Google’s Search generative AI control becomes available worldwide

What changed

Google's Search Console guidance states that the Search generative AI control reached websites worldwide on 31 August 2026. It covers inclusion of a site's content and links in AI Overviews, AI Mode and supported generative features in Discover. The choice concerns those experiences; Google's guidance says it does not govern model training or override separate participation in Google Ads and Merchant Center.

Site structure is an important part of the decision. A child property can inherit its parent's choice unless its owner configures it separately. A commercial team reviewing one section of a site should therefore establish which property actually controls it. A change at a broader level could affect multiple sections with different purposes, while a local override can mean that two parts of the same business are treated differently.

The source also describes a propagation period rather than an instantaneous change. That makes it important to record the setting, scope and change date before comparing traffic. A short-term movement cannot automatically be attributed to the control, because demand and other search changes can move at the same time. The guidance does not supply a forecast of the revenue effect for a particular publisher or retailer, and that effect should remain a business-specific question.

Why it matters for advertisers

For advertisers, this is a coordination issue across the people responsible for search visibility, content and commercial channels. A decision about unpaid generative-search inclusion may affect discovery while paid campaigns and Merchant Center participation continue under their own arrangements. Evaluate the relevant exposure and traffic alongside the site's objectives before using a property-wide control, and make the intended scope understandable to all owners.
