Text-only versions of websites strip out the one layer AI agents need: the actions. Markdown mirrors serve prose to the visitor most eager to act.

In February 2026, I wrote that serving markdown to AI agents solves the reading problem and not the doing problem. Seven months on, one platform, Shopify, has touched the doing problem, and the markdown mirrors, the readiness scores, and GEO, the discipline for getting cited in AI answers, have not.

The text-only versions now being served to AI do not merely fail to carry actions; they strip them out. A markdown mirror of a web page is prose. Whatever a visitor could have pressed is gone by the time the machine receives it.

Heavy JavaScript is absolutely unnecessary for a website that is not some kind of web app, and the visual layer is not essential for machines either, especially if the structural layer is healthy. So put up a website that you know for certain no person will ever open, as an exercise, and both go. Layout, navigation, the design system, the image treatments, and the hierarchy that tells an eye where to land all go with them, and nothing is lost.

Structured data is content written for machines and invisible to people. JSON-LD alone is on 55.6% of the websites W3Techs measures, as of September 2026. Structured data survives the exercise because a person was never its audience.

The markdown mirrors and the readiness scores released since February are newer members of the same family.
