Lighthouse Agentic Browsing measures technical signals related to a page’s ability to be understood or used by agents. Public signals include llms.txt, WebMCP, accessibility, programmatic names of interactive elements and layout stability.
It does not measure full agentic readiness. It does not always know whether the offer is clear, whether proof is well connected, whether the right CTA is selected, whether an action consequence is sufficiently explained or whether the site properly governs its limits.
At Pagup, Lighthouse is therefore an entry signal. The Lighthouse Agentic Browsing Audit interprets those signals, then the Agentic Readiness Audit verifies real journeys.
