Capxel Launches LLM-LD, the First Open Standard for Making Websites Readable by AI Agents
New specification gives brands a structured framework to surface in AI-powered search, recommendation engines, and autonomous agents
Capxel, the AI-native data company helping enterprises expand through intelligence-driven products, today announced the general availability of LLM-LD (Large Language Model Linked Data) — the first open standard designed to make website content natively readable by AI systems, retrieval pipelines, and autonomous agents.
LLM-LD defines standardized file formats, discovery mechanisms, and conformance levels that allow any AI system to understand a website's complete content from a single index file. The specification is available under a Creative Commons BY 4.0 license at llmld.org.
“JSON-LD solved machine readability for search engines. LLM-LD solves it for AI. Every major AI system — ChatGPT, Gemini, Perplexity, Claude — retrieves and synthesizes web content differently than traditional search crawlers. There was no standard for how websites should present themselves to these systems. Now there is.”
“We're seeing a shift in how forward-thinking brands approach their digital presence. The companies that structure their content for AI agents today will be the ones those agents recommend tomorrow. LLM-LD gives every brand — regardless of size or technical capability — a clear path to get there.”
As AI agents increasingly mediate how consumers discover products, services, and information, brands face a new visibility challenge. Recent industry research found that fewer than 1.2% of brand locations receive direct recommendations from leading AI assistants — not because the businesses lack quality, but because their content isn't structured for AI consumption.
LLM-LD addresses this with a standardized index file, structured entity data, knowledge graphs, product feeds, an AI Discovery Page specification, and three conformance levels from basic discoverability to full agent-readiness.
Since its launch, LLM-LD has seen rapid adoption across multiple industries including healthcare, luxury retail, professional services, and e-commerce. The companion LLM Disco Network (llmdisco.com) has attracted implementation partners across the agency ecosystem.
LLM-LD is free and open. Any developer, agency, or platform can implement it without licensing fees or vendor lock-in. Capxel provides enterprise-grade implementation services for brands requiring managed deployment, ongoing optimization, and performance analytics.
