Our take

On 21 October Google updated its Control what you share with Google Search page. It now lists the robots meta tag, data-nosnippet, X-Robots-Tag and the Search generative AI control, which Google calls existing options. The new section says site owners can manage inclusion in generative AI features, including AI Overviews and AI Mode, with the Search generative AI control in Search Console.

The control is site-wide, not per page. Nothing new can be switched on, and Google presents it as housekeeping.

My read: the useful part is the placement. The AI Overviews opt-out now sits on the same page as noindex and robots.txt, so it reads like a normal choice every site owner should make on purpose.
