Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/wordpress/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # WordPress: vendor profile In short WordPress core renders pages through themes on the server, with a core sitemap, a virtual robots.txt and 404 handling. Plugins or custom code add llms.txt, markdown and JSON-LD. The markdown on WordPress.org's own sites is custom work by the Meta team, switched on for most of that network since 2026-03-03. ## At a glance **standards.txt** wordpress ```text llms-txt = partial markdown-negotiation = partial markdown-twin = partial initial-html = supports real-404 = supports vary-accept = partial ``` 2 supports, 4 partial or announced, 0 no statement. **WordPress** Content management system WordPress is open-source PHP software whose themes render pages on the server, with a core XML sitemap, a virtual robots.txt and real 404 handling; llms.txt and markdown output come from plugins, not core.

the markdown on wordpress.org itself is custom work by the WordPress.org Meta team. - WordPress core prints no JSON-LD structured data, so schema comes from the theme or an SEO plugin. - The core robots.txt from do\_robots() names no AI crawlers; blocking them takes a robots\_txt filter, a physical robots.txt file or a plugin. ## Related pages on this site - [Content management systems in this section](https://agentreadyhtml.com/vendors/by-type/cms/) - [WordPress and Elementor: platform profile and rubric scores](https://agentreadyhtml.com/platforms/wordpress-elementor/) - [The Plain Fetch viewer](https://agentreadyhtml.com/viewer/) ## Sources 1.
