Agentic Landmark · The Brief

Most agent-ready advice collapses two different problems into one. Being cited and being usable run on different infrastructure, fail in different ways, and must be fixed in a fixed order. A map of the four-standard stack, from robots.txt to WebMCP, and why the sequence is the argument.
Every brand spent years learning to be memorable to humans. The next decade is about being legible to machines, not the same skill. A machine-readable brand is not good SEO or a chatbot. It is identity, claims, and offerings as structured data an agent can retrieve and reason from.
Contentful's Palmata makes one thing measurable: how answer engines represent your brand, past visibility into why and what to change. The measurement layer for AI discovery is now a category, not a feature. But it measures representation, not transactability, and that instrument does not exist yet.
Google says you do not need llms.txt for Search, and it just added a Lighthouse check for it. Both are true, because they answer to different audiences. It is not a search signal; it is an agent signal, the site's way of telling a browser agent where to start. Google is now measuring both.
Google's new guidance says you are overthinking AI search, no llms.txt, no AI-specific pages, no overfocus on structured data. For Google's own search features, that is right. For an agent querying your catalog through ACP or UCP, it is the opposite.
