Google plans shared training control for 2027, retaining Google-Extended
Google specifies its planned timing and interpretation; this is not live activation or a traffic guarantee.
Google announced planned support for a shared robots.txt AI-training preference on October 30. The announcement targets 2027; crawler documentation says early 2027, with no exact date. If a site opts out through the shared signal and does not explicitly set Google-Extended, Google plans to treat it as disallowing Google-Extended. Existing provider-specific controls remain.
Google-Extended covers Gemini training and certain grounding uses. It does not affect inclusion or ranking in Google Search. Allowing relevant uses can provide eligibility, not guaranteed citations, clicks or revenue. This is a future adoption plan, not a completed industry-wide standard. We have not changed robots.txt or tested implementation.
