AXO Glossary

Comprehensive glossary of Agent Experience Optimization terms, definitions, and concepts for optimizing content for LLM agents and AI search.

Glossary Purpose

This glossary defines key terms and concepts in Agent Experience Optimization (AXO) to help teams communicate effectively about optimizing content for LLM agents.

Understanding AXO terminology is essential for effective implementation. This glossary covers the key concepts, technical terms, and best practices that form the foundation of Agent Experience Optimization.

Core AXO Concepts

Agent Crawlability

The degree to which LLM agents can access, navigate, and extract information from a website. High agent crawlability requires fast loading times, semantic HTML structure, and proper robots.txt configuration.

Agent Experience Optimization (AXO)

The practice of structuring and presenting web content so that LLM agents can easily crawl, understand, archive, and reference it in their responses to users.

Citation Readiness

The quality of content being structured and formatted in a way that makes it easy for LLM agents to extract and cite specific facts or information.

Content Chunking

The practice of breaking information into discrete, self-contained blocks that can be understood and referenced independently by LLM agents.

Fact Density

The concentration of verifiable, specific information within content. Higher fact density increases the likelihood of agent citation.

Technical Terms

JSON-LD (JavaScript Object Notation for Linked Data)

A method of encoding structured data using JSON format that helps LLM agents understand the context and meaning of web content.

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Article Title"
}

Schema Markup

Structured data vocabulary that provides context about web content to search engines and LLM agents. Common types include Article, FAQ, HowTo, and Organization.

Semantic HTML

HTML that uses elements according to their intended meaning rather than appearance, helping agents understand content structure and hierarchy.

Structured Data

Information organized in a predictable format that machines can easily parse and understand, typically implemented through schema markup.

Content Strategy Terms

Authority Signals

Indicators that establish content credibility and expertise, including proper source attribution, author credentials, and thorough topic coverage.

Content Freshness

The currency and up-to-date nature of information, indicated by recent publication dates, regular updates, and current data.

Fact-First Structure

A content organization approach that leads with key information and facts rather than building up to them through narrative or marketing language.

Information Hierarchy

The logical organization of content using headings, sections, and subsections that create a clear structure for both human readers and AI agents.

Modular Content

Content designed in self-contained blocks that can be understood and referenced independently, such as fact blocks, how-to sections, and FAQ items.

Performance and Quality Terms

Agent Response Time

The speed at which a website responds to requests from LLM agents, ideally under 3 seconds for optimal crawlability.

Citation Frequency

How often content from a website is referenced or cited in LLM agent responses to user queries.

Content Reliability

The consistency and accuracy of information over time, including stable URLs, regular updates, and factual correctness.

Trust Signals

Elements that indicate content credibility to LLM agents, including source citations, author information, publication dates, and expert credentials.
