SEO vs. AEO vs. GEO: What's the Difference?

If you've talked to anyone about marketing recently, you've probably heard a few new acronyms alongside SEO. AEO and GEO get presented as brand-new disciplines, sometimes as replacements for SEO and sometimes as something you need to buy separately.

The reality is simpler. They describe different places people find information, and they share most of the same foundation.

The short version

SEO: being found in search results

Search engine optimization is the work of helping a website show up in organic search results for the things that matter to a business. It covers three broad areas:

• Technical: can search engines crawl, render and index the site? Is it fast, secure and mobile-friendly?
• On-page: does each page clearly target a service, topic or location, with useful content, good titles and logical headings?
• Authority: do other credible sites reference and link to the business?

SEO is still where most businesses should start. Everything else builds on it.

AEO: being the answer

More searches now end without a click. Someone asks a question, and Google, a voice assistant or an AI summary answers it directly on the results page.

Answer engine optimization is about making your content clear and well-structured enough that these systems can understand it and use it. In practice that means:

• Answering the real questions your customers ask, in plain language
• Putting the direct answer near the top, then expanding on it
• Using clear headings, lists and tables where they help
• Adding structured data (schema) so machines can read key facts reliably
• Building enough depth on a topic that your site is clearly an authority on it

A personal injury firm with a genuinely helpful page on "what to do after a car accident in Minnesota" is doing AEO. So is a painting company that clearly explains how long exterior paint should last.

GEO: being represented accurately by AI

Generative AI tools don't just pull a single answer from a single page. They synthesize information from across the web to describe businesses, compare options and make recommendations.

Generative engine optimization focuses on the signals those systems rely on:

• Entity clarity: is it obvious who your business is, what it does, where it operates and who runs it?
• Consistency: does your name, address, phone number and service information match everywhere it appears?
• Original expertise: do you publish first-hand knowledge that can't be found anywhere else?
• Mentions and citations: do credible third-party sources talk about you?
• Structured information: is key information marked up so it's easy to extract?

One honest caveat: no one can guarantee that ChatGPT or any other AI tool will recommend your business. These systems change constantly and don't publish how they decide. What you can do is make your business as easy as possible for them to understand and verify.

Where they overlap

Look closely and the overlap is obvious. A website with:

• clean technical foundations
• clear architecture, with a page for each service and location that matters
• helpful, original content that answers real questions
• consistent business information across the web
• structured data
• strong internal linking

…is well positioned for SEO, AEO and GEO. That's why we describe them as different channels built on one foundation.

What should a business actually do?

1. Get the foundation right first. A fast, crawlable, well-structured website with a dedicated page for each core service and location.
2. Answer your customers' real questions. Write down the questions you hear on sales calls and answer them properly on your site.
3. Make your business information consistent. Your Google Business Profile, directories, social profiles and website should all agree.
4. Show first-hand expertise. Case studies, real project photos, attorney or owner insights. These are things AI can't make up and competitors can't copy.
5. Monitor how you're represented. Periodically ask AI tools about your business and your services, and note what they get right and wrong.

None of this requires chasing a new acronym every quarter. It requires a website and a body of information that clearly and accurately describe what your business does.
