Is your site AI-readable?
Check whether your website publishes a Google Open Knowledge Format bundle — plus the llms.txt, structured data, and crawler access that let ChatGPT, Claude, Perplexity, and Google's AI understand and cite you.
What is Open Knowledge Format?
OKF is an open standard Google published in 2026 for packaging the knowledge about your business — products, topics, FAQs, definitions — as plain markdown files that AI agents read directly. Think of it as a wiki written for machines, the way sitemap.xml is written for crawlers.
Without an OKF bundle
- AI guesses about your business from scraped pages
- Inconsistent or wrong answers in ChatGPT & Claude
- No control over how you are summarized
- You are easy to misattribute or skip
With an OKF bundle
- AI loads your curated facts directly
- Accurate citations in AI answers (AEO/GEO)
- One source of truth, version-controlled
- Updated automatically as you publish
Frequently asked questions
What does this checker actually test?
It fetches your site as a crawler and probes for an OKF bundle at /.well-known/okf/ and /okf/, an llms.txt file, JSON-LD structured data on your homepage, a machine-readable title and description, an XML sitemap, and whether robots.txt blocks AI crawlers. Each becomes a signal in your AI-Readiness Score.
Is OKF the same as schema.org / JSON-LD?
No. Schema.org markup lives inside your HTML and describes one page. OKF is a separate bundle of markdown files describing your whole organization’s knowledge, published for AI agents to load wholesale. They complement each other — the strongest sites do both.
How do I add an OKF bundle to my site?
SEOAgent generates one from your business context and published content, then keeps it in sync as you publish. You host the resulting markdown files at /.well-known/okf/ or /okf/ (or link them from llms.txt). You can also run it locally in your coding agent with one command.
Why does AI-readiness matter for SEO?
A growing share of search happens inside AI assistants and AI Overviews, where being cited depends on whether the model can find and trust a clear, structured account of your business. This is called Answer Engine Optimization (AEO) or Generative Engine Optimization (GEO), and OKF is purpose-built for it.
