Restaurant
Is it open today, does it have a gluten-free menu and can I book for eight people?
Before, or without enough evidence
I cannot find sufficiently clear and current information to confirm hours, menu or reservations.
The call
It is not only the ways of communicating that change, but also who communicates.
Your website no longer speaks only to people. Search engines, assistants and agents try to discover what it does, what they may cite and which tools they may use. Agent Friendly Web makes that conversation readable, verifiable and governed.
Maturity path
Agentic transformation happens in layers.
Each level adds observable evidence or control. A roadmap does not count as a deployed capability.

What does it mean for a website to be agent friendly?
An agent-friendly website combines clear content, coherent public routes, structured data, sources, dates and boundaries. Tools are declared only when they exist, while sensitive actions retain identity, permission, audit and human control.
Is progression from AF-0 to AF-5 automatic?
Each level requires verifiable work: publish evidence, implement the capability, test it, declare boundaries, obtain human approval where needed and measure again. Not every website needs to reach AF-5.
What does the public audit inspect?
The audit observes discovery, citable content, machine-readable resources, tools, experimental signals, trust and commerce. The result is a proprietary measurement, not certification or a ranking or recommendation guarantee.
What are robots.txt, sitemap.xml and agent documents for?
robots.txt guides crawling, sitemap.xml lists canonical pages, and documents such as llms.txt or catalogs describe knowledge and capabilities. No single file guarantees that a provider will index, cite or recommend the website.
What is llms.txt and how is llms-full.txt different?
llms.txt works as a concise index while llms-full.txt provides expanded public context. They are not universal standards and do not replace HTML, sitemaps, structured data, APIs or editorial review.
What is AEO and how does it relate to SEO?
SEO and AEO complement each other. SEO helps pages get found; AEO improves answer clarity and citability. Neither can promise a particular position, citation or recommendation.
Every capability has a file, evidence and a boundary.
Documents can grow without changing the F0-F5 path. Open each file to see what is truly published and what still has a gate.
