AEO Foundations
Answer Engine Optimization is making your content visible and useful to systems that answer directly instead of listing links: ChatGPT, Perplexity, Claude, Copilot, Gemini, and Google AI Overviews. This guide is the mental model the rest of the track builds on: how AI search works, why one prompt becomes many searches, and why getting cited is a probability rather than a ranking. It builds on your SEO, it does not replace it.

What AEO is (and what it is not)
AEO is making your content visible and useful to systems that answer directly instead of listing links. It builds on SEO, it does not replace it.
Two sources: training data vs live retrieval
Every AI answer comes from one of two places. The difference between them explains almost every tactic in the rest of the track.
Query fan-out: one prompt becomes many searches
A single prompt is expanded into a batch of synthetic sub-queries that run in the background. This is the single most important idea in AEO.
Citations are a probability, not a ranking
Ask the same question five times and you might get cited three of them. There is no fixed position, which is why we say AI visibility, not AI rankings.
Platforms do not agree with each other
Out of the top 50 most-cited domains across AI Overviews, ChatGPT, and Perplexity, only about 7 appear on all three. Treat them as one target and you leave visibility on the table.
Three outcomes, not win or lose
Any given AI answer lands you in one of three states, and two of them are worth having.
The strategy side is real work, but not this track
A lot of AEO advice is marketing strategy. It matters, but it needs marketing tooling and human effort, and other people teach it better than we can.
