Microsoft introduced fresh content preferences on October 30, 2026, offering site owners distinct choices for managing how their pages interact with artificial intelligence. According to Search Engine Roundtable, the new Microsoft Bing AI controls separate model training from search grounding so publishers can make precise selections without losing traditional search visibility.
Key takeaways
- Microsoft announced new Bing AI content controls to let publishers choose preferences for training and grounding.
- Site owners can block AI training while still letting Copilot cite their articles in generated answers.
- Temporary grounding controls arrive in Bing Webmaster Tools on December 15, 2026.
- Google, OpenAI, and Anthropic are also on board with shared preferences in robots.txt.
What do the new Microsoft Bing AI controls mean for publishers?
Publishers gain three main choices under the update. The AI training setting lets sites allow or prevent content from training AI models. Meanwhile, the AI grounding setting controls whether content generates AI answers. A limited grounding setting supports Microsoft's own products while blocking third-party grounding services.
Search Engine Roundtable reports that you can block AI training but still appear in AI answers. For instance, a publisher can stop Microsoft from using articles for training while allowing Copilot to cite those same pieces. Blocking AI answers can reduce visibility in AI experiences, but traditional Bing rankings remain unaffected.
When do the new AI training preference rules take effect?
Temporary grounding controls become available in Bing Webmaster Tools on December 15, 2026, for eligible sites using older NoArchive or NoCache directives. Microsoft begins honoring the new preferences during crawls on February 1, 2027.
March 1, 2027 marks the deadline for publishers using old directives to configure the new preferences to keep restrictions active. Temporary grounding preferences eventually expire on September 30, 2027. Bing Webmaster Tools also features AI Performance reporting showing citations, cited URLs, and grounding queries.
Why it matters for site owners
Site owners get granular control over digital content by separating model training from AI answer generation. Microsoft is joining industry peers to announce a shared AI training preference in robots.txt while offering page-level training preferences and separate grounding rules.
