Human-readable vs machine-understandable
A useful website already needs to be understandable to people. Clear headings, public explanations, accessible navigation and obvious next actions help a buyer make a decision. Agent readiness adds another consideration: can a machine identify the company, its offer, its proof, its limitations and the available action without having to infer those facts from a visual layout alone?
The goal is not a second hidden version of the site. People and machines should receive the same factual public content. Semantic HTML, stable URLs, readable page structure and accurate metadata make information easier to use without replacing the human experience with a protocol demo.
