Chrome Lighthouse adds an Agentic Browsing audit category
Google has added an experimental Agentic Browsing category to Chrome's Lighthouse audit tool. Instead of auditing only for human users, the new category tests whether AI agents can read a site, navigate key pages, understand actions and forms, and reliably interact with elements.
What changed
Setup requires Chrome 146 or later, enabling a WebMCP testing flag, and selecting the Agentic Browsing category in DevTools. The audit currently checks LLMs.txt implementation, WebMCP compatibility, accessibility labelling and roles, and layout stability.
Why it matters for advertisers
For you, this means SEO and development teams can now test how AI agents experience their site, not just human visitors. Worth running the audit on priority templates to identify where machine-readability gaps could block AI agents from navigating or transacting.
