Lighthouse previews experimental agentic browsing audits

An experimental diagnostic

Chrome describes the Lighthouse Agentic Browsing category as experimental and based on proposed standards. Testing requires Chrome 150 or later, while WebMCP audits additionally require participation in the relevant origin trial.

The report does not assign a weighted score from zero to one hundred. It displays a fractional pass ratio, pass or fail results and informational counts. This developer diagnostic has not been announced as a Google Search ranking factor.

What the audits check

Checks include WebMCP registration, accessible names, accessibility-tree integrity, visibility of interactive elements, layout stability and the presence of an llms.txt file.

For a PrestaShop store, these areas may improve accessibility and the reliability of automated interactions. They should be treated as reproducible technical tests, not as a promise of visibility or sales in AI search systems.
