Core Concepts
AI Citation
AI citation refers to when AI systems like ChatGPT, Claude, and Perplexity reference and link to your website as a source in their responses. Unlike traditional SEO rankings, AI citations appear directly in AI-generated answers, providing immediate visibility and traffic.
E-E-A-T Signals
E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals demonstrate content quality and author credibility. AI systems evaluate E-E-A-T signals to determine which sources to cite, prioritizing authoritative and trustworthy content.
AI Visibility
AI visibility refers to how easily and frequently your content is discovered, understood, and cited by AI systems like ChatGPT, Claude, and Perplexity. It focuses on making content citation-worthy rather than optimizing for traditional search rankings.
Technical SEO
Entity Graph
An entity graph is a knowledge structure that maps entities (people, organizations, technologies, concepts) and their relationships in your content. AI systems use entity graphs to understand content context, topical authority, and semantic relationships.
Schema Markup for AI
Schema markup (structured data) helps AI systems understand your content type, entities, and relationships. Using JSON-LD format, schema markup provides explicit context that AI systems use to better comprehend and cite your content.
FAQ Schema
FAQ schema (FAQPage) is structured data that marks up question-answer pairs in your content. AI systems use FAQ schema to find direct answers to questions, making your content more likely to be cited for question-answering queries.
Content Strategy
Topic Clusters
Topic clusters are content structures with 1 hub page (2000+ words) covering a main topic broadly, and 8-15 spoke pages (1500+ words each) covering subtopics in depth. This structure signals comprehensive topic coverage and topical authority to AI systems.
Internal Linking for AI
Internal linking for AI optimization focuses on helping AI systems understand content relationships and topical authority. Strategic internal links create topic clusters and signal comprehensive topic coverage.
Topical Authority
Topical authority demonstrates comprehensive expertise on a specific topic through extensive, interconnected content. AI systems recognize topical authority through topic clusters, entity graphs, and comprehensive coverage.
Hub-Spoke Content
Hub-spoke content is a topic cluster structure with 1 comprehensive hub page covering a main topic broadly, and multiple spoke pages covering subtopics in depth. This structure signals comprehensive topic coverage to AI systems.
Analytics
Citation Probability
Citation probability is a score (0-10 or 0-100) that predicts how likely AI systems are to cite your content. It evaluates factors like content depth, structure, schema markup, E-E-A-T signals, and freshness.
Citation Tracking
Citation tracking monitors when and how AI systems cite your content. It involves analyzing referral traffic, server logs, and user agents to identify citations from ChatGPT, Claude, Perplexity, and other AI systems.
AI Optimization
Semantic Search
Semantic search understands the meaning and context behind queries, not just keyword matching. AI systems use semantic search to find relevant content based on meaning, synonyms, and conceptual relationships.
Query Intent
Query intent is what a user actually wants when they ask a question. AI systems classify query intent (informational, navigational, transactional, question-answering) to match queries with relevant content.
Content Optimization
Content Freshness
Content freshness refers to how recent and up-to-date your content is. AI systems prioritize fresh, current information, especially for time-sensitive topics. Freshness signals include publication dates, last updated dates, and current information.
AI Snippet Optimization
AI snippet optimization formats content snippets (paragraphs, lists, tables, definitions) to be directly cited by AI systems. Well-formatted snippets are 3x more likely to be quoted verbatim in AI responses.
Content Depth
Content depth refers to how comprehensively and thoroughly a topic is covered. AI systems prioritize deep, comprehensive content (1500+ words) over thin, surface-level content. Content depth signals expertise and authority.
