The five
pillars.

The conceptual spine of Answer Engine Optimization and Generative Engine Optimization — five canonical pillar articles, each a Schema.org Article with a cross-reference to a DefinedTerm entry in the canonical register. Read in any order; each stands on its own.

What is AEO?

Answer Engine Optimization (AEO) is the discipline of structuring digital assets so that answer engines can extract, cite, and recommend a business or resource when users ask questions. The canonical pillar of the cluster, with a full breakdown of the five surfaces, the mechanics of citation, the distinction from SEO, and the relationship with GEO.

What is GEO?

Generative Engine Optimization (GEO) is the companion discipline focused on surviving the synthesis step when generative models compose a single answer from many sources. A source can be cited and still lose its wording during synthesis; a source optimized for GEO is quoted verbatim.

Choose Sources

The mechanics of AI citation. Which signals matter, which do not, and why dense structure outperforms volume. A breakdown of Schema.org markup, entity coherence, institutional anchoring, and the role of the llms.txt manifest in how language models select their sources.

Citation Mechanics

Under the hood of answer-engine citation. Retrieval, ranking, synthesis and the role of entity coherence in the pipeline. How a model moves from a query to a grounded answer with sourced citations, and where each structural signal enters the decision.

The five pillars and the twelve canonical terms together form the reference. Pillars explain; terms define. Every pillar references its canonical terms, and every term links back to the pillar where it lives.
