Answer Engine Optimization (AEO): getting cited in ChatGPT, Perplexity & Google AI Overviews

Definition

What AEO is — and what it isn't

AEO optimizes for being cited as a source in answer engines — systems that answer a question not with ten links, but with a generated text and a few source references alongside it. Success is measurable by a single question: does your domain show up in the answer?

AEO is not a replacement for classic SEO; it builds on it. A page that cannot be indexed or crawled cannot be cited either. The technical foundations remain; only the goal shifts from the ranking to the citation.

Distinction

AEO and GEO: the difference

AEO and GEO overlap heavily and are often used interchangeably. The difference lies in the focus:

• GEO (Generative Engine Optimization) is the broader term — visibility in generative systems as a whole, across answers, summaries and recommendations.
• AEO (Answer Engine Optimization) is narrower and targets the direct answer: the citable passage and the visible source link in an answer engine.

In practice the boundary is fluid. Anyone doing AEO is almost always doing GEO too. The levers are almost the same; AEO merely sharpens the focus on the citation.

Practice

The levers: how to write citably

Answer engines extract, weigh and cite passages. Anything that makes these three steps easier increases the chance of a citation.

1. Give the answer first. A concise, self-contained answer goes up top — in the first paragraph, understandable even without the rest of the page. This is the most important principle of AEO.
2. Work in Q&A and FAQ format. Questions the way people ask them, with direct answers below. Answer engines map their prompts more easily onto clearly worded questions.
3. Provide structured data. FAQPage, HowTo and Article as JSON-LD make the meaning machine-readable — and the visible text must match it exactly.
4. Clarify entities and authority. Who is writing, about what, with what grounding? Clear entities and established authority lower the risk of being omitted or confused.
5. Deliver fresh, verifiable facts. Visible timestamps and checkable statements. What can be substantiated is more likely to be picked up than an unsupported claim.
6. Build snippet-ready passages. One thought per sentence, short self-contained paragraphs. A passage that holds true even outside its context is a passage that can be cited.

Platforms

How the engines find sources

Every answer engine sources its material differently. Anyone optimizing for them should know what they draw on.

The conclusion is unspectacular: whoever is classically well indexed (Google, Bing) and additionally writes citably covers most engines at once. Live-retrieval systems like Perplexity additionally reward fresh, clearly liftable passages.

Measurement

How to measure AEO

Classic rankings say little about whether an answer engine cites you. The relevant metric is the frequency of mentions and citations in AI answers.

What you measure

The mention and citation frequency of your own domain in generated answers.

How you measure

Repeatedly put a defined set of relevant questions to the engines and log whether and how the domain appears as a source.

What you don't claim

No invented click or percentage figures — the data situation is young, and verifiable observation beats any wishful statistic.

How KAMINSKI+ practices this

We don't just assert these principles — we build the website according to them. Our Grounding pages are FAQPage and grounding pages on which visible text and JSON-LD match exactly, one fact per sentence, with visible timestamps. The Guide records the writing rules that make a passage citable, and the reference on GEO places AEO within the larger picture of generative visibility. For us, grounding is not theory but the method of construction.
