Key takeaways
- AEO makes your business the source AI assistants quote, cite or recommend.
- It builds on SEO: crawlable, clear, specific, current and consistent content wins.
- Measure it by testing your buyers' questions across assistants every month.
AEO in one paragraph
Answer engine optimization (AEO) is the practice of making your content and your business the source that AI assistants and AI search features quote, cite or recommend. It targets ChatGPT, Gemini, Claude, Perplexity, Copilot, Grok, Google’s AI Overviews and AI Mode, and voice assistants.
| SEO | AEO | |
|---|---|---|
| Goal | Rank a link on a results page | Be the answer — quoted, cited or recommended by an AI assistant |
| Where | Google and Bing results | ChatGPT, Gemini, Claude, Perplexity, Copilot, Grok, Google AI Overviews and AI Mode, voice assistants |
| What wins | Relevance, links, technical health | Clear answers, trusted entity facts, structured data, citations to sources, mentions across the web — on top of good SEO |
| How it’s measured | Rankings, clicks | How often you’re named or cited for the questions your buyers ask |
“GEO” (generative engine optimization) is used for much the same work. The terms overlap — what matters is that SEO stays the foundation and AEO builds on it.
How answer engines choose what to say
- Search-connected answers pull pages from a search index at the time of the question — Google’s for Gemini and AI Overviews, Bing’s for ChatGPT search and Copilot, and other indexes for other assistants — then summarise and cite them.
- Built-in knowledge comes from what the model learned in training, drawn from the public web: websites, profiles, directories, forums and news. That’s why consistent mentions across the web matter.
- Both reward the same things: pages that are crawlable, clear, specific, current and consistent with what the rest of the web says about you.
- Academic work on “generative engine optimization” found that adding citations to sources, quotations and statistics made content noticeably more visible in AI-generated answers.
A 12-point AEO checklist
- AI crawlers (and Bingbot and Googlebot) are allowed in robots.txt.
- The site is verified in Google Search Console and Bing Webmaster Tools, with a sitemap that has accurate last-modified dates.
- New and updated pages are pushed to search engines quickly (IndexNow, indexing requests).
- An
llms.txtsummary — and ideally a full-text version — tells AI systems what you do. - One consistent description of your business everywhere: website, LinkedIn, directories, Google Business Profile.
- Organization, Person, Service, FAQ and article structured data, with profiles linked via
sameAs. - Every key page answers its main question in the first two or three lines.
- Headings phrased as the questions buyers actually ask.
- Specifics: numbers, dates, rules, comparisons — not generic marketing copy.
- Sources cited and a visible “last reviewed” date.
- Pages for each service in each market you serve.
- A monthly test: ask the main assistants your buyers’ questions and record whether you’re named.

Common mistakes
- Treating AEO as a replacement for SEO — it’s built on top of it.
- Blocking AI crawlers by accident (often through a security plugin or CDN setting).
- Different business descriptions on different profiles, which makes assistants unsure who you are.
- Believing anyone who guarantees placement in AI answers.

Frequently asked questions
What is AEO in marketing?
Answer engine optimization — optimising content and business information so AI assistants and AI search features (ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews) quote, cite or recommend you when people ask questions.
Is AEO the same as GEO?
They overlap heavily. GEO (generative engine optimization) is often used for being cited in generative AI answers; AEO is often used more broadly for answer-style results including featured snippets and voice. In practice the same work serves both.
Does AEO replace SEO?
No. AI assistants rely on search indexes and on what the web says about you, so SEO remains the foundation; AEO adds answer-first content, entity consistency and AI-specific access.
How do you measure AEO?
By testing a fixed set of buyer questions across assistants each month and recording whether you're named or cited, alongside Search Console and Bing data for the pages those answers draw on.
