Google updated its crawling documentation on September 17, 2026 to clarify that crawling preferences addressed to the Mediapartners-Google user agent can affect multiple ad-related Google products, not only AdSense.
Google says it generalized the Mediapartners-Google crawler documentation and renamed the relevant section because the crawler is used by various ad-related products, including Google AdSense and Google Ad Manager.
For technical SEO and publisher teams, the practical lesson is to avoid assuming that a crawler rule has consequences for only one Google product because of an older section label. Before changing robots.txt or other crawling controls, verify the current first-party documentation and understand which systems may rely on that user agent.
This is a documentation clarification rather than a reason for ordinary business websites to add new crawler rules. Clever Ape Academy recommends leaving working crawl controls unchanged unless there is a specific, verified requirement and testing any change carefully so important content is not blocked unintentionally.
