Fresh out the oven, still warm. Top of the tray.
Summary
Google has added llms.txt to its Chrome Lighthouse toolset under a new "Agentic browsing audits" section, signaling that the company now considers AI-agent readiness a legitimate web standard. The move, which took place on May 5, 2026, has reignited debate among SEO and marketing professionals about whether the nearly two-year-old llms.txt specification is gaining practical traction or remains a theoretical standard without meaningful platform backing. The update places llms.txt alongside WebMCP, accessibility, and layout stability checks in Lighthouse's expanded audit suite.
