Google-Extended is a standalone crawler used by Google to fetch web content specifically for training and improving its artificial intelligence models. Unlike the standard Googlebot, which indexes pages for search results, Google-Extended focuses on gathering data to enhance machine learning capabilities. When you see this user agent in your server logs, it indicates that Google is accessing your site to process information for its AI products. Site owners can control this activity by using robots.txt directives to allow or disallow the Google-Extended bot, providing granular control over how their site's data is utilized for AI training purposes across the web.
- Google-Extended is explicitly documented by Google for AI training purposes.
- Server logs provide clear visibility into the frequency of Google-Extended requests.
- Robots.txt allows site owners to opt-out of Google-Extended data collection.
