whether Google is crawling your image files for Google Images, and allow or restrict image crawling independently of normal page crawling.
What WebmasterID can help detect
WebmasterID classifies Googlebot-Image server-side as a search crawler and surfaces its activity separately from human traffic, so image-crawl coverage is visible without log parsing.
Common mistakes
- Assuming a Disallow on Googlebot also blocks Googlebot-Image — they are separate tokens.
- Counting image-crawl hits as human page views.
- Trusting a Googlebot-Image user agent without verification.
Privacy and accuracy notes
Identification uses the user agent plus Google's reverse-DNS/IP verification — no human identity. WebmasterID records Googlebot-Image as a bot event, separate from human analytics.

Googlebot Desktop is the desktop user-agent variant of Googlebot. Under mobile-first indexing it is secondary to Googlebot Smartphone for most sites. It shares the Googlebot robots.txt token and is verified the same way: reverse DNS into googlebot.com or google.com, or matching Google's published crawler IP ranges.
