What Is the Difference Between SEO, GEO, and AEO?

SEO aims for visibility on search engine results pages; GEO aims for appearing as a source or recommendation in generative AI answers such as ChatGPT and Perplexity; and AEO aims for visibility in answer areas by providing direct, short, and accurate answers. In practice, all three rest largely on the same foundation.

Your brand may be on the first page of Google, and yet when a buyer asks ChatGPT "which companies should I look at in this field?", your name may not come up. The reason is that visibility is no longer earned in a single place but across multiple answer surfaces.

This article distinguishes the three acronyms and explains what you need to do for each. Note: there is no single standard definition of GEO and AEO in the industry; the definitions we use here are working definitions.

What is the difference between SEO and GEO?

SEO is concerned with how a page ranks in search results; its measure of success is ranking and clicks. GEO looks at whether an AI assistant mentions you when answering a question; there isn't always a ranked list and a click, and most of the time there is an answer text.

The two overlap at most points: an accessible site, clear content, and a trustworthy brand presence are fundamental to both. The difference is in measurement and focus. In SEO, you ask "where do we rank?"; in GEO, you ask "are we mentioned when someone asks, and are we described correctly?"

What is the difference between AEO and SEO?

AEO focuses on making your content quotable as a direct answer. In practice, this means a short, clear paragraph at the top of the page that answers the question, question-style headings, and structured data that matches the text on the page. It can be thought of as a subset of SEO; however, the aim is less to get people to click through to the page than to be part of the answer itself.

Your brand is on Google, so why might it be missing from ChatGPT?

There are three common reasons:

Access: ChatGPT's search feature shows sites through OpenAI's search crawler. If you've blocked this crawler, you won't appear in ChatGPT's search answers; GPTBot, which is used for model training, is a separate setting. A CDN or firewall rule can also stop bots even when robots.txt allows them.
Inconsistent information: If your company description, services, and certifications are written differently on your site and in your public profiles, assistants can't describe you accurately.
Third-party presence: Assistants often cite directories, review sites, and industry publications as sources too. If you're not there, or your information there is wrong, your visibility drops.

Google, meanwhile, states that no special optimization is needed for AI Overviews and AI Mode and that SEO fundamentals still apply. In other words, doing well on Google doesn't mean doing well on ChatGPT, but there is a common foundation for both.

Sources: OpenAI crawler documentation, Google Search Central, AI features and your website.

How do you manage SEO, GEO, and AEO together?

Instead of running the three as separate projects, build a common foundation:

Verify access. Make sure your robots.txt and CDN rules allow the search crawlers you want.
Write direct answers. At the top of every important page, include a 40–60-word paragraph that answers the page's main question.
Keep information consistent. Your company description, services, locations, and certifications should be written the same way everywhere.
Match structured data to the page. Schema should reflect the visible text on the page and not claim more than it does.
Test regularly. Ask ChatGPT, Perplexity, and Google the questions buyers ask, record the results, and repeat every month.

Frequently Asked Questions

What is the difference between SEO, GEO, and AEO?

SEO aims for visibility in search results, GEO for being mentioned and cited as a source in generative AI answers, and AEO for being quoted in direct, short answer areas. There is no single standard definition of GEO and AEO in the industry; all three rest largely on the same foundation.

Is GEO replacing SEO?

No. Google states that no special optimization is needed for AI Overviews and AI Mode and that SEO fundamentals still apply. GEO adds separate tracking of visibility in AI answers on top of the same foundation.

How do I find out whether my brand appears in ChatGPT?

Ask ChatGPT, Perplexity, and Google the questions buyers ask; record whether your brand is mentioned, whether it's cited as a source, and whether it's described correctly. Because answers can vary, ask each question twice and repeat the check monthly.

What is AEO?

AEO (Answer Engine Optimization) is work aimed at having content quoted as direct, short answers. A clear answer paragraph at the top of the page, question-style headings, and structured data that matches the page are the foundation of this work.

Conclusion

Although SEO, GEO, and AEO are separate acronyms, they rest on a common foundation: an accessible site, direct answers, consistent information, and regular measurement. Having your brand on Google isn't enough; it also needs to be described correctly wherever buyers are asking.
