AI Ask ChatGPT, Claude, Gemini, or Perplexity a commercial question — “what’s the best project management tool for a small agency?” — and you get a synthesized answer naming three to five products, sometimes with citations. No list of ten blue links. No page two.
Answer engine optimization (AEO) is the practice of earning a place in those answers: being one of the brands the model names, and one of the sources it cites.
How AEO differs from SEO
SEO optimizes for a ranking algorithm that scores pages against a query. AEO optimizes for a language model that synthesizes an answer from two things:
- What the model already believes from its training data — brand associations that formed over years of the web being written.
- What it retrieves at answer time — most assistants now run live web searches and read a handful of pages before answering.
You can’t do much about a frozen training set this quarter. You can do a lot about retrieval: assistants disproportionately cite pages that answer the question directly, near the top of the page, in language a model can lift verbatim.
That changes the writing brief. A page built to rank can afford a slow wind-up; a page built to be cited cannot. The winning shape is closer to a well-run FAQ: the question as a heading, a self-contained answer in the first paragraph under it, evidence after.
What actually moves the needle
From our own testing across assistants, the recurring themes are:
- Answer-shaped content. Pages that state a direct, quotable answer early get cited; pages that bury it get skimmed and skipped.
- Third-party corroboration. Models are trained to triangulate. A claim that exists only on your own domain is weaker than one echoed by reviews, comparisons, and independent publications.
- Being present in comparisons. “Best X for Y” and “A vs. B” pages are the raw material of recommendation answers. If you’re absent from the comparison content in your category, you’re absent from the answer.
- Technical reachability. If AI crawlers can’t fetch your pages — blocked bots, client-side-only rendering, no sitemap — nothing else matters.
Measure before you optimize
The uncomfortable part of AEO is that you can’t feel your own visibility. The only way to know whether assistants mention you is to ask them, systematically: run the questions your buyers ask, across the major assistants, repeatedly over time, and track mentions and citations. Do it manually with a spreadsheet, or use a monitoring platform built for it — but do it before changing anything, or you’ll never know whether the changes worked.
