Answer Engine Optimization

AEO

The practice of getting a business's content extracted as a clear, direct answer inside an AI system's response — rather than ranked as a link on a results page most people no longer scroll through. AEO rewards concise, well-structured content that directly answers a specific question.

Generative Engine Optimization

GEO

The practice of building the depth, original research, and cross-source corroboration that makes an AI system treat a brand as a trusted, repeatedly-cited authority — not just a single extractable answer. GEO is slower and more compounding than AEO, since it depends on multiple credible sources reinforcing the same facts over time.

The umbrella term

AI SEO

The everyday, more commonly searched umbrella term for optimizing a business's visibility inside AI-generated answers. Usually refers to AEO and GEO work together — don't get hung up on which term a given agency uses; the underlying work is what matters.

The systems themselves

Answer Engine

An AI system — such as ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot, Gemini, or Claude — that responds to a query with a direct, synthesized answer instead of a list of links to click through and read yourself.

Measuring & improving the outcome

AI Citation Optimization

The practice of increasing how often, and how favorably, a business is named and cited inside AI-generated answers — combining technical work (structured data), content work (extractable answers), and ongoing measurement, since citation performance shifts as platforms update.

The mechanism

RAG (Retrieval-Augmented Generation)

The mechanism most AI answer engines use to generate responses: searching the web, pulling a set of candidate pages, and writing an answer grounded in the pages that most clearly and credibly address the question — rather than relying purely on memorized training data. First documented in a 2020 research paper, well before the current AI search boom.

The metric

Citation Share

A measure of how often, and how favorably, a brand is cited by AI systems for relevant queries — typically tracked across multiple platforms and scored on a fixed scale, rather than a single pass/fail check. CiteHQ.io measures citation share across six AI platforms on a fixed 0–4 scale.
