What is the difference between AEO and SEO?

SEO works to rank your pages in a list of search results, while AEO works to get your business named inside the answer an AI engine writes, so SEO is measured by position and AEO by how often the answer names you.

SEO and AEO share a foundation, because AI engines often read the same pages search engines rank. They differ in the result: SEO wins a place in a list of links, AEO wins a mention, recommendation or citation inside an AI answer. AEO adds work SEO does not cover, such as tracking AI answers, earning a place on cited sources, and measuring AI Share of Voice.

SEO and AEO are close relatives with different goals. SEO gets your pages into a list of search results. AEO, answer engine optimization, gets your business into the answer an AI engine writes. Most businesses now need both.

The short version

Where you appear. SEO: a list of links. AEO: inside an AI-written answer.
What you win. SEO: a position on the page. AEO: a mention, recommendation or citation.
How it is measured. SEO: rankings, clicks and traffic. AEO: AI Share of Voice and the Citation Ladder.
Engines. SEO: Google and Bing. AEO: ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews and Grok.

What they share

A lot. AI engines often read the same pages search engines index, so the SEO basics still pay off: pages that can be crawled and indexed, clear titles and headings, fast pages that work on a phone, structured data, and accurate content other sites link to. If your site is weak on SEO, AEO is harder.

Where they differ

The result is different

A search results page shows ten or more links. An AI answer often names three or four businesses and stops. There is no page two. Either the answer names you or it does not.

The sources are wider

An engine writing an answer leans on review sites, directories, "best of" lists, press and associations as well as your own site. Ranking your own page well is not enough if those sources name your competitors and not you.

The measurement is different

Search rankings are fairly stable from one search to the next. AI answers vary each time a question is asked. That is why AEO is measured as a share across many asks, your AI Share of Voice, and by how you are named, using the Citation Ladder.

Do you need both?

Yes, if your customers use both Google and AI assistants, which most now do. Start with SEO basics, then add the AEO work on top: answer-first pages for real questions, AI crawler access, consistent listings, a presence on cited sources, and weekly tracking.

Questions

Do I still need SEO if I do AEO?

Yes. Many AI engines read the pages search engines rank, so indexable, fast, well-structured pages help both. AEO builds on SEO rather than replacing it.

Can I rank first on Google and still be missing from AI answers?

Yes. An AI answer names only a few businesses and draws on many sources beyond one ranking, such as review sites and lists, so a strong Google position does not guarantee a mention.

How is AEO measured?

By how often AI answers to your customers' questions name you compared with competitors, known as AI Share of Voice, and by how you are named: linked, recommended or just mentioned.

Is AEO the same as GEO?

In practice, yes. Generative engine optimization (GEO) and AEO describe the same goal of being named and cited in AI-written answers.
