Answer Engine Optimization (AEO)

Answer engine optimization is the practice of making a business easy for AI assistants and answer features to quote and recommend: publishing direct, factual, well-structured answers that ChatGPT, Perplexity, Google's AI Overviews, and voice assistants can lift and attribute. It extends SEO rather than replacing it.

Search engines return links; answer engines return an answer. AEO optimizes for the second case: the assistant reads a handful of sources, synthesizes a recommendation, and names businesses. The work is making your pages one of those sources — direct answers under question-form headings, facts stated plainly (prices, service areas, credentials), consistent data everywhere the assistant might look, and evidence worth quoting.

Roughly 80% of AEO is indistinguishable from competent SEO. The new 20% is formatting for extraction and measuring the answer layer, which no traditional rank tracker sees.

The formatting discipline is easy to state and unnatural to follow: answer first, elaborate second. Most business writing builds to its point, because that is how persuasion works on humans. Extraction rewards the opposite. A heading that asks the buyer's actual question, followed immediately by a complete 40–60 word answer that stands alone if lifted out of the page, is quotable. The same information delivered as a narrative that resolves in paragraph four is not.

The measurement half is where most AEO effort goes wrong, because it is the half nobody can fake. There is no console for this channel. If a vendor reports your "AI visibility score" without showing which questions were asked, which assistants answered, whether web search was enabled, and how many answers were sampled, the number is decoration. Ask for the raw answers.

The honest scope also matters. AEO does not make an unremarkable business remarkable — assistants are synthesizing evidence other people created, mostly reviews and third-party coverage, and no amount of markup substitutes for that. What it does is ensure a business that genuinely deserves recommending is legible enough to receive one.
