As AI agents increasingly browse websites autonomously, the accessibility tree—originally built for screen readers—has become the primary machine-readable interface to your content. This inverts the compliance logic of the last decade: accessibility features are no longer optional accommodations but core infrastructure. Semantic HTML and ARIA markup now determine whether automated visitors can parse your site. Companies optimizing only for human visual design while neglecting these standards are effectively invisible to the AI agents that will route traffic and transactions in 2026.
