If you’re serious about showing up inside AI answers — whether that’s Google’s AI Overviews, ChatGPT, Perplexity, Gemini, or Claude — you need language that machines and people both respect. That’s where this glossary comes in.
I built it for executives, consultants, and operators who keep hearing terms like Generative Engine Optimization or Semantic SEO and wonder, “What does that actually mean in practice?” Each entry here is short, plain-English, and tied to the reality of how large language models (LLMs) select, rank, and cite sources.
A quick note: I’ve included both established industry phrases (AI SEO, Semantic SEO, Answer Engine Optimization) and emerging ones we’re shaping here (LLM Visibility™, AI Discoverability Framework™). Together they form the language of the next chapter in digital growth.

AI SEO
AI SEO uses AI to accelerate strategy: entity mapping, structured summaries, schema, and editorial judgment. AI speeds the work; it doesn’t replace taste or authority.

Generative AI SEO
Search is shifting to answer-first. Make pages “quote-ready”: a crisp 40–60-word definition up top, sources and nuance below, plus schema/FAQs so models lift the right lines.

LLM SEO
LLM SEO is about getting selected and cited by ChatGPT, Gemini, Claude, Perplexity, and Grok. It’s clarity of entity, consistency of facts, and proof from credible places.

Semantic SEO
Organize around entities and relationships, not just keywords. When your site mirrors the knowledge graph, both humans and models understand you faster.

Answer Engine Optimization (AEO)
AEO is winning the direct answer. Lead with the answer, format for skimming, add FAQ schema, and cite well. Simple idea — disciplined execution.

Generative Engine Optimization (GEO)
GEO targets engines that generate multi-paragraph responses. Think answer-readiness plus off-site proof (press, directories, talks) that models already trust.

ChatGPT SEO
This isn’t prompt tricks. It’s eligibility. Clear entities, sourced language, and echoes from credible outlets ChatGPT reads.

AI Visibility
How often AI systems surface you — your name, company, and frameworks — for relevant questions. Built on clarity, citations, and repetition across channels.
