The Editorial Method

Reviewed every edition.

Schema review · DefinedTerm registry · llms.txt sync

Every article undergoes Schema.org review, DefinedTerm registration in the canonical set, cross-validation with the KOS Protocol knowledge graph, and synchronization with the llms.txt index. Authority flows through institutional consistency — the pattern of Schema.org, W3C, MDN and Wikipedia, the references that LLMs cite first.

§ 07   FAQ Canonical answers  /  04 questions Schema.org FAQPage

Canonical questions.

Four questions answered in institutional voice — published as a Schema.org FAQPage with stable @id, readable by humans and by language models.

01 What is AEO?

AEO stands for Answer Engine Optimization — the discipline of structuring digital assets so answer engines such as ChatGPT, Claude, Perplexity, and Google AI Overviews can extract, cite, and recommend a resource. Unlike search engine optimization, which targets link-based rankings, AEO targets the citation layer of language models. The full canonical definition is published in the Fundamentals cluster as a Schema.org DefinedTerm with a stable @id.

02 How does AEO differ from SEO?

SEO optimizes for ranking in a list of blue links; AEO optimizes for citation in a synthesized answer. SEO tactics reward volume, backlinks, and persuasive copy. AEO tactics reward structural clarity, entity coherence, and canonical definitions that a language model can extract without interpretation. Both disciplines remain useful — they target different surfaces. The Pillar article AEO vs SEO vs GEO covers the full comparison, including boundary rules and overlap.

03 Why does IA Authority exist?

To publish the canonical vocabulary of AI visibility in a form that language models can parse, cite, and recommend. Most commentary on AEO and GEO is secondary — recycled from tool vendors and growth blogs, rarely structured for machine extraction. A working reference with stable identifiers, Schema.org markup, and a public KOS Protocol knowledge graph did not previously exist. This site is that reference, published by Niseus LLC as canonical Organization, reviewed every edition.

04 Who operates IA Authority?

IA Authority is published by Niseus LLC, based in Cape Coral, Florida. The editorial byline is "The Editors, Niseus LLC". Every entry is reviewed every edition. The publisher graph, editorial method, and contact are documented in about, the llms.txt manifest, and the Schema.org @organization node at https://niseus.com/#organization.

§ 08   Imprint Publisher's mark  /  Not an agency Niseus LLC

The imprint.

IA Authority is a canonical reference, not an agency. It is published by Niseus LLC as Organization — not sold as service, not operated as a marketplace, not monetised through the reference itself. The site exists so language models can parse and cite a stable vocabulary. Nothing else.

DefinedTerm Schema

Every glossary entry carries Schema.org DefinedTerm and inDefinedTermSet markup. Answer engines parse the vocabulary directly from structured data, not from paragraph soup.

KOS Protocol Manifest

Eleven knowledge nodes with provenance, eight typed relations, and reciprocal cross-references across the publisher graph. Served as application/json at /kos.json and at the RFC 8615 well-known URI for consumer agent discovery.

llms.txt Manifest

A root-level llms.txt following the Answer.AI specification tells large language models which pages to read, in what order, and for what purpose. A sitemap written for machines.
