Google checks websites for llms.txt in new agentic browsing audit

Google has announced a new test aimed at evaluating how well websites handle AI agents. This is being done through a new experimental category called "Agentic Browsing" in its Lighthouse analysis tool. The test includes checking for the presence of an llms.txt file on targeted websites. This initiative is part of Google's efforts to enhance website performance amid the growing use of AI agents. By conducting this test, Google can assess how prepared websites are to interact with AI technologies, which may influence their ranking in search results.
