AI Answer Visibility Glossary
AI Answer Visibility Glossary
This field has too many names (GEO, AEO, LLMO, AI SEO) for one simple goal: AI answer visibility, meaning your brand gets understood, trusted, and cited by AI. This glossary sorts the vocabulary out.
One rule decides what gets an entry: would a founder, marketer, or practitioner actually ask about it? Every entry opens with a quotable one-sentence definition, then unpacks the mechanics, the relationships between terms, and the common misconceptions. Where Daimonia’s own services are relevant, they appear in a clearly marked block; the definitions themselves stay neutral.
Category & Methods
-
AEO (Answer Engine Optimization)
AEO (Answer Engine Optimization) is optimization aimed at 'answer engines': search systems that respond with a direct answer rather than a list of links. Its goal is the same as GEO's: AI answer visibility for your brand.
-
AI answer visibility
AI answer visibility is the degree to which your brand gets mentioned, accurately described, and recommended when users ask AI assistants (ChatGPT, Gemini, Perplexity, Doubao) questions relevant to your business.
-
GEO (Generative Engine Optimization)
GEO (Generative Engine Optimization) is the practice of making brand content easier for generative AI to understand, trust, and cite, with one goal: AI answer visibility, meaning your brand shows up in the answers AI gives.
-
GEO vs AEO vs LLMO vs AI SEO
GEO, AEO, LLMO, and AI SEO are different communities' names for the same practice: making a brand understood, trusted, and cited by AI so it earns AI answer visibility. The differences are etymology, not workload.
-
GEO vs SEO
SEO optimizes where your pages rank on a results page; GEO (Generative Engine Optimization) optimizes whether your brand appears inside AI answers. One competes for position, the other competes to be the answer: shared foundations, different judges.
Daimonia Methodology
-
Agent-to-Agent Marketing
Agent-to-Agent Marketing (A2A Marketing) is a paradigm coined by Daimonia: the brand's AI agents produce and distribute brand signals, and the AI agents users rely on (ChatGPT, Gemini, Doubao, DeepSeek) read, evaluate, and cite them. Marketing moves from brand-to-human to agent-to-agent.
-
Brand visibility rate & content citation rate
Brand visibility rate is the share of AI answers to a relevant question set that mention your brand; content citation rate is the share that cite your own content (site, knowledge base). Together they are the standard way to measure AI answer visibility.
Technical Foundations
-
AI search
AI search is the search format where a large model generates the answer directly: the user asks a question, the AI retrieves and synthesizes multiple sources, and responds with one composed answer, often with citations, instead of a page of links.
-
llms.txt
llms.txt is a file at your site's root written specifically for large language models: a compact Markdown briefing that tells AI who this site is, what it covers, and which pages matter most.
