That includes AEO, GEO, AI visibility, answer-readiness, entities, citations, comparison pages, glossary content, structured content, and topical coverage.
Core AEO terms
AEO
Answer engine optimization. The work of making a site more visible and usable in AI-generated answers.
GEO
Generative engine optimization. A broader term often used for visibility across generative AI discovery environments.
AI visibility
How likely a brand or page is to appear, be cited, or be referenced in AI-generated outputs.
Answer-readiness
Whether a page is clear, structured, and complete enough to be reused in an answer.
Citations
References or source mentions used by AI systems when forming answers.
Entities
Recognizable concepts such as brands, products, categories, and terms that help AI systems understand what a page is about.
Page and content terms
Category page
A page that explains a topic, product space, or service area in a broad and structured way.
Comparison page
A page that explains the differences between two options, products, or approaches.
Alternatives page
A page that helps users understand substitute options and tradeoffs.
FAQ content
Question-and-answer content that provides direct responses to recurring user questions.
Glossary content
Pages that define important terms and help establish clearer topic coverage, especially in jargon-heavy categories.
Structured content
Content organized in a way that is easy to scan, extract, and summarize.
Topical coverage
How fully a site addresses the important questions, comparisons, and terms in its category.
Workflow terms
AEO audit
A structured review of how ready a site is for AI-generated answers, including gaps in clarity, page coverage, content structure, and support architecture.
Support pages

How easy it is for AI systems to identify and reuse useful statements, definitions, and comparisons from a page.

How to use this glossary in practice
Use this glossary to review your own site and ask:
- Are the key terms on our site explained clearly?
- Do we have the right support pages?
- Are our comparison pages and FAQs strong enough?
- Is our category language consistent?
- Are our most important pages truly answer-ready?
From terminology to action
Glossaries are helpful because they make cross-team conversations clearer. But the real value appears when those terms lead to better audits, sharper page planning, and better execution.
