Google told us that Google-Extended does not work for SGE. “SGE is a Search experiment so website administrators should continue to use the Googlebot user agent through robots.txt and the NOINDEX meta tag to manage their content in search results, including experiments like Search Generative Experience,” a Google spokesperson told us. Google explained that SGE is part of the Google Search experience; it is a search feature and thus it should work as how normal search directives work. There are examples of SGE showing AI-generated answers, with website cards, from sites that have specifically directed Google not to use their content for AI purposes. If you thought using Google-Extended would prevent Google from using your content for SGE AI-powered answers, then you were wrong.
