Why agent-readiness matters now

AI agents are already landing on websites to answer questions people ask in Claude, ChatGPT, Copilot, Google AI Mode, Gemini, Grok, Perplexity, and other LLMs. That includes a customer-support bot, a coding assistant, or a research agent working for your customer.

The open question is whether your website makes sense to those agents when they arrive. Companies like Ramp, SerpApi, and others are already working through that.

The standards behind our agent-readiness package

The agent-readiness files we install are defined by published standards, working-group proposals and specifications, and Google guidelines. People, organizations, and companies you can look up write those rules.

The founding proposal

llms.txt was proposed by Jeremy Howard of Answer.AI in September 2024. His premise: "Site authors know best, and can provide a list of content that an LLM should use."

Google Chrome recognition

llms.txt is no longer a community-only proposal. As of May 2026, Google Chrome's Lighthouse includes an experimental "Agentic Browsing" audit for the file. That is developer tooling recognizing the convention for agents (absence is currently not applicable, not a failing check). It is separate from a Google Search ranking signal.

Academic specification

agent-permissions.json is a formal manifest published by the Lightweight Agent Standards Working Group (researchers from Oxford, Stanford, and Microsoft) in August 2025. It is one of the files we install.

We treat llms.txt as foundational for agent-readiness. We include it with the rest of your agent-readiness package (typically 13 files). To learn more, explore the agent-readiness package files, explained.

What Ramp learned when they marketed to AI agents

In early 2026, Ramp came to a realization: every company’s website was built for humans, and marketing to agents is becoming just as important. Across roughly 50 marketing pages, Markdown was the only tested format that reliably surfaced in LLM responses, while model behavior diverged sharply over a 32-day window.

That is empirical B2B evidence for agent-readable Markdown files. The caveats still apply: no citation, ranking, or conversion guarantees, and progress tracked over time.

We solve agentic browsing, and leave SEO fundamentals to your SEO work

Google's guidance on AI features in Search says special AI files, AI-only markup, or llms.txt files are not required to appear in AI Overviews or AI Mode or to achieve a higher ranking in results. The same applies to regular Google Search.

AI Overviews, AI Mode, and regular Google Search rely on established SEO fundamentals: crawlability, indexability, useful people-first content, clear technical structure, page experience, and standard Search eligibility. We do not improve your SEO fundamentals or your website’s ranking in Google AI Overviews, AI Mode, or Google Search.

AgentReadyWebsite focuses on agent-readiness. We help AI agents that land on your website (research agents and assistants working inside Claude, ChatGPT, Copilot, Gemini’s deep research, Grok, Perplexity, and similar tools) find your business facts and understand what you offer.

See the FAQ for how generative AI search visibility differs from agentic browsing, which is the job we focus on.
