Google shipped an opt-out from AI Overviews and AI Mode, and we told you it did not exist
Google's help documentation describes a per-property setting with three values: the default, which is include, an explicit exclude, and inherit from parent. Exclude stops a site's content appearing in AI Overviews, AI Mode and the generative AI features in Discover, and stops it being used to ground answers in those features. Google is explicit that this costs nothing in ordinary search, verbatim: "This control only affects whether your content can appear in certain Search generative AI features; this control isn't used as a ranking or inclusion signal affecting other parts of Search." The documentation says the change takes one to two days to take effect, and that the control is going to "a subset of website owners" without naming a country. PPC Land reported on 3 June that it exists because the UK Competition and Markets Authority ordered it under the Digital Markets, Competition and Consumers Act 2024, and that the main obligations take legal force on 3 December 2026.
