Answer Engine Optimization (AEO) is the practice of structuring content so that AI answer engines like ChatGPT, Perplexity, and Google AI Overviews quote it directly in their answers, instead of just ranking it somewhere in a list of links.
Classic SEO fights for a position on a results page. AEO fights to be the source the engine actually quotes when it writes its answer. The engine reads your page, decides whether it holds a clear answer to the question, and either cites you or moves on. There's no second page of results to fall back on.
The reason the playbook differs is that the reader differs. A ranking algorithm sorts hundreds of pages into an order. An answer engine grabs a few candidate passages and has a language model read them and choose what to quote. AEO is the work of being the passage it chooses.
Why it matters
Discovery is moving from a page of ten links to a single written answer. When an AI Overview or a Perplexity response settles the question on the spot, a top ranking earns you nothing unless you were the source it cited. You can hold the number-one spot on Google and still be missing from the answer the buyer reads.
For B2B that's where the deal starts. Much of a buyer's research now happens inside an AI conversation, well before they ever reach your site, so being absent from those answers means being absent from the shortlist.
How to optimize for it
- Put the answer first. Lead the section with a direct, self-contained response before you pile on context or caveats, because engines quote passages that stand on their own.
- Use the buyer's phrasing. Turn the questions people actually type ("how much does X cost", "X vs Y") into headings and answer them right underneath.
- Make answers easy to lift. Clear headings, short definitional passages, and the odd table are simpler for a retrieval system to isolate than an answer buried mid-paragraph.
- Give the engine a reason to trust you. Cited data and a named author push a passage up the shortlist, and source authority is often what settles the tie.
A pricing page that opens with "Plans start at $X per month for up to Y seats" gets quoted when someone asks an engine what the product costs. Bury that number in paragraph four, behind a founder story, and the engine reaches for a competitor who led with it.
