What is answer engine optimization (AEO)?

Answer engine optimization (AEO) is the work of making your business easy for AI tools to find, read and describe correctly when a customer asks them a question. It stands on the same foundation as search engine optimization (SEO). GEO, short for generative engine optimization, is another name for much the same goal.

What is an answer engine?

An answer engine replies to a question in sentences, usually with links to the pages it drew on. ChatGPT, Perplexity, Microsoft Copilot, and Google’s AI Overviews and AI Mode work this way, and Anthropic says Claude may access websites when someone asks it a question.

Perplexity says each answer includes numbered citations linking to the original sources. OpenAI says ChatGPT can search the web for current information and that responses using web search may include citations.

What does answer engine optimization mean?

In this library, AEO means the practical work on your website and listings that lets these tools reach your pages, understand what you do and where, and point to you as a source.

It is mostly about clear facts, stated the same way everywhere a tool might look.

Where does GEO fit?

Generative engine optimization was introduced in a research paper first posted to arXiv in November 2023 and accepted to the KDD 2024 conference. Its authors described GEO as a way “to aid content creators in improving their content visibility in generative engine responses.”

Microsoft uses the term in its Bing Webmaster Guidelines, which say GEO “focuses on content eligibility for grounding and reference in AI responses.” The same guidelines say GEO does not guarantee grounding or citations, just as SEO does not guarantee rankings.

AEO and GEO describe the same goal. This library uses AEO throughout.

How does AEO relate to SEO?

AEO depends on SEO. Google’s guide to AI features and your website says “there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.”

To be eligible as a supporting link in those features, Google says a page must be indexed and eligible to be shown in Google Search with a snippet.

Microsoft says the same of its own products. Per the Bing Webmaster Guidelines, “Bing and Copilot search experiences rely on the same core crawling, indexing, and ranking foundation as traditional search.” The differences lie in what you check and how you measure, covered in AEO vs SEO.

What does AEO mean for a local business?

When someone asks an assistant for a local service, the assistant has to work out where they are and which businesses serve that area. OpenAI says ChatGPT may use an approximate location based on the person’s IP address, and may share location with “trusted third-party providers that help provide more local information, such as nearby business listings.”

That makes your listings part of AEO. Google’s AI features guide asks site owners to check that their Business Profile information is up to date.

Microsoft’s AI Performance announcement recommends Bing Places for Business to keep address, hours and contact information “current and eligible for inclusion in AI-generated responses.”

What does AEO work involve?

1. Let the search crawlers in. OpenAI’s crawler overview says: “Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers, though can still appear as navigational links.” Perplexity and Anthropic document their own search crawlers, PerplexityBot and Claude-SearchBot.
2. Put the facts in text. Google advises “making sure that important content is available in textual form.” A Microsoft Advertising blog post warns against hiding important answers in tabs or putting key information only in images.
3. Describe the business the same way everywhere. Bing’s guidelines ask for “clear and consistent naming for people, organizations, products, and locations.”
4. Keep listings accurate. Your Google Business Profile and Bing Places listing carry your address, hours and phone number.
5. Answer customers’ questions on focused pages. Bing says URLs focused on a primary topic are more likely to be selected for grounding results, and that essential information belongs near the top.
6. Measure what you can. As of October 2026, Google Search Console has generative AI performance reports that show impressions in AI features. Bing Webmaster Tools introduced an AI Performance report in public preview in February 2026 that shows how often a site’s content is cited in generative answers.

The AI visibility checklist turns these into yes-or-no checks you can run yourself.

What can AEO not promise?

No one controls what an assistant says. Google states that “indexing and serving isn’t guaranteed,” and Microsoft says GEO does not guarantee citations in AI experiences.

Bing says following its guidelines “helps ensure your URLs are eligible for” grounding results and citations. AEO is the work toward that eligibility. It does not decide the answer. How Ultruxy approaches the work is on the AEO service page.
