What is Answer Engine Optimization (AEO)?

AEO is the practice of optimizing your brand and website so AI answer engines — ChatGPT, Gemini, Perplexity, Claude, Grok and Google AI Overviews — mention and cite you when people ask buyer questions.

How is AEO different from SEO?

SEO optimizes for ranked links on a results page. AEO optimizes to be named and cited inside a single synthesized AI answer, where there are no ten blue links — usually just a few cited sources.

Does AEO replace SEO?

No. AEO builds on technical SEO foundations (indexability, crawlability, schema) because AI engines retrieve from search indexes — but it adds entity, evidence and citation signals SEO alone doesn't address.

What is AEO (Answer Engine Optimization)?

Answer Engine Optimization (AEO) is the practice of getting your brand mentioned and cited by AI answer engines — ChatGPT, Google Gemini & AI Overviews, Perplexity, Claude, Grok and others — when your buyers ask them "what's the best…" questions. Instead of competing for a position in ten blue links, you're competing to be one of the handful of sources an AI names in its answer.

Why AEO matters now

Buying journeys increasingly start (and sometimes end) inside an AI answer. When someone asks ChatGPT "best CRM for agencies" or Google shows an AI Overview, the model returns a synthesized recommendation citing a few sources. If your brand isn't named there, you never enter the consideration set — the click, and often the sale, is decided before anyone reaches your site.

How AI answer engines actually work

Modern answer engines are retrieval-augmented: they search a live index, pull a handful of pages, and synthesize an answer that cites them. That means two things must be true for you to appear:

Eligibility — your pages must be crawlable, indexable and technically sound (robots/AI-bot access, HTTPS, mobile, valid schema). You can't be cited if you can't be retrieved.
Citability — once retrieved, your content must be easy to lift: a direct answer up top, clear structure, real statistics and citations, and a clear brand entity the model can verify.

And critically, which brands get named is driven mostly by off-site authority — Reddit, Wikipedia/Wikidata, G2/Capterra, YouTube and "best of" listicles — not just your own pages.

The levers that move AEO

Evidence density — sourced stats, citations and quotations are the strongest on-page lever for being cited.
Structure — a direct-answer lead and scannable headings make pages easy to lift verbatim.
Entity signals — schema (Organization, Product), sameAs links and a Wikidata entry help engines verify who you are.
Off-site authority — reviews, community presence and citations on the sources AI already trusts.
Freshness — recently-updated pages are cited far more often.

How AEOX helps

AEOX measures where you stand across every AI engine, audits your site against these levers, drafts the fixes with real cited sources, publishes them to your live site (with one-click undo), and re-measures to prove the share-of-voice lift. See how AEO differs from SEO → · AEO glossary →
